Just thought I would post my findings.

I fitted a set of Cooper S/T MAXX on the 2011 Troopie. 305/70/16
They replaced a well used set of Cooper Discovourer ST. 285/75/16

Haven't done too many klm's yet, but so far they are impressive.
Spent Easter on the beach at Double Island Point. The ST MAXX's were very impressive in the sand. Far far better than the previous tires.

On 2 occasions I drove out of situations where I know that I definately would have been stuck with the old tires.
1 was in very wet soft / sinking sand assisting a young couple who had drowned their Nissan
The other was in soft deep dry sand trying to salvage a fellow traveller's camper trailer for him.

Have also done some limited klm's on dirt / stones. Again very impressed. Good control & feel at all times.

On-road they are a little twitchy, but I'm thinking that also has a bit to do with the suspension set up.

All in all I'm very impressed & have absolutely no regrets.

Cheers, Bryan

I have a set of S/T MAXX 275/16 on my 99 Troopie as well , my previous tyres were the also ST discoverers.
They are not wearing quite as well as I thought they would. But in saying that I had no trouble at all when I did a 22000 km trip last year ( Simpson Desert included )
They have now done 42000 km and I reckon I have about another 20000 ks or so left.
They are a really good all-round tyre , I have never had any problems with Coopers.

I have Cooper STMaxx on my 2008 79 series. 285 x 75 x 16 Got them brand new for last years trip to the Kimberley and the Canning and did 14000kms. We covered some pretty rough stuff and towed a camper.

I reckon they are at 80% now so I would expect to get another 40000 out of them which means around 50000 out of the set. Thats not what I would call economical but I have had no flats or any other issues, even at quite low pressures. Traction has always been good on all types of surfaces.

To me the compound seems a bit soft which means good traction but not value for money.

I run STT's on our 80 series and they are much the same. Never a problem getting traction but never getting more than about 40 - 50000ks out of a set.

For me, traction is more important than getting 80 - 90000ks and after all the kilometres, never having flat tyres or blowouts makes them worth the bit extra.

I'm happy enough with them to get them again next time.

"Haven't done too many klm's yet, but so far they are impressive."

Any tyre is after the last 10000km on a worn set.

What was the benefit or decision breaker to go 305/70 instead of the usual 285/75...?

Wholehog, I don't agree that any tire is impressive when new. It completely depends on the use.
Since new, the majority of the few thousand klm I've done has been on sand. Not just over Easter as noted in my original post.
How good a tire is on sand depends more on the shape & size of the footprint than depth of tread / age of the tire.

On this basis, and running at the same air pressures, the ST Maxx far outperforms my old tires.

With regard to size. Why is 285 the "usual"????
My previous set was 285, but they were on it when I bought it. I have a personal preference for 305 tires. So when I needed a new set I put 305's on.
In this instance cost was not a deciding factor, although I did get a good deal at a 4x4 show for buying a set of 6.

Hi Byan

Our group have switched over to them a couple of years now and find them the near perfect tyre for when your trip includes some harder tracks.

We probably have a dozen sets now all way up to 35" types.

They are just quiet enough to live with when touring and don't have as much tread gap exposed to spikes as do mud terrains.

From the avove sets I think there have been 2 plugs required , all in all very tough which is our main requirement , so we agree with your assesment.

We do however put on less tough tyres as soon as we get back to city as we like to keep the tougher tyres as fresh as possible for when they are needed.

We live on the Great Central Rd 230km west of Uluru. This is our second set of STMaxx. First set we got 50,000km out of with out any problem.

Love them recommend them for out here but did anyone else notice a big increase in fuel consumption when you put them on?

Note we did not change tyre size?

Was the tyre before a less aggressive pattern?
