Maybe I did not explain it correctly, but my tires had plenty of tread left. Plus, I will not exceed 2,000 miles per year in future years, and I was hoping to buy a new SUV, so I don't need a huge amount of tread.
I do understand that the rubber can wear out after a certain number of years, but there are absolutely no signs of aging on my tires, since they have had relatively little exposure to UV rays from the sun (due to low mileage and I park it in my garage). Plus, having nitrogen filled tires (like mine) goes a long way to extending the life of the rubber, because it virtually prevents moisture and oxidation from the inside of the tire.
But I went ahead and dropped $1,070 on a set of 4 Michelin Cross-Climate2 tires at Costco, including 4 new TPMS sensors. Just my luck that Costco is having a $150 off sale on Bridgestone tires this month, and the Michelins don't go on sale until September at Costco (Costco rotates their sale between Bridgestone and Michelin every two months).
Buying new (old stock) tires is not likely these days, as popular tire models are in short supply like everything else. I couldn't even get the Michelin models that I wanted because of supply problems from Michelin. It took several days just to get the Cross-Climate2's.
