1970 914-6 race car with 15x7 wheels and hoosier 23x9.5x15 slicks 35 compound. Also goodyear 23x8.5x15 slicks 250 compound. Iam using the car for hillclimbs. On my Golf GT-3 car I used same pressure as autocross. Tire have to stick fairly fast. Also front and rear differance in pressures. Thanks Paul biggrin.gif
