AFAIK, all KK models come stock with TPMS sensors in place, so you will need to either arrange a workaround (LOST JEEPS • View topic - "Trick" The TPMS
- if there is a prohibition against cross posting to other forums I apologize) or replace your TPMS on the new Steelies. I just walked out and have a feeling that this is probably a moot discussion. After unbolting the wheel and taking a look, I think that it is unlikely that a 15" rim is going to provide enough clearance around the caliper. You MIGHT be able to modify the caliper housing to make it work via a die grinder, but that can result in catastrophic failure if you take off to much or attack the wrong area on the housing. The only real way to check is probably take the KK, throw it in the air and see if the thing will fit. Not fun in the weather I know.
