Had my car MOTd today. Comments from the tester was I had 2.5mm tread on the rears, but 4mm tread on the front, with all four tyres showing even wear across the tread (tyres are Bridgestone Potenza RE050A). All four tyres were change at the same time (approx 15,000 miles ago), and they've not been rotated since new. My query is how come a 'predominantly' front wheel drive car has ended up wearing the rear tyres more than the fronts. It the wear was uneven across the tyre, I would put it down to incorrect rear suspension settings etc, but to wear the rears evenly across the tyre more than the front seems strange to me. Any thoughts? Thanks.
