xfactor-- i have tried a lot of rim and slip-on combinations over the years, mainly on boxstock cars but also on magnet car class cars with poly , ceramic and neo magnets.
There are a number of rims and tire combinations that are out there that can handle most classes.
I have tried These Rims: Quicker wide, Slottech narrow, BSRT wide and narrow, Wizzard wide and ultra narrows,JW wide and narrow, Aj's.
I have tried these tires: Supertires, Slottech, Wizzard,Aj's,Ballsout racing, Jw's.
The best are the tire and rim combo that gives you the right size, firmness and traction for the car and track you will be running on. There are endless combinations that can be tried. Rim size alone will allow various od's to be found, but the Id matters. My suggestion would be to start with the car you are using. Do you need Narrow rims to fit the car? If so your life just got easier. You have the Slottech with 4 rim sizes and the Bsrt with 4 or 5. Also Quicker is coming out with narrows this week. The wiz Ultra narrow need tires to be cut for most sizes so if you are up for it try em. I woud reccomend starting with the Slottech's or the BSRT because the tire and sizing are systemized and both are high Quality. Check em out on their respective websites and try the sizes that fit the car and class.
