Tire warmers worth it?

Discussion in 'Track Time' started by Bellevuef4i, Sep 20, 2012.

  1. I'm newish to track days but run in the faster part of the 200 level. I'm still on street tires (q2s) and I know you can just do a couple warm up laps every session, but I feel like that's wasting a lot of my track day. And in the morning sessions the tires just aren't getting as hot. I can get Tire warmers for 160, and a generator for 80 (craigslist). Should I make the plunge so I can rail right from the start of every session or is it not worth it? Anyone else who's been in this situation?
  2. I wouldn't worry about warmers on street tires. Do a couple hard turns and you're good to go half way through your out lap. If you're tires are coming on the track cool any time of day you would just get them hot in the pits to have them cool off on track.

  3. I wouldn't bother with Q2's. They will be warm enough by the time you have one lap in.

    they may not need it.

    but a wise man told me that sometimes the little extra bit of confidence IS worth it.

    you may not need them, but really its your $$

    if you think it will make you feel better, so be it.
  5. If you don't buy them, post a link to the items, I could use some that inexpensive for my track bike!
  6. Adding to that, don't buy a generator for $80. Do us all a favor in the pits and don't get something super obnoxious

    If you're waiting 2 laps to feel confident on your tires, and you're at PIR running 1:20's in 18 minute sessions, you're getting about 14 laps total (13.82 ish for an 18 minute session, two for switch in/out), 2 of which you're spending worried about tire warmth. That's roughly 14% of every session. Cheap tire warmers run $150 or so, delivered to your door. Track days at PIR run $150 or so on average. 14% of an average track day is spent worrying about cold tires... so that's $21 worth of track time roughly.

    In 7 PIR track days your tire warmers will have paid for themselves in additional safe/full speed track time.

    Go to a track like ORP, where 2:00 lap times are a safe average to go from, and you spend 1.5 laps warming up, and there are 9 laps per session... you're seeing 16% or so at ORP. Average ORP day being $180 or so... that's $28.80 per track day at ORP.

    In 5 ORP track days your tire warmers will have paid for themselves in additional safe/full speed track time.

    Added bonuses include less likely of sliding around (and possibly crashing) on cold tires, less tire heat cycles so prolonged life, and more likely for a giant erection sooner due to being able to hit turn 1 like it owes you money right really there isn't a reason not to buy them if you're going to be into track days for even a year or two.

  9. If you are waiting for two laps for Q2's to warm up you are wasting about 1 1/2 laps.

    Like a lot of motorcycle purchases, I find warmers bring me peace of mind...not that I take it for granted. It will also extend the life of your tires, heat cycles kill the rubbers lifespan.
  11. The best part about Tire warmers isn't the warmup, it's the prevention of heat cycles, which kills tires. I have never ran them, been racing and doing track days since about the end of 94.
  12. Isn't the top of B class at pir about a 1:15?
  13. 1:15's is moving pretty good. Track record for a 600 is 1:07.1

    If you'll 'feel' more confident with warmers then i'd buy them.

    Considering racers winning events at PIR are posting about doing 1:12's... I'd be surprised if a 1:15 was the fastest lap of those legitimately in the B Group.

    As for Q2's taking two laps to warm up... I agree they take much less. I bet it's as much about the rider taking the time to warm up for two laps as the tires themselves.
  16. Yeah, 1:12's will put you up front for senior 600ss races, and 1:19's will graduate you from novice to expert on a 600. I have never done a track day there so I have no idea what kinda times people run on track days.
  17. Last time I was there, I wasn't the fastest B guy, all I could muster was mostly 17's with the occasional 16 lap. I figured it was due to the new layout and not having been there in 10 or 12 years. I was personally about where I left off when I stopped racing.

    Good info. Thanks guys.

    I run Michelin PPs and have my knee down 1/2 way though the out lap. I also do not notice any heat cycling with these, even after 5 track days with multiple cycles, I can do cold stoppies in the wet on the street. If you're running race tires, warmers are worth it. JMO
