It starts shaking at around 38 then shakes like above said statements at 45. Once I get up to 60-65 it runs fairly smooth.

I took it to Discount Tire and asked for them to balance the tires and the guy said it won't help and as mudders wear they will shake. I politely called him a douche bag and went on my day.

I have had the PML on for over a year and also the tires. It does pull to the left but that happened after a camping trip. The shaking is getting progressively worse though. What do I need to look for on my steering that could be causing the problems. Everything seems good and tight. The shake is felt on the steering wheel, and it SHAKES.
