During a rainstorm a few weeks ago, I managed to spin my Toyota 4Runner and smack the drivers rear tire into a curb pretty hard…hard enough it broke the tire seal and went flat. After getting the car to the tire shop, they just re-seated the tire and said it was balanced and all in good condition. However, now when I drive, I get a rythmic “road noise” kind of sound that I never had before. I’m not sure if the tire is damaged internally, or if some bearing was hurt when I smacked the curb. Trying to figure out if it’s a tire problem or a mechanical problem. This is a sound of the car in motion…you the rhythm of the noise moves along with the speed of the car.

I really question that tire shop’s diagnosis. It sounds like you bent/damaged the rim so I would go to another tire shop to get it checked out. ---

You might be able to find out by jacking up the corner of the vehicle and spinning the wheel. A damaged bearing should be noisy. If you hera no unusual noise, you could try rotating the tires and see if the noise moves. ---

In this case I like the bent rim theory. If you have allow wheels I really like the rim theory. Consumer grade allow wheels are not as strong as steel wheels. ---

You may also have permanently damaged the sidewall of the tire. Although it has aired up , it will never be the same. Much like creasing a piece of aluminum then bending it back straight again, the crease is always there and it’s stuctural integrity is forever compromised. ---

I just posted a similar question on here. After listening to the file, the sound is the same as my 2000 Camry after hitting right front tire on a curb. I removed the wheel assy and still heard the noise. Not sure what is the cause but if I get a response I’ll share. ---

You damaged either the tire, rim, bearings, or axle. Put on the spare, if the noise goes away it’s tire or wheel. If not, it’s bearings or axle.
