Bigger front than back on a dually?

pikeman16 · 08-15-2008, 12:16 AM

Would it be possible to run a bigger tire up front on dually width wise than on the back? I think someone said you can run a 255/85/R16 on the rear without needing a spacer, and i did the conversion and that comes out to be a 33x10" tire (give or take a minor amount). Now could you run a 33 by say 12.5" in front with those? or would it not work or just look stupid? I'm kinda trying to avoid having tires that stick out absurd amounts on the rear fenders but still be decently tall tires

I don't see a problem as long as the tires are the same height, otherwise it will mess with the gear ratios if a 4X4.

As long as diameters are the same.

i knew the height had to be the same just wasn't sure if the diameter being different would screw with it. whats the biggest tire they make in a 10 or 10.5" width?

deepstep · 08-24-2008, 07:58 PM

are your wheels all 6"? or are you widening the fronts?

a question i would ask is:
would running different size tires mess with the ABS?

if it's 2wd there should be no problem, if it's 4x4 your OD needs to match front and back
