No, I did not get 90,000 miles from these. Well, I did, that that was five sets of them. I guess you could say I like these tires. In the wide size my car uses, they tend to get a bit skiddish on wet roads. I do NOT want to hit standing water in the road - but that's largely a function of the wide tire size on my car and not necessarily an indication of a poor tire.
If I drive VERY mildly, I can get 33,000 miles from a set. In fact, my first set lasted 33,000. But these days, I drive the car like a sports car and with all the curves in the Smoky Mountains (USA) I get around 15,000 a set. They really do handle the curves well for a mid-priced tire.
My car is a convertible and the best part about these tires is how QUIET they stay. I've ran at least three sets down to slick and they just don't make any noise. There are better tires, but I don't believe I have the driving skill to require better tires - even well above the speed limit on curvy mountain roads. My point: If you are the average driver, these tires will be fine. If you are a bit spirited behind the wheel, try a set. If you are a real pro and drive a sporty car - I'd bet you wo'nt find them to your standards.
