Looking at pulling the trigger on a new set of wheels/tires and I am very confused on what size I can fit and how much the wheels will stick out from the fender. I've searched but am still very confused on what will work with my truck.

I have a 2010 Lariat, 4x4, super crew, with the factory 18" wheels. No leveling kit yet, but am going to put a 1.5" kit on soon.

For the wheels, I like the ProComp 8101.

The size is 20x9, backspace is 4.5 in, and offset is -12mm.

How will this fit in the fender? Will it stick out a lot? (I'm having trouble doing the math in my head today...)

Another option is the RBP 94R.

The size is 20x9, and it is available in +10, 0, -12, -25 offsets. What would work for keeping the wheel/tire about flush to 1" out of the fender?

Also, with a 1.5" spacer up front, what size tire can I run? I don't want to go any bigger than 32" or 33".

Thanks!

Adam

 

You can fit 33's with a leveling kit easily. A 9 inch wide wheel with 4.5 inches of backspacing will stick out 2.5 inches farther than your stock wheels. Personally, I'd prefer a 9 inch wide wheel with 5 inches of BS which would stick out 2 inches farther then the OEM wheels.

 

Wandell - thanks! Looks like I need to find something other than the ProComp. It only comes in a 4.5" backspace and that is too much for me.
