They're are some good reviews on both the AT and the MT.

I have the Mickey Thompson MTZ. Best tire I have ever owned. My current set has about 37k miles on the tires and they still look like almost new and have about 14-15/32 of tread left

I hate the druatrac tires. Anyone running the 285/60/20 ko2s on the AT4 all stock? I think I'm going to get the OE 20s.

Very rare rub noted on passenger side fender inside of lower molded flap on sharp right turn only when going up a slight curb or bump. Otherwise no issues

Did you happen to have these tires mounted before you put on the RC leveling kit? I have a bone stock AT4 without a leveling kit, so I'm wondering if 285/65/20 will work. TIA.

Did GM Accessories lift at delivery to make it the equivalent of an AT4 then did the front leveling and ran the stock 275/60/20 for a little while before going to the 285/65/20. I know lots of people running the 285/65/20 on TrailBoss and AT4s on factory rims with no problems actually think they may get a little less rub

Does anyone know if the 295/55R20 Nitto Ridge Grapplers will fit without any modifications on a stock AT4 with stock wheels.

Has anyone done this yet? Pics would be awesome.

Didn’t read all 5 pages, and this might all sound pretty cute compared to the 35+ many and running in here but...

Has anyone else noticed that the off road performance package duratracs are actually smaller than the stock AT4 tires?

33’s stock and 32’s on the off road pack... frustrating.

35x11.50r18 Toyo Open Country AT II

Rough Country 1.5" level kit was necessary but no rubbing whatsoever.

With the right wheel spacer you can go as big as you want! Ha ha ha

PS I don't recommend this!

Now thats what you call a long arm kit....

I’ll save you some trouble. I put this size on my Sierra with a 2” level and could hardly turn without major running. I ended up heavily modding the fender wells and made them fit but it was a pain. I’d go 286/60/20 on a stock AT4
