I have a set of four Goodyear GT original factory tyres in good condition that belong to my 79 car, they are 255/60-15 RWL, I am giving them away to anyone who wants a set of original tyres, you pay freight, they are on the sunshine coast.
These tyres are in good condition and look great on the car but are NOT for highway use, the rubber is hard and they are dangerous to drive on, they just dont hold the road very well, the tread is about 50% and the only reason you would want these tyres is for originality for a Bloomington award or similar. Goodyear stopped making these tyres around 1981 so they are pretty hard to come by these days.
PM me if you want photos or more information.
Thanks, Dennis.
