I am not sure when your tire was shredding on you, but a while back there was a recall on the Front 2CT's.

2CT's are good tires, more street oriented. They'll be plenty for your track needs.. drop the pressures and take your first lap easy to get a feel.

I was running Pirelli DCIII's (which I think are comparable to 2CT's) during the track day in my avatar, which I think was my 2nd or 3rd TD and never had an issue.. good grip for a street/track tire. I ran 28/30 cold and no warmers..

I run a lil less pressure in my front to get a lil bigger contact patch.. fwiw

It will depend on rider feel and preference, but USUALLY we run higher pressures in the front. Front tires are made to flex easier, so if you run too low of pressure, you run the risk of over deflecting the tire. Especially advanced rider, using a lot of trail braking. We always run lower pressures in the rear, because the rear tire us usually made slightly stiffer. It is made that way because typically the rear tire takes most of the abuse during racing or trackdays. So we run lower pressures to maximize contact patch and feel. The best way to help a rear tire last longer, is to keep it from spinning. The more it spins and moves around, the faster it wears.

Guess I have it backwards! Always nice to learn.

All of ya'll that run lower pressure in the front tire.........why? SCRC John always recommends the other way around.

Some people may suggest otherwise, but I would stay away from using warmers on street rubber, at least during the afternoon when it's a little warmer out. I tried using warmers one trackday on a BT002RS set. Tires got a little slick in the afternoon, so I took the warmers off and everything went back to normal. John could probably explain in a little more detail. I think it has something to do with the extra oils in street tires, as opposed to actual race rubber. Then again it could have been a little too much pressue in the tires at track temp.

If I had to guess, as the ambient went up, your "Off the track" temps & pressures went up. If you would have reset your off track pressures to the appropriate numbers, you would have been fine.

Remember guys most warmers are thermostat driven, thus they should not be getting over 170-175 deg F. At that temp, the tires are fine, they are not too hot, nor can you "melt" a tire on a properly functioning set of warmers. Now if your thermostat fails or you have a short in you warmers, thus causing a "hot spot", then all bets are off.

I'm pretty sure I was adjusting the pressure while they were on the warmers. Of course that trackday was a good while ago, sometime early last year so I may not remember too well. I'm usually paranoid when it comes to tire pressure.

I like to think the warmers were good that day because that was the day I rented a set from YOU.

I'm sure the warmers were good too, then

What is important for everyone to remember is, to set your pressures when you come off the track. Warmers are used to set pressures closer to the actual off track pressures, and to use as a tool to limit the variables when it comes to setting tire pressures. Warmers pressures are not the end-all-be-all. Ultimately off the track pressures are what counts.

The tires held up great! Overall for the first time using the 2CT's I was impressed. They handled great all day! Thanks everyone for the info and advice.
