I'm looking for tires, I have an 06 xlt 4x4 5.4- I like the stock wheels, My question is, what is the largest tire I should put on my truck, its stock,no lift
semi aggressive, mud, all terrain etc.

Thanks

 

I'd stick with a 285/70-17 or 285/65-18 (33x11.50's) or 33x12.50's.

 

if you're already going to spend that kind of money for new tires, might as well make it look nice. get yourself a 2.5 or 3 inch spacer ($100 - $300 depending on application) and go with an aggressive tire, such as MT or AT. it makes it a complete different truck when you do that. also consider what this truck's main purpose is before taking action though. is it your daily driver or your off road toy?

here's my daily driver, although i have different wheels, stock wheels look very nice too.
