Thread: Anybody running Cooper S/T?

Am 9,000kms into a set and no worries so far.

Lost count of how many I've heard about. Personally a good friend had two fail on his Prado within a week of buying them both tread separation. On my D2a I had them and they wore very unevenly.

My Tdi Defender also came with 6 new ones fitted and after 12,000km they are wearing very unevenly. A mate's Defender has them and he has torn some tread blocks off on the dirt tracks.

Would I buy them again - No!

The other Coopers AT's, STT's etc all seem to be much better tyres than the S/T's

I doubt. I think they are just a crap tyre. I've been there and wont be going back.

I put a set of 255/70/16's on my p38a about 30k ago. Early on one have a fracture trough the middle of the tread which was unfixable. Impact- they said, no warranty slaim. Then had 4 punctures in the two back tyres and then finally a blowout.(50 mm split in sidewall)
I had replaced both front tyres when the tread fracture occurred(keeping the other side for a spare) but when I had a flat with stone holes through the tread in 2 places at once needing 3 plugs to nearly stop the leak on Saturday and then a blowout on Sunday I decided to get them off, as every time out on gravel I was not sure of getting home again.
So the Rangie now has a set of Goodyear Wrangler m/tr's in 245/75/16.
Shame as the Coopers were nic(er)to drive on but.......
These were not their light truck jobbies but the passenger ones .
But their man in the pamphlet says he's done 60k with no punctures.
So I rekon mine were a bad batch but the importers offered NO support.

Oh Slunnie you wise one.

All tyres have their horror stories, my ute has Bridgestone RE50 or something and at $500 bucks each have failed twice with bubbled side walls, very noisy and they are now 1/2 worn at 3500km's.

Coopers make good tyres just some are better than others, I for one trust mt ATR's fully.

Tried many other brands and find they drive well, wear well and cost not too much.
It could well be a crook batch and I hope they help you out in some way.

Big Guy, i reckon Bridgestone make crap tyres all round, ones on my old VZ commodore ute all bubbled in the wall(2 sets) and were noisy as hell, the ones on my VW transporter are very very unroadworthy at 15,000k (bald), they're just crap

True, but some have more than others and the ST's are just a crap tyre in my opinion, and not through bad luck or misuse, but crap through design.

The ST will not tolerate slip without fracture of the side lugs, the lugs are narrow and tall with a sharp radius in the root. These are paired up to look big, but they are not. As a result they tear side lugs when they encounter slip. Instead of fixing it properly they change the compound to make the rubber more pliable without fracture at the lug root and call it the ST-C The problem of the tread block design still exists in my opinon. Its got nothing to do with crook batches

Add that to a 4WD system that requires wheel spin such as the P38 and the pre MY03 Disco2 and you will damage the tyres.

Add this to the numerous horror stories as you call it of delamination, add these storys to the litigation and whistle blowing that has been happening by their own staff in the US of poor manufacturing practise of the tyres and it is no wonder that Cooper tires are original fitment to NO new vehicles - something that could earn them a hell of a lot of money.

Trust in the ATR's, thats nice but its a very different tyre to the ST.

Bought 5 new for the Disco, 42000ks 2 went egg shaped 1 side wall collapsed 1 side wall punctured not repairable. Rang cooper about there warranty, GUESS WHAT..I live in the NT its out of the warranty area, last time I looked Darwin was a Capital city..

Yep you guessed it NEVER again..
Thats my 2c worth
