Cold Track, Green Track, Tire Warmers and Cold Tires...

So I have heard of tracks, or certain days, that the track "never comes in". For example on Saturday, TWS (Texas World Speedway) seemed slick to me. I keep hearing people say, awe, cold tires...you gotta let your tires heat up.

Well, I have warmers, and ran a lap before I got on it, and teh track still seemed weird. No matter how hard I rode, it just didnt feel right and my lap times were disappointing.

To me, it seemed like ALOT more than "cold tires." The track was just slick to me, no matter what.

Will someone explain "green tracks." Or "tracks that never come in?"

And, is it true, that sometimes, no matter how warm your tires get, the track just isn't good??

Yea I heard people saying they were sliding all over the place, it felt almost normal to me, I did ride a little more conservative than normal but not much. It was a good day of working on riding smooth.

It would suck to ride track up north where its cold 8 months out of the year.

There's a huge combination of factors that can cause this. Weather is the biggest one, and prior weather is, too, (e.g. if it rained the prior week and washed rubber from the track or put silt, dirt, etc. on the racing surface). Prior events can contribute as well, such as car or kart events that might alter or contaminate the lines that bikes use.

Sometimes a track feels green, though, and it's not the track - it's your or your bike. Say that the weather is 10 degrees cooler today than yesterday. The track might feel slippery and green, but it might really be your settings that aren't happy. Oil moves through orifices a little slower now that it's cooler, so the suspension might not be as balanced and it might make the track feel green.

I could go on and on, but I think you get the gist of it.

sometimes there will be dust on the track

sometimes the track itself is cold

sometimes the rubber usually left on the track from other cars gets washed off

its nice running at MSRH since the cars that run inbetween the bike sessions help clean off, dry, and lay down some fresh rubber on the track for the bikes, you need the sun to warm the track up though.

And I assume only experience will help me determine whether it is the track, or my bike, or me.

Cold track/green track: the track surface is not yet warm. Its not enough for just your tires to be warm for max traction, the surface temp of the track also needs to be high. Thats why most people talk about the track "coming on" in the afternoon. The track heats up as the sun beats on it making it easier to keep heat in the tires as you ride (the track isn't sapping the heat) AND the surface becomes slightly more pliant too (hence the ripples in the braking zones from cars).

It is not always about track temperature. A cold track does not always equal lack of grip.

some "old racer dude" told me one time about tires and tire pressures. CDill ask if you should have adjusted your tire pressure. Maybe lower pressures would heat up to the right temp vs higher pressure (normal psi) me dont know

OK...then riddle me this....

Why was everyone, from what I heard, several seconds off their normal paces at TWS (Texas World Speedway) on Saturday?

I don't have a cool t-shirt with my board name on it.

I saw you during the rider's meeting, but couldn't find you in the paddock afterwards

It could be as simple as someone saying they thought the track was green. Word gets around the paddock quick, and people tend to back off just a tad. Was anything mentioned at the rider's meeting?

There were constant PA announcements for people to let thier tires warm up. And maybe some additional announcements that I didnt hear.

All tracks and tires act differently under different tempatures. With that being said, it was fairly cool Saturday for a track like TWS (Texas World Speedway).

I never reduced my pace all weekend even when it sprinkled. With it cold out on Saturday, I did give myself about 1.5 laps to be sure the tires heated up well.

BTW, I have never had any traction issues ever at TWS (Texas World Speedway). It still suprises me how much traction it has even in the rain. Eagles Canyon on the other hand.....
