How old is this tire?

That great. you buy some MT steamroller tires for your open wheel T-bucket that gets 6 rides a year and after 60 rides, you end up with $900 worth of 500 mile 'junk' tires that still have the nibs on them. Makes you wanna buy some used NASCAR tires to run...

Rubber doesn't last forever, just the way it goes. Put more miles on your T-bucket or burn more tread off your tires when you drive it, problem solved. :D Beats the crap out of ending up on your lid because you blew out one of those old steamrollers 'cause of dry rot.
