305/55/20 Duratraks on stock 20" rims?

[cflrules]

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).

 

My question for you guys...does a 2.5" level kit not give the same height front and back? From the pictures does it even look like it's been installed. The 2nd pic is the front wheel well, 3rd pic is the back.

 

Also, has anyone tried the 305s on stock rims?

 

I may have to go with a new set up wheels at a different offset to get that wider look (as I don't want to install spacers).

 

Thanks in advance for any advice!

you should be able to see better if they installed a bottom strut spacer in the front. but that doesn't look like it's leveled to me.
