Hey all - anyone else mounting their own tires? This was my first time doing anything remotely low-profile: 285/35r19 and 295/30r19 onto '12 NISMO rims. I figured out right away that without something to push and hold the bead into the wheel's drop center I was going precisely nowhere.
I wasn't happy with the cheap/brittle looking plastic solutions I saw online, and wasn't particularly in the mood to dish out a bunch of money. My BeadBuster couldn't push the tire down quite far enough on these wheels, either. So a little bit of CAD time, waiting for the printer to do its magic, and I was on my way. Works *amazingly* well!
I'm likely going to make a few changes to make it quicker to print, but the dimensions are spot on (at least for the NISMO wheels...). The printed threads turn smoothly enough, though I need to drop the size on the 19mm hex head on the bolt just a hair to give some clearance in and out of the socket.
