I just got these put on friday night.They are 20x9 Liquid Metal Lithium 6 with 275/55/20 Michelin LTX M/S tires. After a test drive I'm disappointed that they shake pretty bad and they even suppose to had roadforce balancing. One of the back rims had some scuff marks or something in the chrome and discounttiresdirect told me to run it and they will order me another rim and tire to switch it out with. Well I did a burnout not thinking my truck would with them on and roughed the tread up on the tire that they will be getting back. It tore the edges off the treadblocks. I don't know what i should do now. I'm affraid they will get the tire back and charge my creditcard for the tire. Anyway I just wish they would have drove smooth and not shake. Anyway tell me what you think of the pics!

Did they remove the brake clips off the wheel studs?

 

[GrayZ]

I ordered them from discounttiresdirect but I put them on myself and they wasn't any clips on the studs!

 

[08RCSB]

What year truck?

 

[GrayZ]

Its a 2001 Z71 and it only has 30k miles on it!

 

[08RCSB]

Hmm, I am not sure if the NBS's have them or not.
You have rear disk brakes?

Someone else will chime in who knows if they have the clips. Is the shaking in the steering wheel or out back?

 

[slowtowpig]

yes it shoulda had the clips unless somebodys already had the rotors off the truck.

 

[08RCSB]

Go look for the clips first. Just a tiny metal clip on the wheel stud.


If you don't find anything, are the wheels hubcentric? If not did they provide rings?

 

[GrayZ]

The truck has disks in the rear and I have had the rotors replaced before because they rusted where my truck sets alot. The wheels came with hub rings! They are smooth at first then you start feeling it shake about 40mph and it is bad about 60-65 and it gets a lot smoother once up to about 85-90mph. The steering wheel shakes and you can feel it in the floorboad a lot when you sit in the passanger seat!

 

[slowtowpig]

get the tires turned 180* and rebalanced.

 

[08RCSB]

Lugs are torqued properly? 140 I believe?

 

[GrayZ]

I always put the lugs on hand tight with a gorilla wrench. Would it make a difference if they ain't torqed correctly?

 

[08RCSB]

Yes it could. Try re tightening them. Probably the easiest fix, too. First things first.

 

[GrayZ]

I just torqued the lugs at 140lbs and took it for a drive but the steering steal shakes alot at 50-55 and I can see the passenger seat shaking which I assume would still fell bad when sitting in the seat like I did last night and I could feel the floor board shaking bad! Now What?

 

[08RCSB]

Dismount the tires and have them rebalanced?

 

[BlackedOutHoe]

sounds like an alignment if it's shaking everything at highway speed

 

[maka]

sounds like the tires need to be rebalanced.. Swap the ones from the rear into the front and check... I had this problem with 3 sets of wheels... actually.... my 22s I have now are like this and I am going to have to get the 2 front ones rebalanced to fix it.

 

[red2000]

rebalancing doesnt fix it.

mine shake at 45 and 65 i took them back to kaufman the day i got them on and they re balanced them and then told me something about the way the wheels mounted they werent exactly centered. i even had the gmc dealership do an alignment and balnce them and it still shakes.


theres supposed to be some type of hub centering rings or something? im not really sure

Called hubcentric rings, you should definitely invest in some.
