yeah thats on the to do list a couple years from now. i got to thinking and im gonna do everything BUT the 37s this year. cause ive only had these 35s not even a year ill had them a year in august and i only have like maybe 6k miles on them and thats pushing it i know ive gotten my oil changed twice and i didnt change it right at 3k miles both i went way ahead one time so i should have less than 6k miles on them. no reason to get new tires when i spent 460 a piece last year i believe.
