Has anyone tried or know what the new cooper STT mud tyres are like. Need new tyres and was going to get new BFG muds but saw the new cooper tyres and want to know if they are any good.

Have the old cooper tyres on at the moment but think I will go back to BFG's unless the new cooper are really good.

Fixed too many puncture of late....looking at new tyres as the old ones (Toyo Opats)are buggered/wrecked/patched, all have tubes etc.

That's why I also am interested in the NEW Cooper STT's. These are the ones touted to be stronger (3 ply) in the sidewalls, new design tread pattern, etc.

I drive 50 % bitumen; 45 % rough dirt roads/station tracks/no roads/gibbers/stony deserts; 5 % sand at Robe.

Standard 16 " Nissan GU steel rims 8 JJ, running 265/75/R 16's.

Reason I am particularly interested is the resistance to puncturing walls. I note that BFG M/T and Goodyear Wrangler MT/R both also feature a 3 ply wall. If all are 3 ply walls, LT rated and 10 ply, at any given pressure - say 28 psi @ 80 kph with 3.3 t load - which is the favoured tyre?

Why?

Cheers

Rick

The STT is SOFT.
If lasting is an issue go BF's over the Coopers. if $ doesnt matter go some AT's for road, and some Simex's for offroad.

Then again, go the MTR over BF or Coop

Bruce, what's your experience with MT/R's versus the BFG muddies?

They do appear to be about $ 40 each cheaper than the new Coopers, but similar to the BFG's in price per tyre fitted.

Cheers

Rick

PS. one set will have to doo me. Only use the black top to get out of town.

I have run both BF's and MTRs in 33x12.5x15s on my GQ... But the BFs were the OLD style.

I like em both, but I dont think you can fault the MTRs great reputation anywhere you look.

On road or offroad you will have issues faulting either. Some say that the BF is better in mud, but I've had no issues.

I find that with any MT they get loud with 50% worn klms on them... Plenty of photos of MTRs and BFG in action on my page. The MTRs like to be balanced regularly, but not out of the ordinary.

The KM Series BF, when they came out had a bad reputation with the new soft compound. BF's had a magic rep for lasting ~80-100k kms etc. But with the soft compound, they were losing klms, and having some issues with sidewalls, with one bloke in the club having 1 BFG MT die on first trip, as others would have had with Coopers (one bloke had 5 flats - 2 at once as well on 1 long weekend trip and let the Coopers rep know this at a club meeting where he gave a talk!), BF, MTR, Swampers, etc etc. it can be luck of the draw.

My BFGs are on one of this forums trucks still to today! Royce's 75 series bus.

I'm plannin on selling the MTR's when I get work, and will get them again since I can get BF or MTR for same price. I have prices on both in 33's for $270ea f&B from Tirepower Blackburn Vic.

Have you looked into the 10ply Coopers I think they are?

Yeah, looked at the new Coopers in 10 ply. They want $ 318 - all three places I asked are the same price, so this tells me no competition exists on them yet, they are all quoting RRP.

can get the MT/R's for $ 279 in 265/75 R 16, which must be very close to 33"

Thanks for the detailed feedback on the MT/R's & BFG muddies.

Mud is not something I drive in - Geez, it's bloody dry over here in South Oz at the moment. Still, it always rains after a long dry spell.

Cheers,

Has anyone mentioned that 28 psi is ridiculously low and asks for all manner of problems ?? Suggest 40 psi as a starter if you really are serious about careing for your tyres ..IMHO...!!!

Hound,

Although the new STT tyres are is very short supply I do have a set of 285/75/16 muddies.

Most of the driving has been on the black top and one trip to the Vic High Country.90% black top 10% dirt for the fist 5500klm.I have only had them since the 1st of April. The next 2 months will test them out with a Canning and a Simpson trip back to back.

So far I have found them to be as quite as the BFG muddies that I was running and in the VHC I had no problem with traction. Wheel spin is not a problem from the lights( after all it is a Troopie) and the handling and tracking are also not a issue.

There was a small amount of chipping after the VHC but I put that down to the fact that the tyre were getting a real work out from the Troopie because of the hard suspension and weight of the vehicle. With the hard suspension the tyre have to flex and work a lot harder to maintain grip.

With only 5500klm it is still a bit early to say how long they will last and how many punctures they will get but I will keep the Forum up to date.
