A: This is a question that none can give a very accurate answer. To begin with, we have to know how many cars, vans and trucks are there in the world. Based upon the statistics by US Publisher Ward’s, more than 1.1 billion motor vehicles in use as of the year of 2010. This number is actually increasing every day. Presently, there are 1.4 billion cars in use worldwide, among which 1.1 billion are passenger cars. If only 3 % of cars have been considered damaged with some kind of bent, that number represents 300 million bent rims out there.

A: When one of the wheels is bent on the vehicle, it may cause a number of problems when to continue to drive without repairing. Every time the flat spot his the road as the rim runs, the vehicle has to react with some kind of vibrations, which can lead to problems with alignment, tire pressure monitoring system, ball joints, and more. It will also cause uneven wear to tires. For the rim is bent seriously, the vehicle can be used for normal driving.
