Offset and Backspacing Help?

Jdogg · 02-12-2008, 01:33 PM

want to add some aftermarket wheels and tires to my 2008 2500 megacab 6.7. I will add a leveling kit, 33" tires and need to know what kind of offset and backspacing do I need to look for so tires/wheels don't stick out? .5-1" is fine sticking out but don't want too much...thanks

Any rim with 5-1/2" to 6" would give you that. Any thing less than 5-1/2" say like 4-1/2" will stick out a good bit. I have 4-1/2" on my truck now with 1-3/4" flares and mine stick out past the flares.

Here you go

The tread of the tire is even with the edge of the flare and the sidewall sticks out past the flare about a inch or so.

stock wheels wont stick out
zero offset
side note: you can clear 35"s on that truck no problem
