Im getting a 7.5 fabtech lift on my screw. Will the tire size 315-70-17 bfg all-terrain be big enough for this lift?

 

Yes, that is basically a 35x12.50 tire. Most people with 6 to 7.5 inch lifts on 4x2's seem to run 35's.

 

Alright another question! i am wanting to go with the Helo Max 6 rim http://www.4wheelparts.com/PDT71847.aspx

I will be getting 17 inch rims with 315 70 17 inch tires. now what backspacing should i get? I want the tires to stick out a little bit with the 7.5 but not too much. thanks!

 

The Fabtech lift will increase your front track width, so just about any wheel is gonna stick out. I'm not sure how much your front track width will be increased.

 

Fabtec recommends 315/70/17 size tires(approx. 34.4" diameter) on their 6" perfomance 2wd lifts. You should have no problem with a 35/12.50 with a 7.5" lift.

 

Yall dont think that the 315-70-17 will be too skinny with this lifT?

 

No, you are talking about a 315mm wide (12.50 inches) tire.

 

That tire will fit fine....you will have pleanty of room, I hve 6" on a 2WD and run 315's easily.

As far as the wheels sticking out, I would not get a big offset wheel, cause the fronts are going to be about an 1"-1.5" wider on each side anyhow. You might want wheel spacers for the rear if you want them to look the same.
