Will 275 60R20 fit on 2017 sierra w only a level?

[Closm38]

Hello first time here.   I have a 2017 GMC sierra that I will be installing a Rancho Quicklift on.  I don't want to do any trimming.  I currently have the stock 275 55R20.  I will be keeping the same wheels, i just would like to know if I can go to the 275 60R20 without having any issues?

I'm running 295/60/20s with the front 1 inch higher than stock. Sorry I'm not more help with that exact size but I would bet they'll fit fine

I’m running 275/60/20 with no lift or level at all. Zero issues.

Did you have to do any trimming to be able to fit that size tire?

None at all. Just cranked the front end up 1". My truck is a dually, but you should be fine as long as you keep the stock wheels, or at least don't run a ton of offset on aftermarket wheels.

What brand tire are you running.   I'm looking into getting the toyo open country AT3

I agree that you may have no issue with this slightly larger tire size even with a stock suspension.   Until recently I would bump my tires up a size at tire change time.  There is some inner thinking/feeling that  this makes our trucks tougher and more capable.  The reality is that the stock tire size gives you optimal efficiency.  The  Toyo open country AT3 also higher load rating in your stock size.  Tires, for most of us, are a major expense and I choose quality over quantity.  I do appreciate the value of a truck's appearance.  Larger tires and a moderate lift are my preferred look.  However, until I can afford to get the look along with improved  off-road capabilities, stock is my choice.

My wheels came with Goodyear Wrangler AT’s. Waiting to see how they perform this winter. I’d prob eventually go with KO2’s once they wear out.

 

I do still have my stock wheels with Blizzaks, if the snow gets really bad. I leave for work at 4am each day and roads are never really plowed.

No trimming.
