For the last 3 days I've been noticing a weird wahwahwah noise when driving, about 60mph. On the way just now I pulled off the motorway incase it was the road surface and while I was going through a village the engine check light came on. I pulled over and switched off and became aware of a "hot plastic" smell. Getting out and having a nosy around it turns out my front O/S alloy is very very hot, and it's the tyre I could smell. What dya reckon guys?
