I run the 14.5/32 soft sidewall and don't run tubes. With a 3200lbs 9.40-50 car I run anywhere from 11-12 pounds depending on the track. M/T tires don't like to wrinkle excessively and like more air pressure. The more air pressure you can run the more stable to car will be on the top end.




also not enough air will kill 60ft. and reaction times!
I could never run 7-9 #, car to unstable at the start, and wonder all over the place on the top end,
we run 12.5 in the coronet with hoosiers tubless, but we did have MT and ran the same pressure!
