Hoping someone can help.
Recently had my front tyres swapped with my rears as they were getting low on tread (and I want to change all 4 together). They are Michelin PS3's. approx 3mm rear and 6mm front. The fitters swapped them front near side to rear off side and vice versa.
Since then I've noticed a droning noise from the rear, and I'm inclined to say near side but can't be 100% on that.
When I turn right, on a roundabout for example, it fades away. Straight ahead and left turns its remains there. Once over about 40 mph it disappears. However, this could just be road/wind noise blocking it out or the frequency changing as it does vary with speed.
Is this the tyre wear issue that is well known, or a bearing failing?
Any advice appreciated.
