I recently acquired a set of Coupe wheels in mint condition with almost new tires. I put them on my saloon yesterday. I have to say they look well nice.
Now, I was expecting a little more road noise, but by God, I now sound like a jumbo on the runway just before take off

I have two Michelin pilots, almost new that I put on the front there appears to be no noise from these two.
Two Linglong on the rear where the noise is coming from.
My camber is hideously bad on the rear wheels.....which is a on my "to do soon" job list. The wheels I took of were bald on the inside and almost good as new on the outside!
My theory is the road noise is the result of wider tires exasperating the camber problem. i.e. they are almost on the inner tirewalls......
However, it might just be cheapo tires on the rear that are noisy, but I'm stuck on my theory because they just can't be that noisy...can they?
Anyone else suffered unbearable road noise after adding a bit of tire width?
