Vibration at speeds over 80 mph

Out of round is a condition that may have happened when the tire was made, so they should check for that as well. The old way to test it was jack the wheel up, put a coke bottle next to it touching the tread, rotate the tire and see if the bottle moves or falls over. I'm sure they have better ways now!

javapro: A vibration that's always there at a certain speed would be easy to duplicate with a service rep aboard. Only thing is....not sure they want to be test driving it at over 80mph!

I had the exact issue with new standard RX I purchased in October which came with Michelins. Slight Vibration in pedal/seat.this would occur at various speeds from 60-80mph. Dealer replaced 2 tires saying they were unable to properly balance(out of round). Got car back, better but not gone. Dealer then replaced one of the new tires saying it still wasnt right.Foreman took ride with me again. I still felt slight vibration but said I would give tires some time to break in and well address later. I wound up bringing car to Direct Tire. They roadforced balanced two rear tires. Both 1/2 ounce off. Now perfect. Cost me $50 but I knew it would be done right. Dealership rushes thru this stuff to get cars through the service dept. I dont think they roadforced the two new tires they installed.

Years ago I purchased expensive Pirelli P7s for another car and one of them was "out of round". It happens, quality control must not be a tyre manufacturers strong point - after 12 months all four tyres started peeling on the side walls which they replaced under warranty. What's that saying "You get what you pay for" - yeah right.

yes once u say vibration at highway speeds first thing they will check is balancing. Take tech for test drive(you drive). That way you can get up to 80mph and demonstrate. If they repair it take it for another drive before you accept back.

Just google it or youtube. Tires are put in a machine that simulates it riding on road surface. Its a bit long to explain but its basically a much more precise wheel balancing machine and often helps tech identify and fix vibration issues regular balancers cannot. It is dependent on the skill of the operator as well.

So, I had to go in for my first (5K) service recently and mentioned to the dealer my vibration issue. Of course, they couldn't replicate it because they wouldn't drive over the speed limit. After some back and forth they finally agreed to road-force balance all the tires for free as part of the warranty. The mechanic who did the balancing told me that all the four tires were pretty much balanced dead on. I think he said one was slightly off. He rotated them using the X pattern as well as part of the 5K service. I drove my car at 80+ mph a few times and even though it seems like I don't feel the vibration as much it is still there. Could it be because of the Bridgestone Ecopia tires that I have? I've been reading in this forum that Ecopias are much harder and noisier than Michelins. I had Michelins on my previous RX (2016 RX 350) and it drove smoothly even at 100 mph.

When you take it for an 80 run is it always on the same road - could the road be the problem.
I mention this because a freeway I frequent has a section that must have very small undulations that makes the car feel like it's vibrating badly, the first time it happened was a bit scary, "what's wrong with the car", but I'm use to it now.
