I have an 05 4x4 , and IM going to be doing a leveling kit. not sure if Im doing a 2.5 or a 3 yet. But I wanted to have an idea as to what is the biggest wheel/tire setup without any rubbing or complications ??

 

Probably a 35x12.50 is the biggest you can go with a 3" and 2.5" leveling kit. Some people have minor rub on the upper control arm at full lock. It that doesn't bother you, 35's will look sweet.

 

any pics of what it would look like ?

 

Here is a pic a 35's on an F150. Im running 33's on my truck right now though

 

You need to have stock wheels or at least close to stock backspacing... I'm pretty sure that's what I remember reading about it

Most people will stay away from the 3" leveling kit due to the stress that it puts on your front end... I would stick with 2" or 2.5"

 

What about with no level kit?

 

Umm, not real sure... I'm sure some of the other guys can help ya out with that question

without level if its a 4x4 you can fit 33s if level 35s

 

Thanks!

 

This is from another forum Hope it is OK. god info.

This is for 2004-2008.

On a stock truck without leveling kit you can run 33X12.5" tires if it is a 4WD and 31X12.5" tires if it is a 2WD, using stock wheels.

On a leveled truck(2" kit and larger) you can run 35X12.5" tires on a 4WD and 33X12.5" tires on a 2WD truck, using the stock wheels.

Using aftermarket wheels you can run 35s on a 4WD if the wheels follow these guidelines:
-For an 8" wide wheel the backspacing is 5.5 inches.
-For and 8.5" wide wheel the backspacing needed is 5-6 inches.
-For an 9" wide wheel the backspacing is 4.5-5.5 inches.

If the wheel specs are not listed about you will more than likely have to run 33s or even smaller to avoid too much rubber and trimming. These specs are the basics for tires fitting well but you could run 35s if the specs are very similar but you will face bad rubbing.

For a 2WD truck and after market wheels you can run 33s with wheels that fit withen these specs.
-For an 8" wide wheel the backspacing is 5.5 inches.
-For and 8.5" wide wheel the backspacing needed is 5-6 inches
-For an 9" wide wheel the backspacing is 4.5-5.5 inches.

If the wheel specs are not listed about you will more than likely have to run 31s or even smaller to avoid too much rubber and trimming. These specs are the basics for tires fitting well but you could run 33s if the specs are very similar but you will face bad rubbing.

Remember that these are the basics to running aftermarket wheels and tires, certain tires might not rub but others might because of aggresive sidewalls.

These specs should work for most people and instances but if you are worried about fitment get the tire shop to mount the tire on the wheel and put it on the truck then turn the wheel to full lock in both directions to see and possible problems. If the tires you plan on running aren't 12.5 inches wide you still might be able to run 35s because of that reason, for a 4WD and some aftermarket wheels or 33s for a 2WD. It's best if you can find wheels that are a happy medium between the two backspaces for the 8.5" and 9" wheels because you will face more rubbing if you go for 6" of backspacing on a 8.5" wheel instead of 5.5 inches that's right in the middle.

For those who are curious. The stock wheels(17 and 18") are 7.5 inches wide with 5.5 inches of backspacing. The bolt pattern is 6X135mm.

Big thanks to PawPaw on this one.

If you have any instances where you find that these specs haven't worked for you please let me know and I'll make the appropriate changes, please PM so I will see it.

Hope this helps.

 

I have the Rancho Quick Lift, my wheels are 9x18 0 offset 5" back space, tiers are 325/60-18.
Had miner rubbing on the back edge of the wheel will Wehr the mud flaps are. removed the front mud flaps and used a hummer to great 1" of extra space and it is OK now. I have 0.5" of extra space now at full lock.
