A few months ago one of the Mopar Magazines had an article regarding date codes and how to read them etc. Most of the shows I attend, the majority of the guys are running Goodyear Eagle GT II's, Goodyear Nascar, Eagle II's with the eagle head logo,and even the Goodyear nascar with the yellow letters. I'm sure most of these are outdated 5-10 years ago and we are limited to the BFG or Cooper Cobra in a 14 or 15" tire. Are you guys relying on the mileage on the tires instead of the age and is this safe?
