Two flat 20" tyres at the same time on my HSV wagon after hitting a pot hole on the South Eastern Freeway. Two other cars already by the side of the road with damaged tyres when l pulled up. A Mercedes with run flat tyres had sufficient suspension damage that it was undriveable and it cost me over $1,500 to put right. Vicroads wanted nothing to do with it denying any liability, however my Shannons insurance policy went some way to meeting the cost.
