I've got the Cooper S/T 255/70*16. Not by my choice, they came with the vehicle. They've done about 65,000 so far. Look like they might go another 20-30,000km. I just put 2x new fronts on as previous owner didn't do a wheel alignment and 1x was feathered bad on the outer edge (although, we've done about 13,000km with it like that since we purchased the disco - doesn't appear to have worn much in that time ... with a wheel alignment too). Put the other old front on as a spare (and retired the never used Michelin XPC).
The Coopers have no signs of puncture repair. The sidewalls are holding up well (I air them down to 16-18psi regularly as we live at Stockton Beach, and run them 33/38 on the road), and there are no torn lugs on them. I've only done a small amount of rocky offroad with them ...
... although this sunday might see them get a real workout :eek:
I'm not a tyre expert, but so far I'm pretty happy with them. Not to noisy on road, still agressive enough off-road for what we do, seem OK in the sand. Haven't given them a real mud workout yet, but I'd expect them to do OK.
fwiw
Kev..
