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
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 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

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 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 patte...rn. 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

The warranty mileage is a marketing fantasy.
So I've been running Coopers ST Max on my 70 land cruiser and the tires have 80,000 km warranty, I've done 50,000klm on them and they are almost completely worn out. I have not undertaken demanding four-wheel-drive driving and my four-wheel-drive is not especially heavy. This is the third set of cooper tyres that have not met warranty. They have performed quite well, but given the premium price you expect them to last as advertised.
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 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 a...nd 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.
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.

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 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 p...

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 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 no...t 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.

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 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...

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 !
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.

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 (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.

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.

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 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 fin...al 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.
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!
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 wasn't able to offer me any other explanation or warranty claim (I was running 33psi, most LT tyres need a minimum of 35psi)
-Amazing puncture resistance.
-Great grip in rocks, mud and gravel.
- Softer ride on corrugated dirt than bitumen.
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.
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.
Questions & Answers
Can I fit 315/75 16 to an 8 inch rim
Currently have 285/75 16 fitted to 8 inch rim
Hey guys I have got the cooper st/maxx tyres put on my 2018 hilux, I seem to get a lot of vibration in the Ute, through the whole cab, seats and everything, when driving on rougher sealed roads, haven’t taken it off road or on gravel as yet but I’d imagine it would do much the same if not worse, I haven’t taken it back into the shop yet, just thought I’d ask your opinions first! any ideas? thanks in advance
I would be straight back to the shop, it sounds like a balance or alignment issue. Do a good visual check on all tyres to be sure they are identical specifications and there are no tread defects.
I'm assuming all the basics are checked or attended to by the tyre fitter/supplier
Ie Each wheel balanced and alignment all good at time of fitment - and that the vibration has occurred only after the Coopers went on?
Not too sure what your original tyres were but some of the newer HiLuxes we have seen have come standard with a road-bias tyre which run quietly and smoothly on bitumen. The ST Maxx is quite a blocky thing and will run noisy and a bit viby on bitumen, but not to the extent that it intrudes into the cab.
If you can't cover the noise by turning the radio up (hahaha) then it sounds like you have a greater problem than that
If you have access to an old set of tyres (still legal tread but on the way out) swap the Coopers out and see if the vibes stop
Unfortunately, if you do find that the Coopers are the source of the problem you then enter the world of despair that is the Coopers "Warranty Process"
Unless you have a really good supplier - or a lot of time and money to spend pursuing an American Company internationally - then you are pretty much doomed
If you can make it more expensive for Coopers to ignore you than it is to replace the tyres (or refund your money !!!) they may act in your favour
To this point I do not know anyone who has had successful Cooper-factory warranty replacement
The 'Warranty' replacement is usually provided by the local supplier (often at his own expense) so HE doesn't get a bad name for supplying tyres that have failed or have been faulty at time of supply
I do know suppliers who will no longer stock Coopers - in Brisbane,Townsville, Mackay, Rocky, Blackall, Longreach - citing that as one of the reasons
Coopers make more consistent quality TV ads than they do tyres
