So the 4.56" backspacing will fit with the 33's nice
what would it take for 35's as a minimum?

 

I had to use an 8 inch wide wheel with 5 1/2 inches of backspacing, this allows the wheel and tire assy to stick out only 1/2" more than stock and gives you more clearance in the front where most of the rubbing with large tires tales place. This applies to 17 & 18" wheels. With 20x10 wheels with 35" mud grapplers you will probably need a suspension lift.

 

Yep, at least a 6 inch lift.

 

I put a 35's on a 20x9 with 5.71 bs and still had to do some cuttin. Like pawpaw said its mainly for looks. I wouldnt dare do any heavy offroadin without a lift.

 

@pawpaw

I'm looking at the same kind of setup, did you have to cut a lot to get rid of the rubbin'?

 

What about 18x9 with a +18 offset 5.71 backspace, or +30 offset 6.18 backspace. Could i fit some BFG AT KO's in 305/65/18, 325/65/18, or 325/60/18 on either of these wheels with a 2.5 inch leveling kit?

 

I think you would be Ok with the 18x9 w/6.18 BS to run the 305x65 or 325x60's the 325x65's would probably rub real bad. The 305's are a little taller 34" as opposed to the 325x60's which are 33 inches tall but wider. Either way the truck would look great. Check with Wandell on this one!

 

When I had these tires on my 9" wheels I had to do some minor trimming on the lower wheelwells and they still rubbed a little. I put the tires on some 8" wheels (which I should have done at first) and they clear easily, probably could have gotten by with no trimming.

 

I agree with Paw Paw. A 325/65-18 is basically a 35x13.00 tire. You would have serious rubbing issues.

 

Ok, thanks guys. I'll cancel out the 325/65/18 as an option.

 

thx a lot for the info
