I am trying to figure out what is the biggest tire size I can put on my f150. It is an 06 f150 supercrew lariat 2wd with 2.5in leveling kit in the front and 2in in the back with 2.5in wheel spacers. I am looking to get after market 18in rims with tires. Thanks for reading.

 

Need to know wheel width and backspacing/offset.

 

I want 12.50 wide. And idk the backspacing offset ect.

 

If you are talking stock wheels, 12.50 is too wide for them. Maybe if you have 20s or 22s, but not the 17 or 18 wheels.

Just checked, even too wide for the 20s.

 

Wheel width, not tire width. Pick out the wheels you want to get, then decide if you want to still keep those spacers, and then we can determine the best tire size.

 

The rims I want are 18x9. The offset is 0 and the back space is 5.0" with a hub bore of 87.1mm.
