What is the largest diameter/width tire I can install? 2015 GMC All Te

[HotRod20]

Guys,

 

I am new here; Forgive me if this subject has been hammered down before in the forum. I want to install the widest tire I can using the stock 20 inch wheels on 2015 GMC All Terrain with Z71 package. I do not have an aftermarket level or lift kit and need your opinions. Looking at the BFG AT KO2 tires.

 

Thanks

275/60r20 is largest w/o lift/level.

That is what I determined from researching..I ordered the 275/60/20 KO2. I don't want to level because I pull a race trailer pretty often and the truck is level with the load.

 

Thanks for the reply
