Called up Advance Tyres in Richmond and got the following prices

Dueler RFTs (on special)
$425 fronts
$450 rears

Dueler Non-RFTs
$400 front
$415 rear

Atturo
$200 front
$279 rear

Has anyone tried the Atturo's? Bloke from Advance said they werent as good in the wet as the Bridgestones and were noisy. The price difference though is pretty substantial.
