Your OEM wheels are 17x7.5. When you are looking at aftermarket wheels in any form of advertisement they will be listed as 17x8, 17x9, 17x10, etc. As far as the Performance Accessories kit, I am on my third truck with a PA body lift and have never had a single problem.

the size that is on my truck now is 255/75-17, what size is that in inches? Also the rims on there right now are not stock, the auction we bought my truck from where arlready on there and i cant tell what width they are. Cause if they are 17x10 then i dont have to get new rims. When i buy tires how do i know if the tires will fit on the 10in. part? as long as they are 12.50 they will right?

 

Yeah, a 12.50 inch width or 305 mm width tire will fit on an 8 to 10 inch wide wheel. You can go to any tire manufacturer's website and look up what width wheel is approved for each size and model tire. As for a 255/75-17, that is an odd size. It would be approximately 32 inches tall and 10.00 inches wide (32x10.00-17) the best I can figure. Are you sure that is the right size? Most 4x4's came with a 265/70-17 which is basically a 32x10.50-17.
As far as telling the size of your wheel, it could be stamped on the back side of the wheel. If it is not, you will have to measure it. To measure it, remove the tire and measure form the inside edge of the bead on one side to the inside edge of the bead on the other.

 

so if i got 33x12.50-17 tires and put them on the rims that are on there now it will fit if they are 17x10 or 17x8?

 

Right, they will fit whether they are 8, 9 or 10 inches wide.

 

Whew- Wandell, you have the patience of Jobe. I think Speed D owes you an ice cold beverage!

 

 

ya i do owe him one, but i aint old enough to buy it, thanks for all the help wandell

 

Hey, that's what this place is for! I know what you are going through. It is impossible for every tire dealer to know exactly what size tire with what size wheel will fit on every truck. That's why it's nice to have places like this where owners of trucks identical to your's can share information. Just don't ask me what size tire you can fit an a Hummer H2!

 

hey wandell, with a 3" body lift from PA would 35x12.50x17's fit without any rub or cutting off any thing or should i stick with the 33x1250R17 (305/65r17) how do u convert from 33x12.50 to 305/65?

 

Yeah, you will have to trim the front bumper's lower plastic valance a little to fit 35's on wider aftermarket wheels with a 3 inch body lift, but they will fit. As far as the conversion of 305/65-17 to 33x12.50, I'm going by Pro Comps advertisments.
