20" Wheels..... what offset do I need? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

What offset do I need to go with 20" wheels on a 1969 Chevy C10? I'll be running 20's in the front and rear and need the offset. I just finished installing the Air Ride Suspension on the front and rear.

Thanks!

First off welcome to the site!

In order to determine the correct offset is usually up to the owner or tire shop, and the type of wheel/tire combination in question. It depends on the wheels, the type of suspension (different rear axle, discs front/rear, and many other factors. You might find more information on the Suspension portion of the site, but you will get plenty of feedback here as well.

Also, try a search for backspacing on 20" wheels and you will find many other posts on this same topic. Good luck on the search, I'm having the same problem...

By the way...

Also cflvulcan, love how the truck turned out! Love that color!

Thanks for the help! I have air ride suspension, stock rear end, and disc brakes all around.

How do I post a pic?

I think it's +13mm or +18mm.

What width wheel are you going with? 8.5, 9.5, or 10.
