Like the title states. The Mickey Thompson ET Street bias tires. When is it time to replace them? I have had barely any tread showing for quite some time now. Tech has never said anything about them at Cecil. Last month, at the Grove, the tech guy said I need 2/32s, but let me race anyway. So after two days of racing, there is no longer any sign of tread. I guess it's time to buck up for new ones?

How long have you used them? Does 60ft. go away at some point?
