[Fot] Toyo R888 - tyre pressures?

[D V]

Agree. I ran 28 cold on Saturday and shaved almost 2 seconds from my times in the spring when I was running 25 lbs.

I could definitely tell a difference especially in the carousel where I felt I could carry a higher speed.

I tried a couple of different pressures this weekend at MSR - Houston . My best times were with a cold tire pressure of 28, hot was about five degrees higher.

In other news, I broken an axle on turn 11 and got to watch my right rear tire make it all the way to turn 13! Spitfire breaking and axle? Same old story, new Storyteller.

That's consistent with what I've found with the R888 pressures.

I am faster with R888s but that's likely due to going from 60s to 50s.

I believe the website says 32-38 hot with temps 160-220.

Be curious to hear what others say. I think my car is faster on the Hoosiers.

Wish I was going to COTA with you guys in Nov.

What cold tyre pressures are you using for the R888s?

The car is a '62 Spitfire - 1425 Lbs with 5.5x13 wheels  The tyres have been shaved and heat cycled.

I have heard that they work best hot in the low 40 psi range and you should start off at 33-35 psi.

Looking for others thoughts and experiences.

Thanks
