I have a 2008 F-150 Super Crew XLT. I'm looking at putting a 3" Leveling kit on and 18X10 rims.

What is the best tire size for this setup? I want All terrain tires.

 

Offset is -25
Hub bore is 87

 

First do not go with a 3" level, that is too much. Either go with a 2" or 2.5". Second is it 2 or 4wd?

 

it is 4WD

 

Those are going stick out quite a good bit, you are going to want to go with nothing more than a 33 x 12.50 or something like a 305/60/18. BFG KO's, Mickey Thompson ATZ's, Nitto Terra grapplers would be some good choices.

 

Any other suggestions ? I'm totally clueless about tire sizes

 

Read the sticky at the top of the page titled calculating tire size it will give you a better understanding.

 

I'd say 33's

 

I want the biggest so what size 33's. Might be buying an 18X9 instead. Offset is -12

 

When you consider stock offset is +44mm, you're moving an awful lot of tire outside the wheel well.
