DOT race vs street perfomance 4 track dayz - June 23, 2007, 03:34 PM

peeps,
how much of a traction difference are DOT race tires than Ultra High performaces street tires.

I currently run bridgestone BT-014 (OEM honday CBR1000RR) but usually run dunlop DOT race tires on track days. I was a little nervous about really pushing the street tires at VIR North yesterday.

That said there was this little kid about 10 years old on a two stroke that had amazing cornerspeed. don't know who he was but keep an ear out!

DOT race tires have exactly 6.66% more grip than a good high-po street tire.*

*This figure may vary by 10% in either direction due to differences among brands as well as models. In your case, the 002 Bridgestones will provide you a noticeable difference, but won't last as long. In addition, it's harder to pinpoint the limit of a street tire. Generally, a race tire will give way more progressively; whereas a street tire might toss you on your ars.

Look at the money. If you can afford it, buy the best. If it's something you can't justify, then the money you save should be balanced by an equal serving of caution in the corners.

You're about to hear a dozen more opinions on this subjective question, but I tried to give you the straight poop.

My poop is a little more crooked. I ran M1's for my first couple track days two years ago and decided to get the Racetechs because of the buy one get one free thing they had last season.

Could I have just saved the $ and run the M1s yep. Are the Racetechs better, yep. The tires are better, better feedback, more grip, more stable.

I would spin up at will exiting most corners with the M1's with the Racetechs it is much less frequent, much more throttle and less than ideal track conditions are necessary (too hot, cold, or wet)

If you are spinning up alot, sliding or are just not comfortable with the street/track day tires give the next level of tire a shot.

I use to think BT-012SS's would suffice for double duty. For a novice rider they would but when things start to get pushed then the limitations of a 'street' tire began to show. I will only run SuperCorsa Pro's now at the track because; 1. If gotten quite use to their feedback and how they work and 2. You can push a street tire and maybe you can go fast on it but the confidence that a DOT race tire has is not there.

+1, I used to run powers, now I run supercorsa pro front and a dragon slick rear, I'm gonna try the race 'stones next, but I totally agree, the ability to get on the tires hard and not have to worry about them is a huge confidence builder...[edited]

Tire warmers don't make a damn difference. Take a look at lap times for the LW superbike race at Summit at the end of May. My first lap was faster than everybody's except for Art Diaz. And my second last was my fastest lap ever. No warmers for me, everybody else has them.

Plus tires have no rubber left by the time they might reach a point where heat cycles are an issue. I've run a front for an entire season plus trackdays and that's on an SV. Big bikes can easily finish off a set of tires in a weekend.

Isnt that indicitive of just using the better tires to band-aid some other sort of problem?

Thats the way it always was with my students in cars... throw gumball rubber at the car and it bails them out of so much crap, that when it hits the fan they crash because they have no idea how to handle a slide.

I can understand that.

In my case I went from a tire that would step out and upset the bike as a whole (BT012) to a tire that would slide but keep the bike composed (SC2). The way the tire reacts with the set up of the bike is an important part of the package. Yes, the SC2 has the grip needed to keep the bike planted but a proper race tire should also let you know that you are pushing without the fear of letting go.

The big twin can kill a tire in a hurry, having it slid without loss of control is/was a huge bonus.

I guess my rub was with the statement that "xx tires caused me to crash". Just about any time you fall off, there's a problem between the handlebars and the seat regardless of equipment. On street tires last weekend I almost high-sided in the 1st session, pushed the front a few times, and spun up the rear on exit a few times. I never felt that I didnt have control of the bike, or that it wasnt caused by something I did to upset the bike.

I dont see any need to move up to a track or race tire until I think street tires are holding me back, but diff'rent strokes.

This type of shredding can be remedied. Try backing two clicks off your rear compression. If that doesn't work, I would add a pound of air. Your tire's doing all the work and coming apart. Actually, it's not that bad, but it's a problem I've fixed before. You'll get more rear grip AND more tire life. No trade-off.

never had an issue running M1s or Mich. Pilot Powers on the track. Wouldn't race with them, but track days they work great and last a bit longer imo. I'd suggest for ease and exspence to stay with the DOT approved Track & road tires i.e. Pilot Powers, Diablo Corsa IIIs etc..

I just stepped up to the Corsa IIIs on my R6, should be interesting to see how they compare to my Pilot Powers...

I am having this same debate about which tire to run. I am going to run the BT 014. Is this a good idea or should I just go with the pilot powers?

Most street tyres will be good for a track day. They also make track day tyres in general.
