Bad aftermarket/ warranty Uneven wear on 1 out of 4. Tyre feathered. Contacted to see how good the so called warranty would be. Was told by [Name Removed] the wear is probably down to road conditions and wheel alignment, such a cope out that I’m sure would be the answer to standard answer.
Cooper Tyres ST/MAXX are out of this world – Not only do I highly recommend Cooper Tyres ST/MAXX for you next off road adventure or just cruising around the city. I can honestly say they are by far the best tyre on the market today. Yes the owner has a responsibility of checking tyre pressure regularly and getting wheel alignments to get the best out of these tyres or any tire. At the end of… Read more
the day if you want a long lasting tyre go Cooper Tyres ST/MAXX. I was in no way told to write this recommendation, I did this of my own free will as I have completed over 110,000klm on my tyres and still going.
These Tyres side walls split with no impact or stakes like they fatigue & tear – Had on F250 for less than 15000km highway , gravel roads some on farm use All 4 tyre split on side walls 2 complete flat other 2 just starting waiste off $$$$ Show details

Coopers ST Maxx after 50,000km – Purchased 6 tyres that won’t balance and despite different methods and rotation, still significant steering shake. Dealer said Coopers told them cause was steel rims not tyres. Swapped steel rims but steering shake still present. Chips n splits on rear protected spares 2years ago. Didn’t claim “warranty” as dealer said Coopers only reimburse a fraction of new tyre. Very disappointed. Not getting Coopers again. Show details

Torture tested – I have a set of 315/75R16s on my 79 dual cab cruiser that weighs 3200kg before loading it up. I run them at 42psi cold for highway driving and most gravel and easy offroading. For rougher off-road work I find that they bag out pretty well at 32psi and I haven't needed to go lower than this even in sand. I have read reports of them delaminating at… Read more
low PSI on long trips and this may be due to the thicker side wall retaining heat then failing. So far I haven't had any punctures or failures and the tyres have been excellent on tarmac, gravel, mud and sand. On the highway they are well quieter than mud tyres despite having massive outer lugs. Being a 35 inch tyre sitting under a big lifted rig means they do rock and roll a bit around higher speed corners but never seem to lose traction. I have done 65,000kms with lots of rough 4wding carrying a lot of weight and through rotating every 10,000kms I will probably get close to the 80,000km rating. Overall I think I will buy them again so long as they keep making them in the USA.
Wrong choice of tyre – Got the Dmax LSM in early 2018 and as expected the factory tyres were only meant to impress on highway driving so I quickly subbed them out for a set of these ST MAXX in 265/70R16(as recommended by Cooper retailer)The original tyres were 245/70R16 but was assured the difference was minimal. So the fuel economy was quickly destroyed from around… Read more
8.4L/100km to 10.4L/100km. The speedo was reading under and the auto transmission decided 6th gear wasnt achievable anymore, acceleration also suffered. After having major failures with other tyres and not wanting to be wondering when the next blowout was going to happen I was keen to have the security and peace in mind that I had good strong tyres on the car and I did and I would have been happy with the trade off, even with the extra road noise. But then with vibrations in the steering wheel I took the car in the get the wheels balanced, they took one look at the front tyres and lectured me about rotating them every 10,000Km, and I was going to but they had only done 7,000Km. Do another wheel alignment, rotate and balance. Still the same noise and reduced economy as expected but was only another 7-8,000Km before I saw the uneven tread wear and steering vibrations. Love the durability and peace of mind that this tyre offers on rough country but if youre doing the big kilometres and value the integrity of your steering, speedometer and fuel economy then maybe this isnt the right choice.
Excellent traction on rd rock & very good in mud, excellent puncher resistance.....but – ST MAXX....As a aggressive A/T tyre I have not had an issue with their traction or stopping ability. 15,000km so far & looking like new. 3 wk's 4x4'n in the Victorian High country not 1 flat. Despite being vrey close to GVM with everything for 3wk's on board. BUT my diesel consumption is MASSIVE now from day 1 fitting them. Mikey T A/T taken off… Read more
(needed new) so tried the more aggressive ST Maxx's. My fuel economy has gone from 9.1/9.3 to a massive 12.9/13.7 with 13.7 being gr8 in head winds it's been much higher. Nothing has or was changed b4 or after fitting the Cooper ST Maxx's. If l was running a 70%/ 80% mud terrain that would b understandable. It's the only downside & the question is r u maybe better off with 2 set's 70%/80% mud & a less aggressive A/T ? Unless your happy with the every day loss of fuel economy or just can't have 2 set's of tyres buy with gr8 conference. I will b fitting tamer A/T's & saving these for our 4x4 camping trips.

