Hi everyone, here is my situation... After replacing the tires on my LS and multiple road force rebalancing attempts at the dealer and elsewhere, my car continues to have a steering wheel shimmy that is driving me nuts.

At this point, the next logical step would be to try a set of tires and wheels that is known to be vibration free, but my dealership has no LS 460s in stock. Would anyone here be willing to help me out? I realize it's a bit of a gutsy move to ask, so I understand if people are not too comfortable with the idea of letting me drive my car with their tires and wheels on it, but I'm running out of options so I thought I'd ask.

Thank you in advance. The car is currently at the dealership in Metro West.

 

Im running a tire shop in auburn ma. Sound like a tires issue, what kind of tires did u buy?

 

It definitely feels like a tire issue, given how it's a function of speed, etc., and I hope that is the case, though the shop foreman at the dealership has some doubts about that.

Just this morning I tried a local shop that owns a GSP9700. They took their time to check through everything (and charged me an arm and a leg too), and the vibration is marginally better but still very much present at the same speeds as before, so I am at a loss (not to mention a bit tired of dealing with this).

The tires I put on (to answer your original question, sorry!) are Michelin Pilot Sport Plus A/S.

 

really stiff tire though, could be a manufacture defect. If you jz bought it, I recommend to bring it back and swap it out. Not every tires are perfect form to every rims. I did a ls460 recently and I put on dunlop sport signature, so far so good. My customer havent got any issue with it.

 

Does the place you bought the tires from have a 30 days test drive policy ?? Because we do at my company and our customer love it.

 

I actually bought them at the dealer, something I had never done before, but the price was reasonable, and I didn't have much of a choice as I needed new tires in order to pass inspection.

We could probably pursue something with Michelin directly if we knew for sure that the tires are bad, and this is why I would like to try good wheels and tires on my car to see how it goes, since road force measurements seem to be fine.

 

If Michelin does Warranty ur tires , i would recommend to go with the Primacy mxm4 models. It's a better fit for the LS

 

Thank you for the suggestion. I like what I read about that tire, but unfortunately they don't seem to make in the right size unless you have 19" wheels.
