When I bought mine one of the rims was bent and causing my steering wheel to shake! I was really happy when the dealer replaced the $700 rim for free😁

The dealer I bought that car from are jerks the car ended up needing a lot of work and when I bought it the car had a cracked rim found out someone put jb weld on it, I ended up going with all new wheels and tires because the one that was cracked was bent also. But still didn’t fix the issue. I have an appointment next Friday at the dealer they will probably keep the car for a week 🙄

Yikes. The bent rim makes me wonder if there is some deeper damage to the suspension. Luckily it sounds like its covered by the dealer, best of luck getting all of that sorted out.

Just for reference. I Mic'd a set of stock rims (on my balancer) when I was having vibe problems and they were almost dead nuts (mine vibes turned out to be stock tires).
Hence why I bought a second set of stockers, vs some cheaper junk for winter use.

I still get vibes on cold tires that have sat. Many say tires don't flat spot, but that is BS. I have less than a mile and I can be on the highway.
The first couple miles @ freezing or below is a vibe fest over 60, after car sits for couple days in the winter.

Current tires do not flat spot as bad as the old nylon tires did, however, agree the new ones still do. High performance tires will flat spot more than middle of the pack tires. Flat spotting disappears within 5 miles or so,

I don’t think it would do that, it wasn’t noticeable at all and it balanced out perfect, it wasn’t a huge bend, only noticeable when balancing. But I could be wrong about it damaging another part, lemme tell ya this car has a mind of it’s own it’s always had some type of problem since day 1 😂

I agree with 19Sport - it’s a long story but I t-boned a car with my 1994 F250HD at about 50 mph. Tore the front clip off a Chevy Malibu and smashed the front right of my truck. Bent the bottom leaf spring to the ground and punched the front frame horn through the steel bumper. Three weeks later my truck is repaired but more vibration and bump steer than usual (those leaf-sprung TTB trucks had terrible ride quality). Turned out the right front leaf spring rear mounting bracket was folded back all the way to the frame, nearly 2.5 inches! Everything went back together and the truck was aligned within specs but the leaf, shackles, hangers were all at max length so it was basically immovable. Good thing it was summer and I didn’t put the plow on it. Like I said, how to make a short story long, but just because they can put the parts back together and everything fits doesn’t mean it’s right.

Did anyone check to see if the brake rotors were bent. You don't know what happened to the car? You can't just visually check them.

Do you have a short commute? I had this to an extent with the factory Good years. Now I got Conti DWS and its still there. balanced twice. BUT after about 5 minutes it goes away. and on one certain point on one certain highway it still happens. I chalk it up to Flat spots, its worse after the car sits in hot weather. Another huge thread about this on here. Some guy said its normal and called tire nibble. I still say flat spots. My buddy with snows for the winter says it doesnt do it on his snow tires. but does on pilot sports really bad until warmed.

You could buy a dial indicator pretty cheap at harbor freight Id say then check runout. Brake problems usually only effect anything while braking.

Some tires are susceptible to flat-spotting than others do there's no one blanket answer there. For example I used to store my Miata all winter and never got flat spots.

DG any update on this ?

Tire brand makes a big difference, Michillen's are smooth no matter how long they sit, or temps. Buy some cheap off brand china junk, and they will feel like dog doo doo all the time. Another thing that will cause tires to feel out of round is tire pressure. I bought some General Altimax's for my 13, so when I got he Sport I threw them on it. I had the morning vibration going, but once I drove it about a mile n half it was good. Issue is the 13 tire sensors are different from the 17's so I haven't had my tire monitor system working. One day I check pressures and find one a bit low. go around set them at 37lbs and no more vibration in the morning. Seem like low 30's will cause it till about 35 36. Guy that runs our office likes to sell cheap tires a lot, and I always tell him they will complain.

I could never run my tires @ 37lbs. I can't even stand them at the stocker pressure of 39. I run mine at 41/42. If they get below 41 I can tell. Especially, when cornering.

 

[Shawnski]

I typically follow the tire manufacturers guidance for air pressure, but in relation to the auto manufacturers instructions. So if the tire says 44 max. psi and the car maker says 36 psi, I will start at 40 and watch and measure my tread wear often. I’ll adjust psi upward while observing wear, noise, handling, and ride comfort. After I get to know a certain brand/model of tire and like it, I’ll continue to use it and follow what I’ve learned. I run my Continental DWS 06 tires between 41 to 44 depending on my travel schedule and ambient temps; higher pressures for highway marathons and/or hot weather. I typically get at least the tire manufacturers advertised tread life and I think I do all right on fuel economy too. Ride comfort and noise should be more of a function of the tire design and engineering than air pressure, though not exclusively. But it seems to me that non-premium automakers tend to choose OEM tires based not on prioritizing quality but rather on how much they cost first, unless it’s a dedicated performance or heavy-duty vehicle.

Can definitely back up the statement that Michelin’s are smooth. Put on a set of primacy mxm4’s back in October and they’re nice. They perform great in the snow as well!

Not all Michelins are made equal?

Every morning on my way home from work after sitting overnight in 20-30F weather, my Uniroyal's will have a little bit of vibration over 30mph that lasts for maybe a mile. Maybe Michelin uses a different compound for Uniroyals?

Tire Rack has a nice little informational guide on flat-spotted tires on their website “Tech Center” heading.

Sorry for the late response but no I have a decent commute whenever I drive my car I go atleast 20 miles

Yes actually, it went into the dealer and come to find out another two of my wheels were bent, so I replaced them. They also found that my differential was grinding so they replaced that and an axle, and they also found my muffler has a crack in it. The car doesn’t viberate as much as it did but the steering wheel isn’t 100% smooth on the freeway. They also said my rotors need replaced, I also haven’t fixed the exhaust yet but when I do that I will give another update!

It also doesn’t feel super unstable anymore, it also recently sounds like the rear shock mounts are going soon they are making some noise back there. I’ve taken it in the dealer for that too but they told me everything was fine
