This depends on the damage, material (aluminium, steel) and design. If the damage isn't severe it is definetly cheaper to fix at a auto-garage with the proper equipment than buying a new one.
I cracked an aluminum rim. It was split about 3 inches and dented it. I found a garage that would staighten it, reweld the crack, and grind it back smooth for $75. A steal for me as this rim wasn't made anymore. Oddly enough the shop had no real advertising, everyone knew them by word of mouth. Hope this helps.
It depends, if is a bike, probably want to get it fixed, but on a car, i dont know. On a bike it probably would not fail
Yes, it is.
Yes
Yes, it can.
If it is severely bent the side wall in that area may be damaged, but if it is just a curb hit, the tire should be fine mounted on another rim. If it is a steel rim, the tire can be taken off and the lip of the rim bent back into place and used.
Yes
Regardless of what any tv show or anything tells you a bent frame can be fixed as long as it is not totalled. The car will still work the same and be just as safe.
You've hit and run over something with the car.
Yes, I usually buy old cars and keep them a couple years. Every one has had a bent rim
Probably not. It may be worth the five or six dollars to try.
You may have a bent rim or damaged the tire.
If the rim is bent, the rim needs replaced and is the problem.
