Moderator Txab was able to fix the poll, if anyone cares: Unfortunately the 3 results that were collected were lost.

I can't vote either. Wants me to vote in all size categories. My truck only has 4 tires and they are all 18s. Lol this truck just feels different than my 2008. It feels stiffer but lighter. I can also feel every crack in the road with my hands on the steering wheel. When I know I am on a glass smooth perfect road, sometimes it has a vibration and sometimes not. Could be at any speed. I'm really starting to think about harmonics and the new stiffer lighter frame.

Just swapped out 20" Conti's for Michelin LTX M/S2 and am very happy. The Conti's were OK until they got some heat in them or you aired them up past 34 lbs, then there were horrible on the highway. Not so much vibration as shuttering over every imperfection, very harsh.

 

I first tried Nitto 421Q's (SUV tires, looking for better ride), that was a huge mistake. Aside from 2 of them having radial runout they were way too harsh. Swaped into the Michelin's and now it's close to perfect.

 

One big difference I notice is around town. The Conti's were very soft around town, gave the truck a floaty ride which is what I supose GM was going for. The Michelin's pick up a bit more road imperfections but give me a more connected feel. What's impressive is they soak up the bigger bumps but I feel the little things, it's counter intuitive. On the highway they are golden, no vibration past 90mph and track straight and true.

 

The Michelin's are the most expensive @ ~$225 / tire but they are worth every penny.

You should also add an option for people who are not having vibration issues. Otherwise this thread is gonna look real bad...real fast

they put Hancooks on mine today and I still vibrate going to find a tire shop to road force they said they matched balanced mine but I still have vibration

[TxTruckMan]

My vibration is in the floorboard and is rpm based, mostly during low RPMs while accelerating. So not tire related.
