Anyone know what it will take to run the 35s on a 37 package? I assume everything will fit. Issue is offroading in the winter and don't really want to keep changing back and forth between tire sets. Looking at Nokian Hakkapelitta LT2 LT315/70R17 for the mountains. Issue is they really don't make winter tires for 37s. I have an extra set of raptor rims that I would just swap for the summer. I would appreciate it if the speedo was correct. Anyone know if I would need a programmer and if there is a setting to change rolling diameter?? I also don't appreciate the miles going up faster!
