I have 56000 and they are about gone on the front. I got it with 40000 so I dont know how often they were rotated. Hopefully they will give me new tires and I can trade them for bigger ones.
Warranty on the tires will only cover defects (ie: blowout). Not wear and tear. So if you show up at 90K miles with bald, yet inflated rotating rubber, that's just normal wear and tear and don't expect free replacements out of it.
Never mind on this. I went to the dealer and asked. Its good for 100,000 miles on the Dunlops that come on it. But the dealership and only the dealership has to rotate the tires every 5000 miles and its good only for the original owner.
