would 285/70/17 nitto terra grapplers fit on this.

 

Id Id like to have that rim as well, but i want it in 5.14" back spacing.

 

6x135mm is the lug pattern for 04-08 truck's which is the wheel on top. It also has a 4 1/2" backspace and is 9 inches wide. A 305x65x17 may be a better choice. They will also stick out 2 1/2 inches more than stock. A leveled 4x4 should clear these with no rubbing.

 

i have a 4x2 will it still be alright?

 

I'd go with wheel with a little more backspacing, like 5 to 6 inches.

 

what determines backspacing the wheel or the tire?

 

285/70/17 will have some slight rub when you have the wheel full cranked to one side, especially if you are on an incline. I run 285/60/18 terra grapplers and that's what I experience. Not a big deal and definitely worth having some fat tires.

 

Backspacing is simply a measurement. It's the distance from the mounting surface of the wheel (where it bolts to the hub) to it' rear edge. The more backspacing, the more the wheel tucks in. Less backspacing means the wheel will stick out more. Your OEM wheels are 7.5 inches wide with 5.5 inches of backspacing.
