2012 JKR TPI question
Going to be putting some 35s on a set of stock 17s that I'm getting from a friend. Planning on keeping my stock tires for winter and back up set. The question I have is the set he has came off a 2007 and have no TPI. Can I just mount them up and run them without them with a pro cal? Or would i be better off buying a new set of TPI and if so any good ideas where to pick some up for a reasonable price?
