Simple Tire. I am really impressed with their knowledge and service.
Bought about two to four sets per year from TR over many years, but after now being told by a representative that a tire is still new (and can be sold as such) up to four years after being made, I lost faith in them.
When I asked the rep if she would be comfortable taking her family up to 160 mph on my seven year old tires (bought there) she wouldn't answer. And that's after claiming that my tires would be just fine up to 10 years old.
It's extra odd when their parent company, Discount Tire, won't work on tires over 6 years old. That doesn't bother me since I do my own tire work, but since I never wear tires out - instead they age out - giving up 2-4 years of useable life would bother me a lot.
