AT 24 PSI my BFGs hooked worse than my radials, 1.9 60 ft, at 20 PSI better but I still had a lot of wheel spin with a best 60 ft in the 1.8s, at 17.5 PSI they hooked hard, I would do a hard burn out, no power braking, and I pulled 1.6s 60 ft all day long. With a line lock should be able to get the short time into the 1.5s. At 17.5 the tires look pretty low, but they seemed to work the best. All of these pressures were with relatively cool tires.