Great tyres 265/70/17 St Maxx – My wife and I travelled 21,000 kms on some of the toughest remote roads around the top end of Australia towing our 2 Tonne offroad caravan. WE DID NOT GET 1 PUNCTURE in 6 months. Rotated the tyres and had a wheel alignment in Cooktown after 10,000 km and regardless if we travelled on flood covered roads, gravel, sand or bitumen I always felt confident. These are good tyres for proper, offroad driving. I'll be buying these tyres again Show details
Excellent tyres – Road noise is not even in this equation. I've had all-terrains and mud-terrains and these are almost like a normal highway tyre for noise. Upgraded from AT3's which gave 90,000kms+ usage. I had a few sidewall and tread punctures having taken them to places that most wouldn't. Upgraded due to armor-tek technology. Cooper tyres do cost more but I believe getting 90K+ in kms is the value Show details
Great off road tyre – Very little road noise, extremely good in wet weather, wear very well for a semi mud terrain tyre, tough as nails sidewalls. Over 40,000kms on some very ordinary roads and no punctures yet! Definitely the best tyres I have had by far. Hankook ATM’s previous to these lasted 30,000km and at least 20 punctures in that time. Would definitely… Read more
recommend, I was told coppers had dubious carcass construction before buying, but I got 80000km+ from AT3’s on a previous vehicle. Glad I made the change to the St’s

Noisy and shake cooper ST Max – Just picked up a 2019 BT 50 with Cooper Tyres ST Maxm on them. I drove it from Melbourne to Adelaide- the steering shake and noise was ridiculously load - Any tips on what to do - I think my teeth have fallen out Show details
There are better options – Had a few sets of these tyres on work utes. Had consistent issues with tread wearing uneven (scalloping) even with consistent rotations. Also had many sidewall failures (blowouts) on the highway. Show details
Long lasting but noisy on the road when unevenly worn – Unfortunately I can't comment on the longevity as I'm unsure when the previous owner bought them. What I can say is that they have lasted well in the time that I have had them but although I have had them regularly rotated every service they have worn unevenly and make a lot of noise on the road. We drove from adelaide to gold coast and back and I… Read more
believe this is when the uneven wearing occured. Being a hard tyre I've also noticed they can be a little slippery in the wet, but mostly before they warm up. I probably wouldn't buy them again but only due to the noise from the uneven wearing. I previously had cooper AT3 which I was very happy with.

