I don't know , maybe they are available in Australia but they don't seem to be available here. The dealer checked the main supplier in the UK and they said they were discontinued. I checked the Dunlop website before ordering and it was the Australian website that listed them so I figured that they should be available here aswell, but sadly not the case.
I did notice they were removed from the RGV.C0.UK (tuning works) website some time ago but didn't think they were discontinued.
Anyway, I ordered a set of BT090's yesterday, just happy that I can get an 18 inch rear tyre right now because all week I thought I was fooked.
Anyway, thanks for the info. Maybe the dealer has some deal going on with Bridgestone.
