Problem

[AWDthis]

So i decided to rotate tires, the front are baldy and the rears are ok for another few months. After i get everything changed (front left to rear left, rear left to front left) I get this weird noise whenever going past 20mph, as if the wheel was touching something as it is rotating, like a huming...(braindead
Any help PLEAAASSEEE thanks in advance!

Humming like brakes?

humming like "wah-wah-wah-wah-wah" but pretty loud, read something on the internet about tires cupping but i have no idea what it is... afraid to go anywhere like this

Im going back to my car and rotating all the tires back to the original position see what happens...maybe its just time to replace all tires..Ouch $$$

Fixed..for now..my rear tires are "cupped", the inner border has some ups and downs, weird it has no effect when its on the back but once you swap it to the front, hell breaks loose. So can anyone recommend any tire that would be an upgrade over the stock potenzas?

Cupping is kind of a hit or miss thing. Some tires are more susceptible on some cars for whatever reason. It does seem to be less audible with some tires than with others when it happens. Hopefully someone with more experience with the MS3 can give you some specific advice about tires on the car that are less susceptible to cupping.

Poor alignment can cause cupping, so you might want to have the dealer check it. Make sure they check all 4 wheels and not just the front. And don't trust the alignment that the tire place offers to do for you. They usually are wrong, in my experience at least.

I have found on other cars that frequent rotation seems to help. I rotate every time I switch from summers to winters and vise verse....

Yeah thats what happens when you buy a used car Def. tires are shot, good thing because I was beginning to think something else more expensive
