    That is a big IF! lol I get your point and I agree with it, I'm just saying for most of us, it'd be a waste of time and electricity because we'd lose all that heat. WSBK guys are likely faster in the wet than I would be in the dry, so yeah you're probably right that they can get them around 120 F. I know I can't get mine to that. When I've come in the pits after a wet race/session, took my glove off and put my hand on the tires they felt about the same as ambient temp, just slightly above ground temp. The only time I've used warmers on rains (and on low setting) was when I was under a big garage and I could keep my bike and warmers dry...and that was during a track day actually. I don't like to get them soaking wet so if there's no roof of some sort over the bike, I don't put them on. Certainly not hurting anything by using warmers on rains, so long as you watch the pressures and make sure they're where they need to be.

    Consider that WSBK, et al, prolly have team members whose sole job is tires and their management...not to mention that there gear - pressure gauges, IR, durometers, etc. - is likely calibrated within points of a percentage. We're talking professional racing with big bucks on the line.

    I think Mike nailed it...and/but if you know your gear is accurate, know how to utilize it and keep records to manage its use, you have the info to make your own decisions. That's a lot to do for a club-level rider, as if they didn't have enough to deal with single-handedly.

    I don't remember actual in use rain tire temps. But I'm going to hang with some Pirelli racing peeps from Milan in a couple weeks so I'll find out and report back.

    i've never used warmers on rains. they get hot enough on the track from riding. i'm chasing puddles to keep them cool.

    I've been at this since 2003. I've done a lot of rain racing in my day, and when i actually bothered with rain racing, i won a LOT of rain races. why wouldn't you want the tires as warm as you say they are getting on track "from riding".. right away? and you do understand you only need to chase puddles when there is a dry line forming, or the track is wet, but drying. What you are saying, is nearly the same as saying "i don't need to use warmers on my slick race tires, they will get warm enough on track"

    Yes folks.. i get it's one more thing to worry about. that many riders will warm em too hot and potentially blister the rains. That some won't go fast enough to get em warm enough to really work. BUT, if you are smart, dillegent with procedures, have quality multi temp warmers , there is no reason you shouldn't be running warmers on rains. My opinion.. i totally get why Mike and others will suggest to customers not to do it.

    PS: in the michelin tire catalogue , it discusses using warmers on the rains.
    › Maximum grip thanks to its new rubber and new rear tread.
    › A deeply-grooved tread for maximum water evacuation
    at high speed.
    › Temperature versatility.
    › If tyre warmers are used, it is essential not to exceed 60°C.


    again.. do you have to use warmers on rains? no. Will it benefit you to do so ? probably...

    Only since 2003, what a rookie

    Anyway 60c is 140f so not that much above the suggested warmer setting for the big P rains of 122f.
    And FYI I have never seen a set of Pirelli rains blister/chunk from being only on warmers

    Just don't think that although they were never used that 5 year old rains are ok. I bought some and it ended badly. After when I went to buy more I felt how soft a new rain tire is and realized mine was dried out badly.

    Proper storage is very important with all race spec tires, especially with rains.

    I used my decade old rains at the dragstrip...no slip AND keeps the competition wondering. :D

    All tires need to be stored in a cool dark place. And I've seen 2 year old Pirelli DOTs win a AMA pro race and 3 year old rains used at Miller WSBK.

    You should have seen the looks we got at Bonneville when we used rain rears and set records doin so!
