looking at rims on tire rack and those are the specs of 20x10's. whats all that mean and how far will it stick out from stock rims??

 

They will stick out about 2.5" more then a stock wheel. Stock wheel is only 7.5" wide with 5.5" backspace.

What set-up you have or are you going with: what size tires, leveling kit, etc? To wide of a wheel may create rubbing issues.

 

His info says he has a 2000 f-150. His oem wheels are either 16x7 with 4.5 inches of bs or 17x7.5 with 4.5 inches of bs. That wheel will stick out 2 inches farther than oem 16's and 1.5 inches farther than oem 17's.
BS is the distance from where the wheel bolts to the hub to it's rear edge. Offset is the distance from where the wheel bolts to the hub to the center of the wheel.

 

so what will stick out more with 18's. backspacing of 5.43" or 6.39"?? i had 17's on there stock and have 02 fx4 rims now so.

 

Whoops! sorry about that, i always forget to look up in the corner for viechle info... on top of that i guess because i have an 08 i always assume 04-08.

 

The 5.43" bs will stick out more.

325/65/18 Nitto's are a 35"x13" tire (34.88"x12.99")
