Vibration over 75mph... what’s going on?

Just got new tires on Dec 23. Now, when driving, I notice a bumpy ride and vibration over 75mph, especially when accelerating. I pushed it to 80mph, and it sounded like a card in a bike spoke coming from the driver’s front. Any ideas? Could use some help with this.

Take it to the place that installed your tires. It could be that they’re unbalanced.

I will. Unfortunately, I can’t get there until next week. I’m on a trip and need to get to my destination and back. It’s about half a day away. It’s ironic since I had the tires and servicing done to make sure my trip was safe.

Make sure all your lug nuts are in place and torqued to specs before going over 80mph again. If you have AAA, you could ask them to send someone to check them for you. I had a friend who nearly rolled his van because a mechanic left a lug nut loose. Luckily, he wasn’t hurt and received compensation from the service.

I just checked the lug nuts, and everything looks fine.

There are a few possible reasons for this vibration…

  1. You may have lost a wheel weight during balancing. It could be that it wasn’t attached properly. You can go back to the place where the tires were balanced and get them rebalanced.

  2. It’s possible the balance job was done poorly, in which case you can ask for a rebalancing at the same shop.

  3. If the balancer was faulty, going back to the same place won’t help. You would need to go to a different place for a proper rebalancing.

  4. Sometimes even properly balanced tires may still cause vibrations because of mismatched wheels or tires. You might need to go to a place with a road force tire balancer.

  5. It’s also possible you just got a bad tire, and it could be replaced under warranty.

If you trust the shop that installed your tires, it’s worth asking for a recheck. If that doesn’t solve the issue, you can explore other possibilities.

I can’t do that right now since I’m in a different state, but I need to get to my destination first and then back home.

I put Michelin Defenders on my Sienna. From what I’ve heard, a lot of people use them on that model.

Anyway, whatever speed you think I should go, I just know that I’ve never had this issue before, and I’ve driven this vehicle for 7 years. I’ve driven at 75, sometimes 80, but never had this issue before these new tires.

Balancing usually costs about $50 at a tire shop or mechanic.

Yeah, I’ll have to get to my destination first, then find a shop. I’m guessing everything’s closed tomorrow because of New Year’s Day.

What year is your vehicle?

We had a 2019 model that shook and was hard to steer when both cruise control and lane departure were activated together. It felt like the car was trying to steer itself, and it was really unsafe.

@StarlightSpecter
It’s a 2017. No fancy features. Cruise control works fine. I’m keeping it between 65-70 now.

@StarlightSpecter
Shaking is definitely not normal. Toyota’s lane assist and centering aren’t great though. It’s honestly pretty bad.

This happened with my 2011 Sienna. I took it to the shop, explained the issue, and they said the tires were wearing unevenly, which pointed to bad suspension.

We replaced the suspension and bought new tires. Still vibrating. Then we realized they put two different-sized tires on. Fixed that, still vibrating. Then we realized the tires weren’t rated for the weight of the van. Fixed that, still vibrating, but less. Finally, I decided to just drive at 70 and deal with it.

A while later, I took it in for an oil change and mentioned the vibration again. They told me it was the drive shaft, but that I could keep driving it for years before it becomes a problem. The very same day after that, the vibration stopped. No idea what they did.

@Hollis
Wow, that would drive me crazy. If I were you, I’d find another shop.

Well, obviously, but they had to fix their mistake first. What I’m saying is it might be your suspension or your drive shaft.

@Hollis
Thanks! I really hope it’s not. I’m taking it to another shop in a different state, so I’m hoping they’ll catch something the other shop missed.

Are your tires run flats? I replaced mine with regular tires because the vibration wouldn’t go away until I swapped to a good quality non-run flat tire. I went with Goodyear Assurance.
