Stock 02 Supercrew 4x4 XLT, 16" rims. Will I have any problems with that size? Also, If I decide to get new wheels theres no problem swapping them over right?

 

The only way to fit them is to use the oem wheels. They are an extremely tighf fit and will rub the frame at full steering lock. They are also a little too wide for the oem wheels. I would stick with 33's unless you plan on adding a lift.

 

I'd have to say it'd be very tight to say the least. That's roughly a 35x12.5 inch tire. I'd predict you'd get rubbing in a few different ways.

 

too tight. even if you were to trim enough to make it fit, you'll still experience major rubbing if you do any off-roading. get a body lift, then go for it!
