I have two more events this year. Possibly more depending on how the fall goes.
Two weeks ago was my first event of the year where temps dropped below 80 and of course the sun is setting earlier and earlier.
We normally get the first car about by 730/745 and here in Ohio the sun is setting at 730 now. Our lot is a good solid surface, however it absolutely does NOT hold any heat.
My first two runs were solid, but by run three the sun was fully behind the trees and the pavement temps were dropping quickly. I couldn't keep temp in the tires. We get about 5-8 minutes between runs so things are cooling off quickly plus we are typically getting breezy evenings right now.
I ran F 41 and R37 to start and adjusted down/out after the first run for f40/R39, but after run three I was fully bottomed out temp wise and wasn't prepared for that with spare air. I do have an air tank, and IR temp probe that I can take.
Our runs are typically around 30-40 seconds.
I'm running 615k+ tires - these apparently like some heat because cold they basically drive like they are made from solid plastic.
The next event is in two days and the high for the day is predicted to be about 60F.
All of that to ask...
How are you keeping heat in your tires? Or even building more heat during runs?
I was planning to start around 38~ all around to build up some heat and see what grip is like. But even still the time between runs might make it moot.
