2914 GMC Sierra 1500 vibration in steering wheel

[Brock Allen]

I have a 2014 GMC Sierra 1500 and the ride is terrible. I bought this truck almost 2 years ago and the past few months the ride of the truck has been terrible, Every bump feels almost as like there is nothing absorbing the impact of the road. I have replaced the struts and shocks with the bilistein 5100's and i have aftermarket 20 in fuel wheels with the nitto ridge grapplers (LT285/55/r20) I'm wondering if this is caused by the tires or what???? i also have a vibration in my steering wheel. Any suggestions would be greatly appreciated. If I can't get it figured out i'm probably going to trade it in for something different. Thanks.

Probably the tires and rim size.
I have 35x12.5x18s and, after the 5100 install. it rides great!
Prior, with the stock shocks, I'd bounce way more than I liked.
I, also, notice a difference on tire pressure - at 45 PSI, it's harsher so I keep the BFG K2s around 39 PSI.

I have 275 55 r20 I hated it from the test ride but can’t judge it on the street princess rim. I feel every pothole every bump. On the freeway it’s horrific. Feel like a Jeep Wrangler lol. Jk Jeep fans.
I go offroading now and than. Need that extra tire for you may never know. 
it helps for pot holes etc.

Id hate for the wife to curb the 20s. I’m just saying.

im awaiting to put on my 305 70 r17

larger tire. We’ll see.

Does the vibration in your steering wheel occur all the time or only when you apply your brakes?
