Tire clearance help

xps800doo · January 31, 2018

I would like to throw a set of these on the new truck, i know gm offers a 20" but i believe its a 8" or 8.5" will there be enough clearance to run them with out a level kit or rubbing? i plan to run a BFG AT 265/65/20 tires so not going crazy oversize or anything. what do you guys think?

I drive on factory 20’s with 275/65. No rubbing. These will have better clearance if the offset is 0 to 15.

I CALLED TIRERACK AND THEY SAID 0 OFFSET. SO SHOULD BE OK?

I believe so. You should be sitting super flush with the fender and the turning at full lock should be OK 265/65-20.

that is great news! level kit is not out of the question, just haven't decided if i want to or not yet!

I enjoy the ride of mine on a level. Really no difference I can feel. My 5’2” wife finds it more difficult to get in. But it’s a great show none the less.

I would go with it. I plan on getting wheels and fender flares this spring. 0 offset is what I’m looking at too.

To your knowledge is there any adjustment in the factory torsion keys to get it more level? Haven’t looked yet, but that thought crossed my mind.

Yes you can turn the the keys to get a more clearance. I’m not sure if it’s quite 2” or not. People say it doesn’t diminish the ride quality. I bought new keys and had them installed.

ya there is lots on this forum about cranking up the keys or level kits or lifts. Lots of people just say to crank the keys and that will give you the 2" like a level. I went with 2.25" keys and then a 2" block in the back, I then had the keys cranked up a little from there so there is only about a 1-1.5" rake. That way when the sleds are on the deck my nose isn't pointed in the air.

Bhurt, what wheel/offset/ tire setup do you have?

these are factory 18's, with stock 265/75/18 duratracs if I remember correctly. I will be going to a 35" tall tire next.

I’m thinking the same thing. 305/55 or whatever the conversion is. Not sure how much clearance I’ll have on a level.

Make sure you adjust ypu headlights cause now they are aiming upwards being the trucks are adjusted for a 2" rise up in ass.
