Tires are on a car that I drive on average 80-90mph on the highway every time I'm on it. The car was bought used with 44k mi and I now have 65k mi with the same tires on the car. I don't know how many miles were on the tires before I bought it so there could be more! I do know this: These are LRR grand touring tires but perform like high performance tires. I've got at least another 10k mi. before I MIGHT have to change them out. In the snow, I only slid in slush because I was testing it's performance. In the rain, I can consistantly take off ramp curves at 50mph without drama. They've only recently once acted like they wanted to hydroplane while I was doing 85mph in a downpour. Slowing down stopped that. I did have an issue with air escaping one of the tires but filling the tires with N2 solved that. I take turns consistently around 35mph in the city and I don't have a problem with grip, even when city streets are wet. This (and any tire's) performance is greatly affected by incorrect tire pressure. They were squealing when cornering for a couple of days after I left the shop and checking my tire pressure, I found the dealer pumped up my psi. Reducing it to the correct pressure eliminated that. Last week to S. Carolina, they stuck firmly to the road as I was doing 90mph through the curves of W. Virginia and when I had to swerve (not careen) around a pail rolling around in the road.
I don't understand the bad experiences that other people have with this tire. This is an excellent tire....if you take care of it! You have to rotate your tires. You have to balance your tires. You have to check your psi on all your tires. Don't mislead others just because you roll around with 20 psi in your unbalanced tires that haven't been rotated in 10,000 miles and complain about premature wear, excessive road noise, soft sidewalls, or a blowout. Thats not a poor, faulty tire. That's a poor faulty operator.
