Can you do 305/55/20s on stock All Terrain??

Hey guys, just bought a 2017 GMC Sierra All Terrain. I requested that a levelling kit be installed by the dealership so I could install 305s (as all the research I did said they would fit the stock rim).

After picking up the truck I noticed it looked higher however it is still 2.5" difference between the front and back fender heights. I took the truck to Fountain Tire to install the 305s. As it turns out they could not install the tires as they were too big and rubbed. I ended up going with 275/60/20s instead (still look good but doesn't give it that aggressive wide look).

Turns out the dealership installed a 3" block in the back and a 2.5" level kit in the front. Now the tires REALLY look tiny as I have a small lift kit installed (which I didn't want...just the level).

My question for you guys, has anyone installed Goodyear Duratrak 305/55/20s on a stock All Terrain? All I want is a levelled truck with aggressive, wider stance. I may have to go with a new set of wheels at a different offset to get that wider look (as I don't want to install spacers).

So you had them physically try to put 305's on and they physically didn't work and rubbed. So why start a new thread asking if they didn't already work? You already saw they didn't and there are tons of threads discussing it...

 

I take it you aren't using your truck for truck stuff? Why do you want it level, it will sag horribly when doing any truck duties.

I don't get the question. If you have a leveling kit it isn't stock, are you meaning the stock rims or what?
