I just wanted to see if anyone else had experienced the same as me with their rear tyres as I haven't seen anything on the forum about it and thought it may be useful to start a topic incase anyone else runs into the same issues!
When I bought it, the car had done 26,500 mile and had what I presumed to be the original dunlop sport maxx tyres fitted to the rears and the garage had fitted some budget tyres to the front (can't wait for them to wear out and need replacing
) When test driving, I had noticed what I thought was a very slight wheel bearing noise and thought nothing of it, thinking it might be related to the cylinder deactivation. Anyway, the noise got increasingly worse as speed increased - especially around 50/55mph (with a slight vibration too) until at around 34/35k, and with the car counting me down to its service, I took it to the local mechanic I know to give it a once over and book the service, asking about a turbo noise (air release noise - no issues) and this suspect wheel bearing noise. I had noticed the rear tyres had a weird dust pattern on them, as in alternating diagonal strips had dust and others none. There were also flatspots on the inner part of the tyre, flat for a couple of inches then loads of tread again then flat again etc... I pointed this out and he immediately said that was causing my "wheel bearing" noise. I believe it's called "sawtooth wear" and even tyre manufacturers don't understand how it happens but it is more common on the non-driven wheels. I had two new tyres fitted (originally I wanted PilotSport4 tyres but with these on back order I went for Pirelli Pzero GT tyres - look amazing) and the noise is gone and we have silence in the cabin and a really smooth ride!
Here is a video showing the irregular tyre wear. Looks more like a 50p than a tyre
