20" WHEEL FITTMENT

[TEAM THC]

Id Like To Put 20"s On My '82 C10 1/2ton 2wd 5lug
Id Like Some Info On Backing Spacing, What Are The Measurements
For My 5lug Pattern. Are Threr Any Problems With Fit(rubbing).
And Any Other Info I Need On Sizing 20s For My Truck.

these are 5" backspace, of course there's no bed on it and i haven't slammed it yet. these trucks have huge wheel wells. you shouldn't run into too much problem at all. your measurements on lug pattern are 5 on 5"

hey chevye, did you have any problems getting your front centercaps to work? i remeber having that truck with that wheels and had to take the dust cover off the front to get the centercap to work.

[CHEVYE]

they fit right up. i have the smaller non heavy duty brakes on this truck though. i'll have to try em on my other truck since it has the heavy duties. i wonder if there's a difference in the rotor cap size of the bigger brakes, does anyone know?

[milehightoyz]

cool...looks like a nice project...im thinking of picking up another set for my burb. they are pretty niec wheels for the money. thanks.

those look like the "boss"...somethings 301's or 304's maybe....that are on www.bigjimsrims.com for around $145 apiece

[CHEVYE]

yeah, you can get a good used set with good tires for about $800. i'm thinking of getting 22's and 18's so i can run a 20/18 combo on the DD and a 22/20 combo when i get this other truck done.

the center caps on the rotors are too big to fit over some of the center caps. on my 77 i had to get the center caps machined, and the rotors machined a lil bit.

I Have 20s Boss 305s, I think. Didnt have any problems with the center cap.

How wide of a wheel are you planning on going with on the front and the rear? And, how much of a drop do you have or plan to have?

5" bs on a 20x8 should work in the front. Out back, 5" bs on a 20x10 should work. If you go 20x8's with a 5" bs on all four corners, the rears will be offset in more than what is needed, but it should work. And as Chevye said, your bolt pattern is 5 on 5. If you haven't radically altered your suspension or brakes, you shouldn't have any rubbing issues with the correct offset.

these are 20x8s with 4.5"BS and 245/40s, and 20x9.5s with 5.5"BS and 275/35s. the fit great.
