just bought my new rear tires today and hoping to get them on saturday if i get off work in time...im going from a 275/60/15 to a 255/60/15...so im hoping to pick up a little bit of a gear because there 1" smaller in diameter and about 10 pounds lighter a tire so that will be close to 20 pounds of less rotation mass or what ever, want be alot but every little bit helps..cant wait:beers:

does anybody have pics of a 67/68 or 69 with 15x8 and 255/60/15 on the rear ? and skinnies in the front ?
or maybe even a 275/50/15.....i might try that next year because its a 26" tire..
