Slicks vs DOT

I would like to ask some more stupid questions.


I am a trackday junkie with a GSXR 750(former race bike). It currently has pirelli diablo super corsa tires. I think I wanna try slicks just for the of it.
So, my questions are:
1. What brand?
2. What compound would give similar wear to what I'm using now?
3. With that compound would I see a noticeable difference in traction?
4. Would suspension changes be needed? (remember I'm not a racer and will never be)

I'm pretty happy with the bike as is but thought slicks would be an interesting experiment.
Thanks for any input you can give.

1. any brand could handle your ability, remember even a pro could not out ride these tires.
2. you have to know what compound you have on it now. It does come with different compound for different temp of the track. Cold track days should use soft or supersoft not medium soft.
3. not at your level
4. different size tires required different geometry set up. 190/60 or 190/70 and stock is only 190/50

I am not a racer only wanna be.

First off let me say, for trackday guys, slicks(any brand) are a not-so-good of an idea. Yea you can ride on them, but the extra cost will be wasted $$. plus the DOT's are more versitale. If it is damp or lighly raining, the DOT's still work, but the slicks are useless.
Lets not even get into the fact that "most" trackday riders, are not fast enough to load the tire carcass enough to sustain the proper heat in the tire. Even with tire warmers...the tire will actualy cool off on the track. Maybe not so much of a problem in August, but for the most part that is the case.
If your still interested in them, Bridgestone would be my first suggestion, for the cost, they are the best bang for the buck. Dunlop a close second, they cost more, but an awesome tire none-the-less.

1) any brand...see suggestions
2) You you got now?
3) I would say the super soft/soft set will give the most feedback
4) Susupension "tweaking" may be needed as the tire reacts differently

I'd suggest sticking with the DOTs, i only say that (from what i have heard and read from racing articles). If your just a track day guy, and not looking to do race times, then your better off saving the $$$ and going with the DOTs.

Again, i'm in no position to say that from personal skill level - just a suggestion based on reading and hearing.

ive been wanting to try them too, but after running a pair or supercrosas i didnt think traction could get much better. I cant even imagine what ohlins/penske suspensions must ride like:icon_smil

There is an EXCELLENT article on tires in the December 2006 issue of Sport Rider magazine. I am sure it will answer your questions. It has a lot of dimensional data, street and track results / comparisons.

I read that article.
A couple of problems I had with the test.
1) they used 2 different bikes for each brand. Michelins on a R1 & Dunlops on a ZX6R.
2) They put a Michelin rider on the Michelins & Trevitt(I think) on the Dunlops
3) They used tire warmers on the racetires before the street test? who does that? why use race tires on the street anyway

I can go on and on. In the end the test concludes nothing. They say each tire brand does some things good & some bad, but overall they were pretty equal....thanks for stating the obvious

Thanks for all the input I know some of you are way more knowledgeable than me. However i noticed that some of the input was preceded by saying things like a track day guys wont be able to heat the tires or aint fast enough to see any difference.
Nobody even asked how fast I am. Maybe I am fast as but choose not to race for other reasons.
OK I'm not fast but still... Ha ha ha

How do I determine the compound in the supercorsas I have now and should I stay with a similar compound in slicks or go softer? I am not trying to beat it to death, I just don't know.
Thanks again.

I was only assume that you are not that fast by asking these questions. But, IF you are as fast as a Pro racer, you would be giving us advice, right? I think that there are a SC1 or SC2 on the side of the tire stating the compound. If you ever goes below 2 minutes at TWS (Texas World Speedway) then go with Dot race other than that I would use Michelin 2ct or regular PP. Works great on street and track.

I thought all sv riders were supa fast? lol
I suggested slicks because you were on a sv. I really like the feel of the 250gp slicks.
In the case of this thread we are talking about a larger inline bike, in that I stick with my above post.

John

PS I have not forgot about your Dunlops

take offs can have worse traction than street tires........there's a reason the person that paid retail for them isn't still running them.

You don't have to defend yourself, I'd have been perfectly happy if you just said I was fast :icon_bigg

I rode them on a damp track the other day, not as bad as I expected. I'll talk to you about the next set one of these days.

Alot of friends of mine are trying the new pilot power 2ct's They are really a good tire lots of soft rubber on the sides and they stick really good. Should be a great tire at the track also. They are a dual compound tire I believe the centers are medium and the sides are soft compound. Try those for a good all around tire.

Now that the brand thing has been answered, all I am asking is:

1) How do I determine the compound of the supercorsas I have now?
2) What compound slicks will give similar wear, once I determine that?
3) If I use a slick with a compound that will wear the same as the supercorsas, 4 trackdays and a sprint race and still look ok, will I notice a difference in traction?
