I just had a brain cramp and bought tires in NJ w/o checking the date code. It was disclosed to me they were taken off an '08 Sky with under 1K, so I should have done the math. Tires visually look brand new. Got home and discovered they're 8 years old. Mr. Tire is making me sign a liability waiver before they'll mount them, saying they don't recommend I put them on the Coupe, based on age alone. They agree the tires look fine. Am I crazy to mount them on the GXP?
