Cooper S 18" Alloy wheels problem
I own a 2007 Mini Cooper S, I have changed my original set of 17" Mini Cooper alloys for a set of Kahn RSV 18" wheels with 215/35 18 Runway tyres. The alloys are 7.5J 4x100pcd ET 45.
I brought them second hand with one of the alloys dented on the inside rim, so I brought a replica 18" RSV rim to replace the damage one and swopped the tyre over. I have now fitted them to the mini a they look great. The problem is that they are quite noisy and they make a slight wobble on the steering wheel at around 50mph. I put the sound down to the cheap tyres, I put the two tyres with the most tread onto the front. Two of the wheels have just been balanced as one tyre was swopped over and the other had a nail repair.
Is the wobble caused by the two alloys needing re balancing or does the tracking need doing as they are bigger and new in the car?
Any advise would be great.
