So my question is going from 35's to 37's. Is the main concern the tire weight and then rotational weight change? My reason for asking is I'm about ready to need new meats, currently running Nitto Trail Grapplers in 35x17 and these weigh in around 80lbs, according to their website. New 37's from BFG or Goodyear weigh in around 75lbs. Anything I'm missing in the details? Riding in a Metalcloak lifted '13 JKUR manual with upgraded ball joints and Yeti steering goodies.