200 series landcruiser – 2nd set i've had on my 200 series dont mind them, cant really compare them to anything else as have only had the original set on it. And different tyres on different vehicles is not a fair comparison e.g. i have had various patrols, other landcruisers and dmaxs, chalk and cheese. I don't think they are noisy, they do possibly wear uneven so you… Read more
do need to get them rotated and balanced. Don't have a problem driving on sand but like I said no other tyre to really compare them against on this vehicle. I liked the look of the more aggressive pattern. BUT I will say the Cooper warranty is crap got 50 000kms out of last set even though warranty was 70k, might have got another 10k out of them but dont like running my tyres that low. Would I buy another set 50,50 I will do some more research prior
Very Noisy – They have great handling characteristics but I can't believe how much drone these tyres produce at any speed. I have had extremely aggressive mud terrains that don't produce as much road noise as these. I really can't see me buying these again. Show details
Best tyres Ive ever had – I bought a brand new Hilux in late 2011 and requested these tyres be fitted when I collect my new car. I got a wheel alignment done a couple months later when I got a lift kit put on my car. In the eight years I rotated the 4 tyres every 5000km religiously but never got them balanced and never had my wheel alignment checked again. I was even… Read more
slack and checked the tyre pressures one or twice a year. I have been off road and towed a caravan and apart from one screw going into my tyre and getting a very slow puncture once (which I fixed with a puncture repair kit from ARB) Ive had no issues at all with these tyres. Ive so far travelled 170,000km and they are starting to get low but I think I should be able to get another 10,000km out of them before they need replacing. I think I will upgrade my car before I replace the tyres. Ive never had any tyres that have lasted this long on any of my vehicles.
Great off-road tyre but – I always used Cooper St’s on my 80 series with no problems or any punctures then fitted 285/70-17 to my 200 series. As usual the handling was terrific both on and off road and they are the best for beach driving. I let the tyres down to 18psi for beach use and this in turn is causing the sidewalls to split right where the sidewall and tread… Read more
join. I haven’t had a blow out or any punctures but it makes me very uneasy to be driving at 110km/hr with split tyres. 2 have been replaced under warranty and I now have another 4 to be replaced. Not sure if I want to fit these again as I do a lot of remote beach driving on the south coast to go fishing and need a good reliable tyre to get me there and back. I know people will say pressures to low etc but this is what 4WD tyres need to handle.
Noisey as ! – 40 thousand km and noisey as, blocks wear uneven, and its not the wheel alignment, not happy at all ! I wouldnt fit these if they were free ! ,id like to know how long thet are suppost to last ! Show details
Noisy and Uneven wear – Fitted to PxII Ranger from new and have to rotate these tyres every 5,000kms to even the wear out but road noise and fuel consumption still high. Happened to drive Ranger Raptor with BFG KO2's and couldn't believe how quiet they were.....last pair of Coopers for me. Show details
the strong existence – The sound of the tyre will be flooded by wind noise, which is relatively obvious compared with the suburban and urban expressway tire noise. The start is slightly sluggish but the brakes, handling performance and mute effect are very strong. The normal urban area certainly increases, the pattern design is relatively rough, the strong existence. Show details
Cooper Tyres – We run Coopers on all fleet vehicles - ST Maxx, AT and a few more 'road-bias' tyres for town work 23 Hi-luxes and 6 LandCruisers - all less than 3 yrs old on Toyota lease Cruisers are dual-cab, GVM to 3800 with lift kits etc for remote Survey bush work Long distance travel - then into bush with no roads doing reconnaisance and exploration work … Read more
Drivers are comptent and experienced in this work - most 15yrs + remote work
Tyres showed a number of issues on about 20% of all vehciles esp. Cruisers.
From scalloping, unequal wear patterns to instability in a straight line and a sensation of tucking when cornering on highway
Checked and repaired all possible mechanical issues - suspension quality, alignment and pressures.
No change to behaviour
Changed tyres on one vehicle to another and the poor handling and instability now appeared on the second vehicle (!) Tyres still brand new - less than 20k
Cooper tyres supplier tested vehicles and tyres and refused to replace tyres (even though they could reproduce the problems)
During this time the supplier suggested we run the 3800GVM vehicles at a lower tyre pressure (50 psi vs 70psi) than the specification on the side of the tyre. - so it may have been made worse by the supplier being not competent as well.
Please - Read the tyre labels - some specify a loaded pressure up to 80psi for the max. loads (1250kg)
Suggested the following 'Warranty process' - send tyres to Cooper USA - they would inspect and eplace if necessary - otherwise we have just bought a new set to replace !
We do not use Coopers any more due to the quality control issues from tyre batch to to tyre batch
If you get a good one they are fine - if you get a bad one they are not
Fleet now uses Pirelli and Bridgestone for more consistent quality and fewer tyre failures
So much for warranty – I have run Coopers one my LC and camper for 12+ years the latest being ST Maxx, I have had a problem with one tyre, it split inside the rim along the bead for a distance of about 400 mm with splits running up the side wall after returning it to the dealer the agent for Coopers said "This tyre has classic signs of impact damage due to under… Read more
inflation with excessive load" he went on to state he had concerns the other rear tyre will be damaged as well. Not once did he talk to me and ask any questions, when I rang Coopers I was told this is the final decision, when I asked what do they deem under inflation I could not get an answer. I asked is there any way I can appeal this and the answer was no. The other rear tyre is in perfect condition, it has never been loaded near the load rated weight of the tyre always run at a pressure and speed suited to the conditions. Cooper Tyres have lost me.

