How big of a tire can I fit on my stock rim before I need to go out and get new rims. I like the way my rims look, but for my next tires I want 33 x 12.5. I am assuming I will prob have to get new rims. Is that the case?
You can use the stock rims with a 12.5" tire if it's an 8" rim. If you favor the stock rims, chances are they'll cause the tire to rub. Wheel spacers will correct that.
They could be 7" or 8" rims, take one off and it should be labeled on the backside of the wheel spokes.
Chances are the tires will rub the spring buckets in the rear as the stock wheels have too much backspacing. 1" wheel spacers all the way around should do the trick.
I checked and they are stock 15 X 7 steel rims. I know I will probably have to use a 1" wheel spacer, but what I am worried about is the width of the tire I can run on that size rim.
