wondering last time i ran my truck on stock tires 275/60/17, i think 30in diameter. now am gonna go with 275/55/16, that's a 28 in diameter plus drag radials. i was just wondering if this would helping or kill me. let me know what yall think. 12.90s on nitrous. but after i got it tuned by Flaco it hit a 13.4 on motor. Friday i should have new times on motor and nitrous.thanks
