So here's my deal: I've had my summer wheels with new Kumhos put on a few weeks ago. When I had them put on I immediately noticed way too much shaking when I got up to 60-65 mph. Took it right back to the tire place and had them re-balance all the wheels. Took the car back out, and it was somewhat better but still not quite all the way gone as far as the shaking at 60-65. I thought maybe it was something that would play out after I drive the car enough. Drove the car for a week and still not any better. Took the car to a different tire place, had a four wheel alignment and had them re-balance the front wheels because that's where it seemed I was getting the most shaking, in the steering wheel. Took the car out when they were all done, and it was the same. Brought it back and told them that it wasn't any better and they suggested hub spacers for my wheels that I had bought from them and they never installed when I bought the wheels from them. Couple days later had the hub spacers installed, and took the car out. No difference. Still shaking at 60-65. Called tire rack (where I bought the Kumhos from) and explained my situation and they shipped me out two more Kumhos to replace the front two that I thought could be defective. Took them to the tire place with my fingers crossed. Had them mounted and balanced. Took the car out. No difference. Still shaking at 60-65. Ready to give up. What else could cause a rough ride besides wheels/tires? Help me please!

Is it only happening at 60-65 MPH or are you noticing it at lower speeds?

I do notice it somewhat at lower speeds, and I do have some pulsation when braking that I figure is my brakes needing to be replaced soon, but I notice it the most at 60-65. Just not the nice smooth ride I used to have.

The only other thing I can think of is a torque converter problem. When mine locked up it would case the care to shake violently. If you aren't actually feeling the car wander around when it happens, it might be worth considering.

Check your control arm bushings. They may look good, but one under load they may not be.

Also check your CV joints as well. Those can cause symptoms as those speeds.

when i got new tires put on by pepboys their idiot tire changer failed to clean the corrosion off the wheels and with in one day i heard two wheel weights fall of. took it back, they tell me the guy who did my tires quit the next day. so they balanced all my tires i think 3 out of 4 were off. but they still didnt clean the tires took it to a different place and they sealed and balanced all 4 cause they were still off

It's amazing how incompetent some people can be. It also gives the shop a bad mark because of it.

Its kind of frustrating when things don't work out right the first time. Maybe the guy just wasn't trained correctly. The belle tire and discount tire shops don't and won't clean the corrosion off of the inside of the rims. The policy is to sell new rims. The health hazards that the aluminum oxide poses to employees is most likely why they don't do that. The ultimate solution is to have the rims sand blasted and powder coated. Grinding the corrosion off of the inside of the rims and using bead sealer is only a temporary solution, but it does last a considerable amount of time. Back when I worked at the service station I never had one come back. With that being said, the roads in this state pretty much eat suspension and tires, so that may be why.

The hub spacers kind of get me. Are they "universal" or not?
I used "spacers" before that were nice aluminum & supposed to be balanced but were far from it....caused all kinds of chaos. Hate to say a 3rd opinion is needed, but.....

the hub spacers are universal and plastic. the wheels are aftermarket, so that's why they suggested them, i guess. doesn't matter, they didn't help, but they didn't hurt either.

something to think about with physics in theory in order to vibrate it has to kinetic energy. front end parts not so much. if this just happened with change of tires what else changed? where they new rims? is a rim bent? did you rotate the new tires?

that's what I've been going over in my mind since I put them on. Didn't have this problem last spring/summer with these wheels on. I had 3 different kinds of tires on the wheels as well. They ran fine. The rims were bought brand new last spring. The first place I went to to have the new tires put on is very good about pointing out bent wheels, so I know it's not that. Don't mean to sound ignorant, but how would I rotate brand new tires?

are they directional? but since they are brand new you could just swap the fronts to the the rears
