I have 325/60/20 tires on stock suspension & wheels. There is a slight rub at full lock.

I have the General Grabber ATX 325/60/20. They rub slightly at full lock.

I put on blacked out Fender Badges on my 2021 GMC Black Diamond Edition

I was able to fit 325/60/20 on stock wheels.

I upgraded tires to General Grabber ATXs. Very pleased with tire size & fitment.

Yes you can peel of the old one. The new one had an adhesive back and just stick on. I just but mine on top of the old ones & it looks professional to me.

On Facebook user Ofx2gv sells them. The console vault wasn’t ordered with my truck. But all the equipment it was supposed to have was there. Tailgate Audio, Aux Camera, trailer tpms & rear seat storage. Power steps also.

Any video from this test? It would be nice to see.

Has anyone been able to remove a center console for a jump seat and relocate the buttons to keep the rear heated seats? or remove the wireless charging from the console and have it installed into the top of the jump seat?

2021 Denali HD Black Diamond Edition

Thanks! Since my tires have the 3PMS I am hoping have a better experience when driving in snow.

I took delivery of my 2021 Sierra 3500HD Denali Black Diamond Edition yesterday. It came with the 275/65/20 Goodyear Wrangler Trail Runner ATs. I was surprised to see that they have the 3 Peak Mountain Snowflake.

I saw a YouTube video where someone put on 37”x13.5” Tires on stock Denali Wheels with no lift of level. No adjustment on the torsion bars. The person in the video said the only rubbing was against the wheel liners. This setup has me thinking About a 37”x12.5” tire on a stock 20” wheel with no suspension adjustment. I like the way the bigger tires fill up the wheel well. can anyone tell me if this is plausible? here is the video: skip to 5:42 mark
