Question in Tires

I'm currently running Pirelli DC3s. My pace is top of I. I was running 1:20:79 at Putnam this weekend and improving with each day out there. This was day 3 and 4 on my tires and they still had good tread.

The tires are starting to slip out on me more an more coming out of the turns. I'm aggressive on the throttle, but pretty smooth too I think.

What would be a good tire to go to next and why? I'm pretty much riding just track now. Do I need to start looking into a tire warmers also?

if your just doing track now. swap to slicks

SC Pro is the next step, your pace is getting there. DOTs or if you move up to the SCs, you can do DOTs or Slicks either way.

20s are nice at Putnam, you are getting close to the promised land, my child.

I like the idea of the SC Pros. That is what I was thinking. Should I be running warmers with them? My understanding is that warmers give you some better wear and traction first lap. Just don't know about the investment and hassle for warmers.

Thanks. Jim Cromwell was towing me around helping me cut my times down. We would do well for the first 3 laps of each session then we would hit traffic which was slowing my times down. We were especially working on T1 and T2 which is a whole different animal with speed (more fun). Hopefully you can help me shave some time in October.

Warmers help with tire longevity and cold tear. Really doesn't help that much with the first lap on trackdays as much as it does with the first lap in a race.

What he said^
Since I've started using warmers, my tires have lasted longer even as I get faster. They've helped regardless of tire, Pilot Powers and Pilot Race, all last longer with the warmers.

One thing I will say is (and some people disagree with doing this on the first lap but f them) I like using warmers during trackdays so i can go full speed on the first lap. The reason being is if you wait for your tires to come up to temp for 1.5 laps per session. You are wasting your money. You are missing out on 1.5 laps X 7 sessions. that equal 1 whole session you are just putting around ot getting the full benifet of wicking it up.

I had the same problem with PP 2ct's. They started sliding out real bad after 1 and a half trackdays. This is why I will not use a dual compound tire on the track. I switched to supercorsa pro's and love them. I get about 3 trackdays out of them, but they still don't slide out until the sides are almost completely worn out. I run warmers to save them from coldtear and to get the most life out of them. I just recently tried a set of Dunlop Qualifiers for an endurance day and have now gotten 3 trackdays out of them and have probably one left. While they aren't as good as the SCpro's, I am very impressed with them and will use them again in the future. After my pilot power 2ct experience, I will not run Michelins again. Pirelli and Dunlop provide a great tire.

<----These are the tires you want. They are WAY better the the SC pros. Not to say the SC pros arent good tires, but the new Diablos will last you way longer and stick even better. And in terms of tire warmers....what G2G said. They just make your investment last longer. Welcome to the club my friend, the faster you get, the more expensive it gets.

edit: and if you want to try a set, talk to Grouch. He bought a crapload of SC pro take-offs earlier this season that he won't use up this year. He may still be selling a few sets.

You must be running the wrong pressures. The 2ct is the hottest front tire out. Look in the pits of any club race and the one using Michellins are running the 2ct's nothing else

+1 on that I run mainly race weekends and I will go through 2 rears(pr5) to 1 front (prc) and never have a problem with the front going away on me

29-31 pounds in the front and 22 pounds in the rear.

Another thing I noticed from some riders around me at putnam last weekend was letting air out of thier tires after doing a few sessions..after you set you pressures first thing in the morning NEVER let air out throught the day. most trackday riders and racers dont have the knowledge or equipment to make adjustments like that through out the day. The tire manufactures give a cold pressure range knowing that will build through out the day

+1 on all that was said about the benefits of tire warmers with race DOT tires. I destroyed a set of brand new D209s in 1 1/2 days at autobahn due to cold tearing. I've never had the problem until I started running at advanced pace. I used tire warmers on a new set of PR2/PR5 power races for 3 days and the tire wear was even and the cold tearing has disappeared.

I went from a PR4/PR1 michelin combo and switched to a pirelli super corsa pro sc2 set dropped a second and a half my first session out. I don't think that was necessarily due to the tire as it was my first session after not running the track for a month so I had probably just forgotten my slow habits, but either way, really like the tires and they wear excellently.

Fire up some DOT race tires, get a set of warmers, and get a generator. If you don't have the cash now, put it on the christmas list. I know a lot of people are running the summomoto warmers and you can get those for $180 shipped off ebay. I've been nothing but happy with mine and they seem about 300 times better than tire sox for the same price.

What equipment? Looking at how a tire is wearing is all you really need or care about. If it's wearing well, you're set. If it's cold tearing, lower your tire pressure. If it's hot tearing, raise the pressure. Having the wrong tire pressure will destroy a tire much quicker then would occur by not running warmers.

Though warmers are the way to go. Find the correct pressure and maintain it.

I guess you always ride at a climate controlled track where the ambient air and track temperatures never change. That must be nice.

2ct's are all I have run at 5 different tracks and they have been great for me.

I never change my pressures throughout the day. The only time I do is if I am having tire problems or it is at lunch time when the tires and rimes are totally cooled off. The rule i have been taught is set them and forget them. You will do my damage than good trying to mess with hot pressures.

My issue with his post was the "NEVER" part. If the tire is cold tearing or getting greasy, you shouldn't be scared to play with the pressures.

I totally disagree on the hot pressure issue. IMO, setting hot pressures is the most reliable way to get good grip/life from a tire. I start with a decent idea what the cold pressure should be, then run the warmers for an hour till the center of the rear rim reached 100F (a $40 IR temp guagefrom Sears is good for this). Then I adjust pressures to Pirelli's suggested hot pressures. I have yet to lose a tire to cold tear using this method.

Not to complicate the situation but not all manufacturers recomend setting the pressure hot like Pirelli does. Either way Grouch is right, with a little research on the tires your running you should have no problem playing with the pressures.

FYI, I didn't have a problem with the front sliding, but the rear. By noon on the second track day with the 2ct's, I was sliding out at almost every turn. So bad that I came in early and had a guy ask me if I was smoking the tire on purpose, and of course I wasn't. I urge people to try the Qualifiers over the PP's. They have totally blown away my expectations.