Exceptional performance and value – I have achieved 125,000klm and have an estimated 20 - 25k left on them I love at rover heads the departure point for Fraser Island I spend a lot of time there fishing now I'm retired. I have made 2 trips to Darwin have had no punctures, or differential problems. Show details
Who said they were noisy? – I had decided on the ST Maxx based on some personal recommendations and the reviews posted but I had expected to have to tolerate some additional road noise. Even putting aside the fact that it’s a 76 Series Landcruiser I couldn’t hear any road noise and definitely less than my previous tyres. Was thrilled to bits about that! Yet to test them in the mud but plans are on the kitchen table for that! Show details
Perfect off road tyre – Had these fitted in LT245/75r16 size in Alice Springs in 2016. Did roughly 60 000km on them between Kalumburu and Townsville, approximately 20 000km of that was on dirt. Still roughly 30% tread left so they are going on my trailer. Out of five I had one randomly blow out at highway speed, other than low pressure the cooper dealer in Alice… Read more
wasn't able to offer me any other explanation or warranty claim (I was running 33psi, most LT tyres need a minimum of 35psi)
Pros
-Amazing puncture resistance.
-Great grip in rocks, mud and gravel.
- Softer ride on corrugated dirt than bitumen.
Cons
-Once they hit 50-40% tread they rode like rocks irrespective of pressure.
-Warranty is nonsense
-Wet grip on bitumen was a bit scary, slid out on a tight bend at 25km/h, it was signposted as 30km/h.
Conclusion
These tyres were great at the time as I was driving alot offroad. However I did not repurchase them as they are simply too expensive compared to other premium brands like Yokahama, Toyo or even BFG.
In Alice Springs I purchased 6x toyo OPAT2 tyres (LT275/70r16) for $100 more than the price of 4x Cooper stmaxx tyres (LT245/75r16).
Excellent so far – These tyres are great on road so far, I haven't been off road yet with them. Comparing the tread pattern and look, road noise is far less than many other A/T tyres. Good grip on wet surface as well. I have done 5,500 kms in 4 months and happy to give 5 stars now. Show details
Great tyres! – I've had these tyres on my car since new 38000km they would have at least another 50k in them, excellent road and off road handling and feedback. Pressure, rotation and wheel alignment are critical with these tyres as they are a bit less forgiving in that department and heel and toe quite rapidly. Show details
Very heavy duty tyres – We're very happy buying these set of tyres because we've always bought coopers because they last longer than other brands we've had before. This time we got these as we're planning on longer trips via mud roads and thought it could handle it. They feel really nice on normal roads Show details
So far so good – Fitted these tyres with a little uncertainty but after 50k travelled with plenty of life left and no issues I am confident in my purchase, they have handled plenty black top, plenty of rocky roads towing the camper trailer, they have been rotated every 10k and balanced probably 2 times in the 50k. they seem to be wearing even, Fairly noisy but going from the Dunlop’s fitted from factory you’d be mad to think they would be as quite.

I would not buy a cooper tyre again – I have had cooper tyres for years I was using the ATR tyres went every where with them up to the Gib river place most people wouldn't go on stations and every where that was hard to get to .All through the Kimberly finding fishing spots I work up there so good to go and new spots.and I have taken it to dirk hartog island about 10 times you have go… Read more
steep point to get the barge across to then island hard core driving not for the faint hearted very rough on your 4wd my cooper ATR tyres went every where with no flat tyers to they were bald so got the ST/MAXX tyres what are disipointment went to dirk hartog island went steep point to catch the barge across to the didn't even get half through to and got a stacked tyre in the side wall in the armour tech not happy took it back to the dealer and they no warienty on a stacked tyre so had to buy another one witch aren't cheap and then back to dirk hartog island and got another stacked tyre in same place as the other one these trips are father son trips not happy these S/T MAXX with Amour tech side walls are the weakest tyres I have ever bought I won't ever buy a cooper tyre again they lost they way and buy the way the dealer has the last say on the warienty so I guess cooper tyre wouldn't have clue how tyre are not a happy customer .
Good off road, but highway performance not so great – I have run these tyres for about 30000kms on my Amarok before removing them and moving them to my off-road camper. The off-road performance on all surfaces is good and they air down well on soft sand. They are very durable and I have only suffered one puncture. However, their on-road performance is not so great. Comparing these to the… Read more
BFGoodrich KM2 which I now run, the coopers provide a harsher ride, poorer steering feedback and less precise handling (and the KM2s are probably better off-road as well). But the real killer for me was the Cooper's highway tyre noise which has an irritating combination of rumble (like diff noise) and whine which only seems to get worse with age.
Reliable tyres – I've had the tyres for about 12 months now and done over 10,000kms in various conditions. No issues at all. Traction is great on and off the road and the noise level is minimal. Comes with an 80k warranty providing you rotate every 10k which is great. I would definitely re-purchase these. Show details
Great wheels – I purchased these tires 12 months ago and they still seem like new. Durable and comfortable driving in my SUV. Grippy in the wet and have been a lifesaver on one occasion. Would definitely purchase these again as they outlast any other brand I’ve used in the past. Totally like be Cooper types. Show details
Cooper Tyres Superior – I've used most of the major manufacturers off road brands, having lived in the Kimberley and Arnhem Land for the past 8 years driving on 90% gravel, rock, sand and mud, I have found that Cooper STT Pro and ST Maxx to be just a better tyre all round. The Gibb River road is hard on tyres, the evidence is visible for all to see, yet the Coopers that… Read more
we ran, not once let us down. I will continue to use Coopers Tyres on all of our vehicles, Highly recommended.
So bad – Got these on jb gator van done maybe 15/20000 km can’t believe how bad there worn Show details
