3.5 inch lift. Tire sizes??

[Tyler Shelley]

I have a 20 Sierra Elevation with a 3.5" Rough Country Lift. I swapped my factory wheels with a co-worker for some 20x10 with a -24 offset. He has some "what looks small" 285/55 R 20 tires on it know. What tire size do you recommend. My main question is what is the largest tire size I can run

Depends on do u want taller or wider..?  On chevys they go to 295/60/20 =34x11 or 305/55/20 =33.5-12.50 both these sizes are popular on here. Some fit 35s but trim.  So on yours they use a little smaller with the wheel well shape. I'd measure it and see is a 295 60 would fit. That gives u a little width plus the heigth.

I have 295 60s with a 3 inch on stock 20s, no rub.

I was looking into 295/60R 20 but i dont have factory wheels. My wheels have a -24mm offset. I think I will buy a set of that size and try them. They are barely wider than what I have but taller than what I have now. The hight is what I'm  after. The width is what is worried about.

Take a look at the custom offsets gallery,  lots of wheel n tire combos on there.

I looked at them. They have a lot for the previous gen trucks but they dont have a lot for this gen. If they do, I can't find it. I traded my factory wheels for these with my co-worker. I can trade back with no problem, but I really like the way the wheels look, but the tires look to small

There is a few GMC 1500s, not sure on your package tho.. Most with a 20x10 with a 3-3.5 lift have 33-12.50-20 or 305 55 20.  The 6 plus inche Lift most are 35-12.50.  

 

Turn the wheels and measure how much room you have, that will give you a basic measurement on how  tall/wide you wanna go. An inch taller looks like it would help you a ton. Remember an inch taller is a 1/2 inch bigger all the way around...really isn't much.

I've got the same truck just different color. It's getting the 3.5 rc lift today..  what size tire did you end up going with? I've got 33/12.5 r20's to put on it but thinking I have to buy different rims. Kind of sad cause I hate to get rid of my ballistics rims..
