need help deciding which tire size to run.....01 supercrew 9"s of lift on 20x12 -44 offset wheels with 4.75"s of backspacing.... more or less will the 15.5's fit with out rubbing? Its a DD also. and yes its getting re-geared

 

I'm pretty sure 38x15.50's won't fit.

 

I had a toyo open country M/T 38x15.5 on a 18x10 -25 with 4.50 backspacing and had rubbing on the frame but they look much more aggresive then a thinner tire.

 

Just as a point of reference, several members have fit 38x15.50's on 97-01 4x4's by using a 3 inch body lift, cranking the torsion bars all the way up and using a 10 inch wide wheel with 4.5 inches of bs, but they still had some rubbing. I think the 12 inch wide wheel is gonna cause you problems.

 

thats basically my truck and thats exactly what i said....here are your options
1. Let it rub (harder to get into parking spots and maybe not that safe)
2. Use spacer (they add a new vulnerability and I would never)
3. Go with the 13.5

Its your decision!

So out of curiosity what gears?

 

Yukon 4.88s. I have a set Of 18x10s -27 offset not sure on the bs. Maybe those with the 38x13.5's

 

The 18s are -24 offset 4.5 backspace

 

id stick with a 13.5 but you still might rub some
