I put these tires on my Tundra X-SP Package truck and had no idea until recently (when I began thinking I needed to look at a new set) that I had 75,000 miles on them. I could probably get more, but I need to hit the road for some trips and just don't want to take a chance. Excellent tires as far as I'm concerned!!
the worst tires I have ever wasted money on, noisy, cannot seem to be balanced. only a few years, low miles and they are dry rotting! really! I got gouged on the price at a Firestone dealer. I will never buy firestone/bridgestone again.
