I actually had an agruement yesterday with a shop owner here in CA trying to sell me a used set up.
When I told him 8 yr old tires are useless on a Viper rubber gets hard and traction is lost.His response was "thats not true... thats what people on forums say who don't know anything about tires.These tires are fine"
Worse part is when I called before going to look at them he told me they were made in jan of 08.Thats not what the stamp date says
Was a well known shop in San Jose who does alot of celebs in the area.
