Conti race tires..... Who

[mauro#749]

Anyone is racing with continental attack race tires?......
I got a 05 gsxr early this year and I got a grate deal with the Bostonmoto guys on a set of continental race tires they are soft, I don't have much experience with other tires, I did use bridgeston before but that was with a ducati ( trackdays only )..... What do u guys think about the conti?.. I feel that I constantly fighting with the bike, ........please some feedback .

Sounds like a bike setup issue to me. I would talk to Kates or Martire to make sure the bike setup is in the ballpark then talk with the BoMo guys for suggestions about the specifics of setting the bike up for the Contis.

i came off of pirellis when i switched, but all i really had to add was 2 rounds of preload and the bike handles great.

[burnham]

I just put a set on last week. I took two turns of compression damping out of both ends and the bike feels great. I also came off Pirellis, they feel really similar, just a little stiffer. Spend some time getting your bike set-up, it's normal for a bike to feel strange when you go to a taller/shorter/wider tire.

[scottieducati]

If you are coming off Pirellis the general rule is to soften the bike up via taking out pre-load and / or compression damping. The tire diameters are the same (e.g. no ride height changes) but the carcass is stiffer, so the suspension must become softer to compensate (this all assuming the bike is properly set up for Pirellis in the first place).

We have sag #'s and basic settings that are known to work, and a measurement at GMD is always strongly recommended. If you are not willing to do the set-up, you're going to be fighting the bike no matter what's on it... unless you hit some close #'s by guesswork and trial and error, which takes much longer, can be very confusing, and likely will cost more $ in the long run (crashing, poor tire wear, etc.)

The above goes for ALL brands of tires.

We just got CEO's bike dialed in (which should have been done a long time ago, partially my fault for being so busy) and he's right back to where he was last year lap-time wise... maybe he can chime in a bit.

Air pressure is critical as well...
...I believe HOT OFF TRACK pressure

SLICKS 29 front and 26 rear
DOTs are 30 front and 28 rear

I moved from pirellis to conti race attack slicks and I've had no issues at all. I really like the tires. My lap times dropped 2 1/2 seconds on them from the fall when I was on the pirellis.

[scottieducati]

Thanks Dave, these are correct. You can drop 1-2 lbs in the rear in the search of more grip, but the closer you are to those pressures listed below the best wear / grip balance you will have.

[mauro#749]

Thanks guys for all the value information

[Chippertheripper]

I tried a set of the dots, and now I'm on to a set of pirellis, purely because of a need for a different size tire. Now that I've ridden 2 kinds of dot race rubber I have this to say: I, personally, like the feel of the stiffer carcass better. Nohomo. The grip is about the same, so it's pretty much personal preference after that. Only problem now is, now that I'm on a motard, it'll be a while before I kill these dragons off.

[mauro#749]

Maybe my rear chock is little stif, but after I did the tire change I went to see peter gmd, and what he did to the bike was the stif the front, and soft the rear, But after he did that I been wear the tire bad, so I went and I talk to him and he say that I maybe open the gas to early, getting out of the corners,.......I check the tire pressure after every practice or race, rear cold 23- hot 28. Front cold 27- hot 30

[scottieducati]

Mauro, bring the bike by the trailer next time you're at the track. We'll get it sorted.

[mauro#749]

Cool man.....I alway bring the bike in the trailer, I be there Friday, early for practice, I pit at the campin area rigth next the stands of t3......thanks......

I don't get the whole hot tire press thing.
It's always gonna change. Going out for ftl won't generate a lot of heat but running in advanced will generate more heat.
I like cold press just because I feel its consistent.

so, let's say the track surface temp is 85 degrees one day and 125 the next?
Same cold pressure would equal very different hot pressures. Your tires are only cold in the garages, and who cares what your pressures are between the garage and hot pit?
I'd prefer to control where they end up in use as opposed to controlling where they start and having to guess about where they end up. Set them hot, right off-track, and do it religiously and you have the same pressures every time despite the varying track temps. seems more consistent, no? I hear you about FTL vs race pace, but if I need to do both I'd rather have them be a little "off" for FTL than for a faster lap. less is being demanded of the tire.
PS- I love you... and your dog.

[Degsy]

Oxx, you would have a clue if you had a relationship with a tire vendor, but that would require buying a tire and I don't think you have done that, ever.

and we all love you, partly because you're such a dumbass.

[The Snowman]

Dumb question but how different are pressures just off the track compared to having them in warmers on high?

Very different.

Would you like an expanded answer?

HEY!! just because i dont ride YOUR tires doesnt mean i dont have a relationship with a vendor. dunlop says to set them cold...thats what i do. :

i guess what i meant was...lets say you go out for a NV session, come in and set your pressures. then later you go out and...saaaay...try to keep up with me wouldnt your pressures be off?
if i set my press cold at 31/29 in the AM and go do some FTLs i know that the tires arent getting up to temp therefore wont have as much grip. but i also know that when im out at an advanced pace that when the tires get to temp they will be at the right press. i also adjust for tire wear. if i see that im melting a tire ill change it up a little.
IDK...i guess its 6 in one hand and a half dozen in the other....
you know what....IDGAFF what you people do.

[butcher bergs]

Please.

Assuming we are talking about race pace, warmers will get you close but not completely in the range of recommended hot temps. This is further exacerbated by the heat sink effect of the wheels. It would take many hours on the warmers in order to heat everything enough to where the tire would be able to effectively retain the heat and therefore attain operating temp PSI.

Gotta remember that tire warmers heat from the contact areas inward and with that, you have to heat the surface, then the belts then the air inside then the wheels if you plan on retaining any real heat. Once you are circulating on track, there is plenty of natural heat being generated by the brakes (which heats the wheels) as well as the deforming of the tire carcass....essentially two sources of heat. However the way I understand it, it's the deforming of the carcass which generates a good portion of your tire heat followed closely by friction.

I'd liken it to cooking eggs on tarmac as opposed to cooking eggs on a stove top. One method will get you close, the other will get you there.

Man, I'm going to need a LOT of help with this stuff.

I know nothing.

OXX "Hey, what pressure should I run these Dunlop take-offs that I found round the back of the scales garage, next to a trash can"

Dunlop "27 cold front, 22 cold rear"
Dunlop (quietly, to co-worker) "cheap prick"



...and I did say "buy", not "find" in my post.
