I do not have the shake when I have my stock 18 wheels and tires w/ the goodyears. But when I put my CK160 knockoffs on w/ hankooks on I get the shake at 70+mph. Here's the thing.... I do not get the shake when I have the stocks on the front and the CK160 on the back. Smooth as glass. Any thoughts?

I got call from the dealer. They are saying 3/4 tires are bad. One is a 3. The two are just above 20 and one is 40. Unfortunately I did not buy my tires at the dealership. So I called the place I bought them and they are saying that the road force balancing is not a definitive answer that a tire is defective. So now I have prove to them that something is bad with their tire.

I had a tech ride with me. He thinks it's the tires still. They are taking it to the Cadillac dealership on Thursday because they have a PECO meter and road force balancer. The saga continues

I still have the shake after replacing the driveshaft. I will be calling the dealer today to make an appointment

I got my truck back yesterday but traffic was too heavy to get it up to speed last night for any length of time. I got close to 70 and didn't feel anything. I'll get on some open roads today. I was very pleased with how my dealer is handling this so far.

I had my appointment today at my local dealer. They will be replacing my driveshaft. It will take a few days to get it in. Fingers crossed.

I put my 18s back on and there is still a slight vibration. Not as pronounced as when I had my 22s on it. I stopped in at the dealer and made an appointment for next Thursday. First question he asked if my wheels and tires were factory. I know I will be never win this battle. They have take off 22s sitting in the showroom I ask for him to take test drives with all three sets to make sure it vibrates with all of them. I might have burn a vacation day and babysit to make sure this gets done the way I ask.

I'm going to throw my name in this as well. 2015 GMC DC 6.2L All-Terrain. Had a slight vibration with the 18s. But not very noticeable. Put knock off CK160 with Hankook 305/45/22. 2 rebalances and 1 load force balance and no change. All three times they said they were not balanced. Vibration starts 65mph and vibration increases as the MPH goes up. Going to put 18s back on and take it to dealer. Not expecting an help from them.

Has anyone tried taking their 2015 to the dealer and have them do the update?

I wanted to keep the 18's for winter. Then buy a set of 20" or 22" wheels next spring. Have really decided on which ones just yet.

I had asked when I bought my truck from them and the want like $4k.

What kind of wheels are they?

I'm in Harrisburg. Wheels only? How much?
