Sierra 1500 AT4 tire & lift help

[Michael1424]

Hello,

 

I recently bought a 2019 GMC Sierra AT4 and I was wondering what the biggest tire size I could fit without rubbing would be? I was also wondering what kind of leveling kit I should get for this truck since I heard the AT4s already come lifted out of the factory. I have 18" rims and I would like to get the Nitto Ridge Grapplers unless someone else has better all-terrain tires for mostly road use with a little off-road use.

Hope to hear from anyone with suggestions on this topic, thanks!

I am a big fan of the BFGoodrich KO2. I usually buy load E but bought my RST cam with 20” wheels so I bought load D and like them very much. The Nitto is a good tire also. You can go to the Discount Tire website and compare the specs, weight, price, etc.

I just had the 1.5” MotoFab installed on my 2020 AT4 with 295/60R20 Ridge Grapplers today. It looks great, no rubbing at all. I haven’t been able to look close but I don’t know that you could go any wider without risking rubbing the a arm.

That sounds sweet! You got any pics?

I don’t have by pics yet. I’ve been at work from daylight until after dark so I haven’t been able to get any. Hopefully this weekend I can get some pics of it.
