Please help! 2017 Sierra 6.2 8 speed. Constant Steering wheel vibration. What should I do? (info in comments)

I knew buying this truck that the Chevy shake is a possibility but I took the chance. Fortunately the truck doesn't have any vibration except for in the steering wheel. And it's constant. From 5 mph to 90mph. It doesn't get worse or better it's always the same. So I got the tires rebalanced at 2000 miles this past weekend. Still did not solve the issue. So the answer is take it back to the dealer which I'm going to do. However a few things. I have 295/55/20 Toyo rt tires. A level and bilstien shocks that replaced the factory setup. I have ran 33 all terrain tires for years prior to this truck with no such problem but I went to an aggressive mud type tire. So my question, are the more aggressive mud tires the issue?
