It goes without saying that unlike other car wheel problems such as wheel alignment that can be done with the car intact, you can’t fix a bent rim with the wheel mounted on the vehicle. It has to be removed and the rim separated from the tire as the process involved heating that may destroy or wear out the rubber tires.

Heat and hammer the bent area

Using a propane blow torch, carefully heat the bent area with the full bore flame for two to three minutes. While hot, place a wooden bar on the rim and hammer it against the curved lip.

Avoid hitting directly into the hot rim as the pressure from such an impact might crack the rim. Rather use a wooden block as it helps spread the impact on the wheel thus reducing the level of impact by spreading it over a larger area on the wheel. Repeat this process until the damaged part straightens back to its original shape.

Check for a toned roundness using a dial indicator

You don’t just want to fix your rim because the bend is displeasing to look at. You also want to avoid the motoring challenges such a bent rims cause such as unnecessary vehicle vibrations while on the move.

The best thing about learning how to fix bent rim using the hammering method is that it is inexpensive and also gives you full control of the correction process. It is nonetheless advisable that you engage the services of rim repair expert, especially if you have little to zero experience with the hammering process of fixing car rims.

Other methods used to fix your rim

Apart from the hammering process, you can also consider learning how to fix a bent rim using the cold rolling or the hydraulic assistance technologies. With the cold roller technique, powered rollers are pressed against the wheel as it spins on a lathe. The main different between hammering and cold rolling is that the latter doesn’t require heating in straightening bent lips.

Such forced straightening techniques often result in rim cracks. And even if the rim survives the crack, the process softens the wheel thereby predisposing it to more bends from slight impacts.
On the other hand, the hydraulic assistance technique involves placing the rim on a rack and identifying variations on the rim roundness using a dial gauge. The wheel is then heated and using the rams on the rack; a skilled operator can then straighten out the bent areas by pressing them inwards or outwards.

The process is a technological improvement of the hammering technique. However, it isn’t readily available to the customary wheel straightening market as it remains proprietary innovation of selected wheel dealers. You need check car repair centres near you.
