So I have an 06 fx4 that came stock with 20" wheels and I would like to find someone to trade for their stock 18" wheels. I brought this up to a tech at a local ford dealer and he said that I might have problems with tire pressure monitoring system if I do that. Just wandering if anyone else has had any problems with this system. Can I just swap and not worry or do I need to reprogram the system for the different size wheels or what? He also mentioned something about possible clearance issues with the brakes if I downsize but I don't foresee this as a problem since some of the fx4's come stock with 18's.

 

You will have no problem, since they did not put TPMS sensors onto the F150 until 2007.

 

oh well I didn't think that it did have them but the same guy was telling me that all fords have had them since 04 and they are mounted to the wheel inside the tire and that the newer ones were part of the valve stem

 

just found a chart that proves that that guy didn't know what he was talking about like I suspected. Maybe he thought my truck was an 07 for some reason
