My car had vibration problem after I changed brand new tires and rims. It made me mad last a few months, and I did what ever I can do to fix it. I even don't remember how many repair stores I tried already, how many wheel balance I did already, how much money and time I spent for this problem already. Another result is that I became the tire/wheel professional finally. The problem is the multi-fits rims.
So I'd like to tell everyone here, NEVER use multi-fits rims. they are all crap. They don't match the industry standard. The simple reason is that the central hole of the rim is much bigger than the wheel hub to fit multi-cars, so the centre points of the 2 circles may not at the same position, that is the obvious reason to caused viberation. But the thing really suprise me is that there are few people know it, the people means those tire/wheel professionals, even in business over 20 -30 years and have all kind of certificates. There is one way to fix it, to use the hub centric rings, but again, most prefessionals don''t know that.
Another good recommendation is to use GSP9700 balance machine to do the tire/wheel balance, there are few shops have it, some big new car dealers have it, it's the best one in the entire industry. There are 3 ways can cause viberation, the regular balance machine can only resolve one. GSP9700 can resolve 3 of them except the muli-fits rims problem.
Hopefully my 2 cents have a little help for most innocent people.
Thanks!
