Never done a colder track day before and this is my first set of Prielli TDs. Going to be around 50 degrees F in the morning with the high looking like 70-71... how should I prepare for the earlier sessions?

(I'm running tire warmers)

Thanks for your help,

I have tried for months to get low temp information out of Pirelli. Please post your temps and pressures and results. I just had a front tire slide at 60 mph on cold slightly damp surface at 60 degrees. I am not surprised that no one has responded to your post. Most say use a street tire. IMHO that tells me no one is pushing tires in the cold and Pirelli just does not want to commit to any statements regarding DOT tires. Look at Metzler 77 race tire. Some data is out there on the 77 but only vague info on Pirelli track tires. I am in the same boat: HELP!

So how did it go? I’m sure some of us could learn some from your experience.

Alrighty,

NCBike, IIRC morning temps were as expected, 53ish. I ended up skipping the first session and leaving the tires on warmers for well over an hour. (Single temp 180 Degree warmers) I believe I was running 29/26 F/R off the warmers and zipping up my suit to go out after third (Final) call. I didn't have an exact temp for the tires but they did very well. I stayed off my normal pace until the session before and all sessions after lunch. I'm not a A group rider so I definitely believe the tires could've took some more abuse, I just rather would play it on the safe side. I don't remember feeling the need to adjust pressures throughout the day.

If you're really interested in how I rode the tires I have two videos on my YouTube channel, links below: (Unimpressive, I know)
Also, I had installed a new throttle tube that morning. Waayyy too many variables.. I know..

Note: in the first video I'm actually pushing a little and messing around with a friend, in the second video, I'm just following, so not pushing as hard IMO



(Oh, that's really nice, I can view the videos on this website)
[Hope this helps someone]

That’s great. I guess you’re happy with the TD’s then. What tire were you using before?

PS, I cracked up at the Beeeeeeeeep! when Matt got stuffed. :)

So under heavy breaking you had no slips or slides of the front? (Heavy being your strongest or most rapid squeeze of the handle) Did rear ever move out on edge grip? Was it smooth or sudden?
