Wheel help please!!!

[gears2]

I have what i believe are the stock wheels on the back with 20x11x8 razrs. if im correct the stock wheels are 8x8 right? what i wanted to do was take these old wheels from a go cart to put some 4-snows on. However, i am not sure these wheels will work. when i measured the wheels, both sets measured 9" od tall. how are they 8" wheels? I am just trying to make sure that they will fit right before i try it. Thanks for any help

Also, is there an off set for the stock wheels?

You have to worry about bolt pattern. You can use a 8",9",or a 10" wheel as long as its the right bolt pattern. The rear is 4/110

from what i understand the bolt pattern is 4/100. I believe 4/110 is a banshee bolt pattern. anyways the wheels bolt right on so i dont have to worry about that. Thanks fo the help
