what size tires can i run with out rubbing ive got a 1998 f150
with a 3.5" spindles and 1.5" daystar for total 5" lift front and 3" rear i want to run 305/70/16 terra grapplers

 

If thats a 33/12.50 or 33/11.50 you'll be fine. Just check their specs sheet on the website to see what they actually measure out too. You could probably even do a 35/11.50 with minor rubbing over bumps and at full lock.
