I have a set of 22-12-9 rear and 23-8-13 front tires I would like to put on my warrior 350. I was wondering if this is at all possible, ive been told there would be an issue with back spacing and proper bolt pattern with a 12" rim and my bike model. If anyone could provide some clarity that would be appreciated.

Cheers.

 

22-12-9 tires on the factory 9" rear wheels should work just fine. Unless you meant 22-9-12 that probably will not work. The 12" bolt pattern is probably different.

23-8-(12?) will work if the bolt pattern is the same on the wheel. I'm not 100% sure but i don't know if the bolt pattern for Yamaha front 12" wheels are the same as the Warrior. I would guess they are not the same. I'm sure it would have been done already if it worked that easy, and I've never seen it done before.

22-12-9 on the rear and 23-8-10 on the front will work with the factory wheels.

 

an mx rim is 8", usual (on everything ive got at least) is a 9" rim. Usual rear tire size is anywhere from 18-20, or even 20-22.
Front, ive never seen tire size exceed 22".. wait.. once i saw a 400ex with 23" mudlites.

Not going to look the best i'd say.

Heres a bolt pattern chart for all your needs
