Every brand of tyre has there good and bad models, the Dunlops that were on the AU XR's were a crap tyre, whereas the Dunlops on the BA XR's seem to be much better. I had a set of Dunlop Bathurst 1000's on my 16" XR rims on my EF and they are by far the worst tyres I've ever owned, impossible to balance properly by more than one tyre dealership wore badly, gripped hopelessly, I changed them to a set of the cheapest Kuhmo tyres when I sold the car and they made it feel like a completely different car no steering wobble, better ride and better handling. Anyway my point is tyre manufactures make tyres to suit a wide variety of budgets and in doing this quality suffers, one tyre dealer once told me the rule of thumb is to never buy Australian made, whether this is true or not who knows. The MOTOR mag tyre test is a worth a read, I think they should be doing that again soon.
