March of last year I had BJ's Wholesale replace my old tires with new BF Goodrich tires. Neither the most expensive nor cheapest tire they sell. I say middle of the road. Anyway, it seems that with under 12,000 driven since the tires have been put on, both rear tires are balding from the inside out while the front tires are perfect. Now, I'll admit I never had them rotated, but still - why such short life?
