Pturn

NITTO Ridge Grappler. Significantly better than the stock garbage which did nothing but spin on wet pavement let alone snow. I am usually a BFG KO2 fan but they didn't have the size I wanted and so far I like these better than the KO2s. I would recommend them.

There's probably an inch or so from rubbing fronts (didn't measure) but the running boards in the 3rd position just touch the side lugs in the rear so you might have an issue there.

I'm not sure but 285/50/22 fit perfect without level.

I might go that route or see if I can find just the amp. Did you have the spare connector near the sub not hooked up to anything?

Yes sir. Do I need to do something to bypass it? I didn't see anything in the instructions. I also had a spare connector near the subwoofer that didn't connect to anything which I thought was odd.

I am really starting to believe the Kicker powered subwoofer is not meant for the Denali trim. I installed the factory Kicker in my last 2015 SLT Sierra with Bose and it made a huge difference. I installed 19417164 in my 2019 Denali, tried different switch settings and added the bass control knob and can barley tell a difference. I also have noticed everyone posting that they are not impressed have the highest trim model as well. Am I on to something here? Anyone local to Ann Arbor, MI area and interested in my kit that has a non-Denali?
