Wheel sizes?

I have stock 04 prerunner double cab 6 lug rims and I am ordering rockcrawlers. Can anyone help me with the sizing? What's all these measurements i need? Backspacing?

 

You'll need 6 on 5.5 lug pattern. As for backspacing, what size tires do you want to run? Stock BS for 1st gens is 4.5.

 

265/75/16 a/t's

 

4.5 bs will be perfect then.

 

alright thanks. what does the diameter and the width mean?

 

Of the wheel?

Diameter would be how tall it is. You would want 16" to fit those tires.

For the 265's I would go with 8" wide rims.

 

diameter is the height of the rim, width is how wide it is. stock measurements for you are 16 inches in diameter and 7 inches wide. you can play around with these two if you want a wider/taller rim. but if you want to run 265/75/16 tires you will need a 16" rim
