I have a 05 F-150 4x4 with a 2.5" leveling kit on and I am about to order some new tires and wheels. I need to know if this setup will workthat I am going with

Toyo 33x12.50R20 MT Tires
20x10 -21 offset and 4.6 backspacing wheel

How far wil this stick out and will there be any rubbing

 

THose wheels are gonna stick out about 3.5 inches farther than the OEM wheels. You will have some minor rubbing and will probably have to do a little trimming to cure it. THey will work, but just be aware of what you are getting into. I think a 9 inch wide wheel, or a 20x10 with more backspacing would be a better choice personally.

 

so if i measure from where the oem tire is right now, it will be 3.5 inches farther out cuz i measured it like that and that would stick out alot.

 

Yeah, that is a lot. The outer edge of the rim itself will stick 3.5 inches farther out. The new tires you mentioned will stick out slightly farther than that since they will also be wider than your OEM wheels.

 

Will a 20x8.5 with 5.1" Backspacing (+10 Offset) fit with Toyo m/t 33x12.50 ok with leveling kit on that same truck?

 

Do it do it do it!!!!! I just went with the same set up except 18s. Barely rubbed, minor trimming took care of it. Mine are 18x10 4.52 bs with 33x12.50 toyo mts. Love the look too. All the lift I have is 2.5 AS

 

Yes Chanco79, that combo will fit better. You shouldn't have any problems with it.

 

Can I go any wider?

 

Yeah, you can go a little wider with the tire and wheel.

 

How wide before I rub?

 

It will depend on the backspacing of the wheel. If you go with a 10 inch wide wheel with 4.5 inches of backspacing and a 12.50 inch wide tire, you will have to trim. I'd try to stay with a 9 inch wide wheel with between 5 and 6 inches of backspacing (depending on the stance you want) and a tire that is 305mm (12.50 inch) or 325mm (13.00 inch) wide.

 

One more question and I am done. Since KMC Rockstars only come in 20x8.5 thats what I am stuck with. Now how does the backspacing work. Is 5 stick out more that 6 or vice veras? I appreciate all your help Wandell!

 

5 will stick out more than 6
