My car vibrates slightly after buying new tires. What do I need to do about that?

The shop did not balance the tires correctly.

Billy Bob's fly by night shop may still be using the old "Bubble Level" balance device. These are not very accurate for higher speeds.

You need all four tires Computer Balanced on a Speed Balancer. And specify to the tire tech for 70mph. The computer will tell him the size weight he needs and rotation position of the tire to install it (front or back). Assuming the tire tech actually knows how to work the balancer.

New Tires Vibration

If the vibration only happens while driving straight, your new tires are probably out of balance. I think you're supposed to take the vehicle back in after your first 100 miles on the new tires to have them balanced again... if you didn't do that, that might be a little bit of the problem. Take your car back to the place you got the tires, or one of their other stores if you went to a chain. You might have a warranty or something that will have them look at the tires, but with only 2 months on them I would expect the shop to look at them at no cost. They should guarantee their work and fix the problem. Meanwhile, check your tire pressure... that "egg shape" you mentioned sounds like you're low on air.

The most likley possibilty is that the tires aren't balanced, or are incorrectly balanced which would definatly vibrate at 60-65, go back and and have the tires rebalanced. The best machine for balancing is definatly a road force balancer if you can get them done on one of those,,,DO IT...

No. Call the tire. Tell them the problem. Say that you want them t inspect all of the tires and take the car for a test drive. Ask if you can have an appointment to take it back in. Go back there and watch them closly.

Did you have your tires balanced? This is when they spin them on a machine at different speeds, including highway speeds and then balance them by attaching weights to the tire rims. This prevents / solves the vibration you are experiancing.

You need to have the wheels balanced not aligned. If it pulled to one side or another, that would be alignment issues. yes take it back and have the wheels balanced it that don't fix it you could have gotten a bad tire, maybe it bubbled up or something, go back and have it checked.

sounds like they need to be balanced properly

they did a bad job

around 50-70 is where the balance becomes an issue

perhaps they skipped it, or it was somehow optional

You need to go back to the place you bought the tires & have them rebalance them.

Definitely go back and see them. It is possible that you have at least 1 faulty tyre.
