I just bought 3 used Toyo R-888s from a 914 world member here. it would be great to have a 4th tire. we use these as practice tires then run timed laps on Goodyear canteleiver slicks.
a used tire with moderate amout of meat left would be fine but not hard and old.

buy or trade. I have tons of 914 parts to wheel and deal. bring your car to my shop and we'll do a data logging session, wide band O2, air fuel ratio, put it up on the lift ...
