Looking at Rugged Ridge wheels at (I think) 32 lbs and 285/70/17 Duratracs at 53 lbs. I believe stock rubi wheels are 24 lbs and the tires are 48. Coming from sports car land adding 13 lbs per corner would be unforgivable, but of course I'm not going to be taking my JK on the track. (actually that would be kind of fun). Is the 13 lbs anything I should worry about?
