Well I’ve been chasing this problem with my 18’s for some time. I’ve roadforce balanced them, checked runout, and put on hub centering rings but I still can’t seem to get rid of the vibration I have over 50mph so i’ve finally decided to scrap those rims/tires and go with something new. Cheap rims/tires made it for 3 years but now I want something different. Heres one set that i’m looking at: http://www.wheelmax.com/product.asp?ProdId=10062
Also I want a good performance tire preferably one that isn’t known for excessive road noise because the cheap tires I have right now are ungodly loud. Any suggestions would be appreciated of wheres a reputable place to buy rims.
