Assuming your still running Pirelli SC's I run front 31 and rear 28 and both of those are HOT. If you have swapped out to a different tire manufacture the numbers are not valid and you need to find someone running that brand/model for numbers.

Yes like that. It's not an exact science as it depends on so many factors such as your riding style and the track surface, ambient temps etc. Queuing for a long time will cool them down a bit but it's not really a heat cycle as they'll still be hot inside. If I'm hanging around off the warmers I just try to go easy for the first few corners and warm them up a bit again by accelerating and braking in a straight line.

So what kind/type of warmers do you guys recommend. There's a lot out there when I look and I dont know if dual temp are needed? Pretty sure digital is needed to set the exact temps right?

Having a low setting is nice during long breaks like through lunch. I usually just use the high and low settings on my chicken hawk pole positions.

Gotcha. I think someone here mentioned that they do their first run, measure the temp of the tires, and then set their warmers to that setting.

I'll echo some of the posts... Check first thing when they're up to temp on the warmers, and then it's the first thing I check when I pull in. I try to ride reasonably hard after the checker to keep the heat in the tires. Also at the end of last session, put on the warmers on right away, even if they're off to prevent them from going cold too fast.

Maslov seems to have it right.

Setting cold temps is really only going to give you a rough idea, and not something I would rely on. Pressures go up a lot or a little depending on many variables: ambient temp, track temp, circuit characteristics, riding style/pace, weight of bike, duration of session, etc. The most reliable way to account for all of that is not to conclude that "pressures go up 4 psi," but rather to check your temps when you come in -- as Maslov suggests. Second best is to check them when they have been in the warmers for about 45 minutes.

I second Maslov's suggestion to wrap up the tires in warmers as soon as you come in. This makes the range of the heat cycle smaller and also makes the cycle less abrupt. All good for tire life and consistency. For the truly concerned, it's a good idea to throw the warmers on unplugged after the last session/race of the day -- that will give the heat cycle a much slower and gentler transition to amibent temperature.

One final note: if your tires are greasy, I would NOT add pressure without verifying that the pressure is too high. Your tires may feel "greasy" because they are actually over-inflated. Adding more pressure will give you even less grip. In my experience, the answer is usually to go down in pressure, or try a harder compound, or be happy you've reached the limits of your setup/tires/conditions and enjoy.

Back in the day I would always go of off the Goodyear reps cold pressure recommendation. And then check my pressure gain coming off the track. If I was getting too much gain I would go up a pound or two on pressure to cut down on carcass flex and reduce heat.
No one used nitrogen back then, now I use nitrogen on my street bikes, race cars, even go karts. It stays much more constant and predictable on gain, due to low moisture content.

So guys, i narrowed my selection down to two choices;

A digital warmer with a decent price to get exact temperatures.

Or a dual temp,

Wondering what your thoughts are. Are the digital warmers really worth the extra $$$? I'm def willing to pay the extra money if it will make my tires last longer and feel better.
