Need help with wheels and tires

SCWALKER0104 · Aug 13, 2012

I'm putting a 3 1/2" lift with 2" body lift On a 1975 bronco what is the best wheels and tire combo that will fit. I'm looking at 33x12.5x18 tire with a 18x9 wheel that has +19mm offset and a 5.5 back spacing. Guy told me it would not fit.. Please help. Really want the 33x12.5 tire to fit. Would a rim with a -12mm let the tires fit. Thanks....

Did he say why they wouldn't fit? It could be the center hole isn't big enough for the hub. If so no amount of backspace will fix that.

To be honest I can't remember those metric offset numbers today. Is a positive number a deeper offset so the wheel sits further under the vehicle, or is it that much wider then having the mounting surface centered in the wheel width. I know it is one of those two but I forget which way it goes.

That looks like around 5.75 backspacing. So the back edge of your rim is 5.75 inches from the face of your hub. That is a lot for a vehicle that has radius arms. Not sure if someone else has a better answer but 3.75 seems to be the max on a bronco. On a 9 inch rim that would be -32mm offset

With a 18 inch rim they should fit however you may scrub the radius arms on lock. I run 18x10 with a 4.5 bs
