I was getting the Mini's annual check-up, oil change, etc., when the Mini dealer asked me if I'd like to go ahead and replace 4 tires. His exact words were, It's time for your third set of tires. The car at the time had about 39k on it, and it was my first set - the garage manager was stunned. He didn't believe me asking again if I had every changed the tires - no. This is the first set and they have life left in them. I bought my own torque wrench and socket and rotate them myself about every 5k or so. Frankly it makes it easier to clean the wheels. Driving for us is average around town with about 4 or 5 1,500 mile highway trips tossed in. We don't drive agressively and don't do curvey roads more than usual. ONE NOTE: One of the tires has suffered three flats, all puncture wounds, all debris from road including one object that was literally 1/4 square. All three times I was able to have tired repaired with no issues. here's the kicker - all three punctures were within 5 inches of each other on the SAME tire over about 15 months' time. I wish my luck were that good on the lottery.
It's now time to buy again and my wife said, Why wouldn't you buy these tires? I guess that settles it. I'm very pleased.
