You shouldn't have to run spacers up front because the lift kit is already pushing the wheels out. I've seen some people say it pushed it out between 1 to 2 inches so you shouldn't rub on the UCA. I'm guessing with a 12.5 wide and being a gmc with the squared wheel wells, you will probably have to trim the plastic and remove the metal bracket behind the front wheel wells that hold the mud mudflap on. I cant see you having to cut the bumper though. So you may want to install those and see how much it pushes the wheels out then order spacers for the rear to match the front track. My guess is you'll need 1.5" spacers for the back Sent from my SM-N975U using Tapatalk

Also the BDS and zone 4" kits will push the front wheels out with the new spindles anywhere from 1 to 2"s on each side depending on who you ask. Sent from my SM-N975U using Tapatalk

A 0 offset will be too much without trimming. I believe I have seen people here run 1/4 inch spacers roughly 7mm and able to clear 12.50s. Its not much and won't have your tires flush with the body but will prevent you from having to trim too much. I've seen guys run stock lugs with the 1/4 spacer but you lose a few threads. I personally would order new studs 1/4 inch longer Sent from my SM-N975U using Tapatalk

I had the dueler AT on my 17 denali and loved them. I have the Alenza HL on my 19 denali and these are way worse. Sent from my SM-N975U using Tapatalk

Did you have any rubbing? Sent from my SM-N975U using Tapatalk

Figure stock offset on 9" wheels is 24 or so so you would be pushing the wheels out about an inch. I've seen people fit 35x12.5s on stock wheels with a 3.5" lift. But going 11.50 wide wheels instead of 12.5 might give you just enough clearance On my denali, I have the stock 22s and will be doing 285 55 22s with a bds 4" and will clear no problem Sent from my SM-N975U using Tapatalk

I live an hour from niagara falls Ontario. If the boarders were open I would get 1 for you. Sent from my SM-N975U using Tapatalk

Here's one with the GM 2 inch lift and then a level in the front Sent from my SM-N975U using Tapatalk

Another member put on the gm lift and was able to clear 285/55 r 22 ridge grapplers and had no rub and no trim. Here's a Denali with just a level, and a Chevy with the GM 2" lift. I think the Denali rubs slightly because of the squared off fenders where the Chevy is more round Sent from my SM-N975U using Tapatalk

Depending on where you live I have the stock 275 50 22 alenza tires for sale. I think they go for 250 each so I'd let all 4 go for 600. They have a little over 4000 miles on them Sent from my SM-N975U using Tapatalk

I would go with some 285 50 22s That's a little over 33" the 305 45 is 32.8" so you get a little more sidewall with the 285s and they fit without rub in stock suspension Sent from my SM-N975U using Tapatalk

That's what I'm looking to run as well. Just wa.ted to see how they looked Sent from my SM-N975U using Tapatalk

Do you have any pictures? Sent from my SM-N975U using Tapatalk

No one else have this size set up? Sent from my SM-N975U using Tapatalk

Looking to upgrade my tires to something better than the alenzas that come stock and after hours and hours of research I have learned that a 12.5 wide tire will most likly rub the UCA. So I'm now stuck between 3 tire sizes: 305/45r22 - these are a P tire and actually come in just slightly shorter than the stock tires, and I'm really looking for something that will fill out the wheel well better 285/55r22 - these are E rated and are 34.5inches tall which I have read from a few people that with a lift which I plan on doing they dont rub. 285/50r22 - these are just over 33 inches tall and are still an E rated tire and I've seen people run this set up without a lift or level with no rubbing This will all be on the OEM 22" wheels and I'm looking for people who have gone to an E rated tire to see how much more harsh the ride really is.
