i just installed a PA 3" body lift on my 01 f150 supercab and i am ordering a 6" fabtech lift whats the best tire size to run and back spacing for rim i am thinking about 37 or 38 x 12.50 or 13.50 x 16 but if ne one has a tire size that works better let me know thanks

 

thats a nice setup your gonna be running bro! check out cashel`s truck he`s running 38/14.5/R16 Toyos on his truck and it looks Awsome I think you can run a 38/15.5 but I`m not sure what backspacing you would need for that tire

 

I've seen several people fit 38x15.50's using a 10 inch wide wheel with 4.5 inches of backspacing. Personally, I'd go a little smaller because it's a really tight fit. Maybe a narrower 38 or a wide 37.

 

I say go with a 38, because eventually ur gonna want to go bigger, i have the same setup with except i got coilovers so it about 2" higher with 37's, they looked good when i first got them but now i wish i would of went with a 38

 

the absolute biggest you can go is a 38x15.50. i wouldn't recommend such a wide tire, though. you will experience rubbing on the tie rods and torsion bars. i would stick w/ a 38x14.50 at the widest. you will need a 10'' wide wheel with 4.5'' of backspacing to pull this off.

 

Check my gallery, I'm running 38x14.5x16 on a 16x10 wheel w/ 4.5" backspacing and I rub on my tie rods at full lock. I love the wide tire stance, but I wouldn't go any wider than 14.5".
