Vibration due to MRR GT350 rims

[NothernVAMustang]

I have a 2017 GT automatic with MRR GT350 wheels. I've been having a vibration issue over 70mph. The dealer put back the stock wheels back on and there is no vibration. They balanced the wheels and did road forced balance and they are saying the tires are good the problem is the rims. Can you guys help me. I don't know what to do

First and easiest option in my opinion would be go to another shop. I once had a "balance" done twice at one shop and the car was still shaking. Took it somewhere else and smooth as glass after that.

The wheels were balanced a month ago by a different dealer

What was the radial readout?

I called the dealer about radial read out they said the machine doesn't give them that

Damn ok

Is there a visable bend. warp or anything they can see?

Have them spin the wheel with tire off and do a simple visual if possible

the last time i had this problem they had to finally take the tire off the rim to look inside and they found out there was a belt separation in the tire... thankfully continental replaced it under their warranty as a defect.

The rims are in perfect condition! No visible damage

Then could be the tire brotha.

Are the wheels hub-centric to the car or do they require a hub ring to make them hub-centric? If they require a ring and it is missing that can give you issues with vibration.

I think it's the tire...

The MRR350s are hubcentic, no ring required

Sounds like it's the tire meng. You should have all of them taken off the wheel and inspected separately.

Take it to a reputable tire shop that has a newer Hunter road force balancer. They should be able to tell you where the problem is. If they can’t, then they don’t know how to use their equipment.

If the assembly balances out ok but you still feel vibration there’s only a couple things it can be. First and most likely is a tire out of round or a stiff spot in the sidewall. Next would be a wheel out of round. Even if a wheel looks round it could be a few thousandths off and give you vibration issues.
