Best tires for crits?(6 posts)

Best tires for crits?LC
Jun 30, 2002 6:31 PM
I just tried some Vittoria Open Corsa CX tires on a training ride. These are supposed to be high end racing tires so I was expecting alot from them. I have this one hill I come down that makes a hard left followed by a hard right. I was not even pushing that hard but the tires were sure complaining as they squeaked and creaped sideways through the corner. I have done that same hill 100's of times, even on cheap old tires and never got a scare like that. Did this happen because they were brand new, or are they just lousy tires for cornering? I normally use Axial Pro or Pro Race, but is there something better?

Don't know about those tires specifically, but when I run my AP's at 110 I can't corner worth a damn; drop it down to 100 - 105, and I'm one counter-steering s.o.b. Speed on flats doesn't suffer one bit, either.

Just in case you didn't know,

I'm about 175 lbs, so I normally race with 115 psi. I suppose I should try some different pressures to see what effect it has.

I also noticed that the tread appears to be directional, but the tire and the directions for mounting don't say anything about it. Looks something like this, and I mounted them so the rotation is toward the top:

I'm about 175 also and when I started dropping my pressure from 115 to 100 - 105 my handling and speed increased. Again, I use AP's so it could be different. Try it for a few rides and see what happens. Start with maybe 110 and go from there.

Don't know about the tread deal. Hopefully those who have used these tires can respond.

I weigh about 178-180 during the season and usually race on open corsa tires. for a road race or a crit with wide open turns, i run 120 in the front and 125 in the rear. for tight technical crits, 110 front and 115 rear. you must allow for some deflection in the tire. I have never had any problems with open corsa washing out or coming so close to the edge of adhesion that i thought they would wash out, and this includes some pretty hairy courses in the southeast. the vittorias have a bit of a "rounder" profile than the axial pros.
for axial pros, i run the same pressures but you MUST ride them a few times before racing them. it's been my experience that they are very slick and don't grip real well when they are brand new. after a couple hundred miles they seem to corner better.
