Just curious if you guys that are buying sport cup 2's are getting them pre-heat cycled or are you doing it yourself before you hit the track? Advantages/disadvantages? Thx
I've bought tires pre-heat cycled and I've done it myself with others. I get more tire life when I buy them done already (professionals in a controlled environment kinda thing). To me, it's worth the $15/tire to have someone else do it right.
Proper initial heat cycling of a competition compound tire is a must if you want to max the number of heat cycles a tire can offer. There are diminishing returns with less aggressive compounds, but they're still there. The Cup 2 (in my opinion) can benefit from break-in heat cycling. I don't think there's a magic or uniform # though. As with anything of this nature, YMMV. Bottom line, heat cycling a performance tire is always a good idea to maximize longevity.
As for paying the $15/tire, that depends on your setup. I will pay to heat cycle a tire for the GT350 because I do not have multiple sets of wheels / tires at the track for the car. I don't pay to pre-cycle tires for my race car because I have 4 sets of wheels and can plan for a break-in and immediate rotation process at the track.
Roughly speaking, you can get new tires up to their prime temperature range within 15 minutes (+ / -), immediately come off the track, and then let the tires cool down for at least 24 hours. You do not want to run a new tire much longer than 15 minutes if you're trying to break them in with longevity in mind, and you want them to cool down in relatively "warm" ambient temps (i.e., avoid temperature shocks).
Simple answer to your question: I decided to pay for the seller to heat cycle a set of Cup 2s I just bought.
