I just bought 2 mickey thompson sportsman "I"'s the n50-15's for my 71' big block that makes 600ft lbs from below 2000 up to 6000 and I was wondering what the best tire pressure would be both for street so that I get best traction with acceptable handling and for the track so i get traction. Thanks

i run the sportsman pro's on the street. little wear and i run 16 on the street with no handling problems at all. i dont know how low you can go with your tires though.
