Not that any 300C members here have anything to worry about. 300C came on the Australian market in 2006. Saw it on TV tonight saying tyres are really only good for 6 years as the rubber compounds deteriorated over the period and make them unsafe. The manufacturing date is embossed on the side wall of the tyre, usually 4 digits, mine is showing 1306 which means the tyre was made in the 13th week of 2006. So those of you thinking to keep your car in mint conditions and not driving it much...(hint..hint "Hemi57")..better sell your tyres cheap to other high mileage 300C drivers every few years.
For those who are upgrading their tyres, just make sure the tyres aren't over 5 years old. Apparently there are people importing "old" tyres from other countries to sell them here.
