You can't really make a blanket statement like that. Last year I ran four different race tire types. Each of them had different feedback at a whole range of different paces. NONE of them gave this "...whisper quietly right before they high side ya to the moon." feeling. They were all predictable and smooth. If I were to generalise, I'd say street tires give less feedback and are more unpredictable than race tires.
LOL... yep. Maybe I'm not fast enough to know, and my bike is too loud to hear the tires. Oh I know, I didn't try Michelin, they must be the ones that suddenly high-side. Seriously, I think they are. haha...

"The Sticky Stuff
Everyone wants to have the stickiest rubber they can afford but it isn’t sticky until they can put the big load on the tires. Most riders would do better and learn heaps more about traction with something lesser than full race, factory rider developed tires. Why? They don’t have to put the big loads on the tires to start to experience the bands of traction as listed above.
Look at it this way. If you are using the tire at the bottom end of where it was developed by pro riders would it actually save you if you got brave for a moment? The answer is no. Pushing the loads on the tires up for a moment when the rest of the lap was at your normal pace will not give the tire enough time to warm up to the level you momentarily demand from it to handle the situation.
In other words, your potential and that of the tires have to come up together for you to take advantage of what the tire has to offer. To a large degree, the security of the stickiest rubber is false. Until you arrive at some consistency in your levels of speed and lean angle and throttle control and the other technical parts of riding it is no more then blind faith"

From keith code and a better way of saying what i was trying to. When you ride around on a race tire slowly you may get predictable grip, but you're not working the tire hard enough to get proper feedback. Where as a TD or street tire will start to slide at a lower pace, it can actually be more beneficial to a slower rider for them to experience the edge of traction.
I can find the edge of traction on a TD tire, i havent been able to find the limit of grip out of a front race tire. I've always felt like i'm not going fast enough to know if i'm near the limit or not, it just sticks.
It depends on what you're after I guess. If you want to learn what it feels like to slide, then Keith is right.
As for getting tires into their proper traction zone, DOT race tires, in my experience, tend to behave like street tires. Probably because they are street tires. You don't need to run warmers with them, just take it easy for a few laps to get some heat into them. Slicks (I've tried Pirelli SBK (not the pro) and Bridgestone so far) on the other hand don't like being cold. I was helping a friend in the green group one day on Pierlli SBK slicks. The last lap I turned it up to see how the tires were and I immediately started sliding them around and couldn't go out in red group without pitting and getting the warmers back on. I did similar tests with Bridgestone R10s, Pirelli Diablo SCs and Dunlop D211GPAs, all of which were fine at colder tire temperatures if you gradually bring up the pace.

The tires youre going to buy for trackdays are not going to be full factory race tires! That's like saying don't put Formula 1 race car tires on your corvette. Of course they aren't going to work well. But if you're a new trackday rider reading this - Any DOT from 2013 will be such an awesome tire that you would have to be pretty crazy to crash on them. Pirelli supercorsa DOTs are street legal, warm up fast and when used with warmers will be awesome from corner 1.
It really shouldn't be tough to figure this out. The big tire names will all work and they will tell you if the tires will be track suitable. Or listen to the guys at the track...

So then how can you tell people that "race tires are unpredictable" and "will high side you to the moon"?
Uhh the tires you can buy are the spec tires for the AMA and CSBK.
Wish I could find a quad facepalm pic

Because your not pushing the tire to an Alex Welsh level so they don't work, duhh. They also have nothing to do with braking but everything to do with breaking.
The amount of faces that need palming are reaching epic proportions in this thread.
What do you mean? Supercorsas are used by full factory racers. Any one of us can call Orion and get the exact same tires they use in CSBK Pro 600.
No kidding! When I first saw this thread I was going to ignore it... but I couldn't. haha... It's the off-season, fun threads are rare.

FYI the D211GPA is a KR448/9 slick with tread.

Yeah I know, there is some crossover on compounds, and I'm not saying that all slicks (or DOTs for that matter) would behave that way. Just sharing my experience.
