We just started running rubber tires last year and some people used them, some didn't. I tried them out and liked them. Without them, it would take 2 or 3 laps to get the tires up to temp and I was losing between 3 tenths to a second per lap. If I left the warmers on until just before the race, the tires would bark and scrub a lot of speed, so I turned them off about five minutes before the race and left them on the tire to maintain the heat. That system seemed to work very well for me. Give them a try and see what works best for you. I'm using the MuchMore can warmers without the temp control.
