My sister recently hit a curb in her lil saturn. She managed to shred her front right tire and dent her back right rim. I went to a junk yard and bought her a replacement identical rim. We replaced both tires on the right side, and rotated the new tires to the back. Now there seems to be a bump, roughly every rotation of the tires. I told her that she needs to get the front ones replaced within the next month. I think the bump is probably from rotating the old tire on the back to the front since I doubt if she has ever rotated them. My only concern is about wheel weights. The wheel I salvaged from a pull apart had a wheel weight on it of 6.2g, and the stock had a 5g weight. I was noticing another wheel had a smaller weight than both the other wheels, so I'm guessing that the wheel weights are specific to the rim, not the car. Is that a correct assumption? Or could I be risking damage to her car with my cheap fix?

 

Take the car to the tire shop and get those tires/wheels balanced ASAP. The weights are specific to the tire and wheel as assembled.

 

okelly dokelly, thank you sir. And to make positively certain, The Tires were installed by professionals, but her vehicle wasn't present at the time. If they are balanced as a tire and wheel combo, then I would reckon it was done at the shop already before I drove em home and bolted them to the car.

 

One would think that would be a safe assumption.

Rotate the tires again, and see if the bump moves. If she hit hard enough to tweak a wheel enough to have to replace it, she may have damaged something else as well. Rotate the tires, if the bump doesn't change, need to start looking for another cause.

 

great plan
