My 84 Boxer Still has its original Tires....I am sure for the undercoat overspray from factory had hit the inside of the tire and wheel and appears original...20 year olds tires and they still ride and look new..However with 2000 orig miles on car its time to replace them...I plan on racking up some serious miles this summer. Any one know if Michelin is still Making this tire and who has fresh tires in the USA. It is the metric TRX . Standard equiptment on the 512 Berlinetta Boxer. Thanks Michael.
