Tire Pressure In My Mt Drag Radials

[steve davis]

With My Set Up What Air Pressure Should I Start At In This Hot Weather

 

[pacecarta]

17-18 psi

MT site recommends min 16 psi for cars over 3000lbs

ive tried 15 and they flap after launch like they were flat
tried 16 and they hook ok
at 17 ive hooked and actually spun the tire on the rim
at 18 little easier to break loose
forget 20 too little tire surface meets the pavement

for drive home pump em up to about 24

on 255/50-16 theyve done 1.50s
in the heat i did consecutive 1.55s
