Tire Pressures for Pilot Sport 4Ss
What are you folks running these at on road courses?
I was trying for no more than 38 hot/34 to start, but it feels like the lower I go the better the traction all around. I know the performance supplement says like 28 cold but that's specific to the 1LE, and I'm having a hard time convincing myself to go that low, and up at the 38+ range they feel like they're giving up grip too quick. Our format is HPDE runs in the morning, and then one run laps in the afternoon for times, so it's a bit of a shift from morning to afternoon. |

I'm thinking of keeping the rears in the 34 range next time out and dropping the fronts down to 32-ish (hot). Rear feels pretty planted at 34, fronts still feel like they're scrambling for traction more and more as they get up in pressure. |

I was at pocono raceway this past weekend. Track temps were really hot. First i tried 31-32 cold and that netted me 39-40 hot. And i can tell you these tires dont grip to much at that pressure. It most likely was the heat, then i let them cool down for a while.... Aired down to 29 cold...... Came up to 34 hot and that was the sweet spot for me. Mind you im running 305/19 f... 325/19 r....

After playing around this weekend, I feel like my best grip was at about 32psi front, 34psi rear.
I'm regretting not trying to push a slightly wider tire up front than the stock 245s, as the front tires are just giving out way before me or the rest of the car. Although I may need to reconsider how i'm approaching corners. I think I need to force myself to get a little more throttle in to shift the weight back on the rear and not over load the fronts. |
