Slight Vibration At High Speed -- New Tire?

[WattsHappening]

Hi all,

One of our Model 3s experiences a slight vibration at high speed. It starts at around 75mph and is pretty noticeable at 80mph.

One possible reason is I had to replace one tire after around 6,000 miles due to to a nail in the shoulder area. I believe there was about a 2mm tread wear when it was replaced. So one of the front tires has slightly more tread than the other 3 tires. I asked about the tread wear when I purchased the new tire, but was told it wouldn't affect the drive.

One thing I can say with certainty is the vibration is not just in my head. We have two Model 3s, and the other one is smooth as butter at high speed.

What say the experts? Can the difference in tire tread cause a slight vibration? Or should I take it in?

TIA!

I have the same issue on mine as well. I was thinking about to take to a tire shop and see if they can find out anything. But I'm also afraid that they just want some business and tell me to replace all the tires.

2 mm tread depth difference is the maximum difference between tires that's allowed, so that shouldn't be an issue. The suspects are:
1. Balancing was poor.
2. The tire was not seated properly on the wheel.
3. An actual tire problem with the new tire (unlikely but possible).
4. A wheel issue (also unlikely as there was no issue before).
5. A new tire should be driven gently for 300 miles. This allows the mold release to be worn off and also reduces the chance of the tire slipping on the wheel (because of the lubricant).

Steps to take:

1. Remount the tire paying special attention to proper lubrication and seating. (and rebalance).
2. Get the tire forced balanced (on the car balance).

@Jerry! Thank you; very helpful information.

I guess a trip to the tire shop is in order.

@Wesley, good luck; I hope you are able to resolve your issue.
