Thanks for these website links. The tsmmfg.net looks like they may be able to help. On the websites I've checked, the disc brake conversion all state 16" wheels or larger. I bought my truck last fall and it's running P235175R15 tires. These are the old split rim wheels. The rims are in nice shape and painted to match the detailing of my truck. I'm sure there's plenty advice on rim sizes within this forum. I was hoping I might find a disc brake solution and not have to change my wheel size.
