Tire pressure for stock 19" in light rain
Quick question - what's the recommended tire pressure for HPDE for stock 19" PS2s with possibility of light rain? I did search but all info was old - people probably have more experience tracking these cars by now.
Thanks! |

Last year at Calabogie,I ran normal street pressures of 33f35r on The 19" PS2's with no problems till I switched to normal track setup when the track dried.

Did two days with about 1.5 hours dry and 2 hours slightly wet plus 1.5 hours of wet skidpad on 39psi cold all around. With -1.4 front and -1.45 rear I had very even tire wear on the rear and a bit more outside wear on the fronts, but overall I was happy was the set up.
Behavior in the rain was interesting, though - I could progressively oversteer with either lifting of or giving more throttle in the turn, while balancing the car with the throttle or slightly accelerating in turns caused understeer. My instructor did not let me do any throttle oversteer (he put a car in a wall a week prior by doing just that in the rain), so I ended up understeering most of the time. I guess it was a driver problem - I will try higher entry speeds with less throttle in the first 2/3 of a turn. |
