The same tires as in dry weather.
The tire in a road bike is so narrow that it is not necessary to evacuate the water as in a car or
motorcycle."guess who" <[email hidden]> escribió en el mensaje

Then why do they make tires for wet racing? Surely the extra traction helps in corners.
They don't. They _sell_ tires for wet racing. These tires are prettied up with fancy graphics, and
have all sorts of marketing claims laid on them. But in reality, they perform no better (and often
worse) than regular tires on wet roads.Mark McMaster [email hidden]

munufactured for low rolling resistance. Both probably bad ideas considering the conditions.Art Harris

I heard that Armstrong was considering using a narrower tire on the front only. Given the early
reports from his teammates, I'd be surprised if they went with it in the end.I've always heard that natural rubber tires (e.g. Continentals) are much better at maintaining
traction in the rain than the typical synthetics. Sheldon? --Shayana Kadidal -

According to Continental's own literature, regular carbon black rubber (not silica) gives the best
grip in wet conditions:conti-online.comasc en.htmlOpen ↗

I watched the stage with a friend who has been in the "pits" in simialer conditions and said the
machanics were shiittting twinkies with all the last minute changes of setup.... he even ventured
that Jan's bike may not have been setup to the exacting specs required.. but then we were here in
the states and not there so it's all speculation.Mark McMaster said:

I spoke to an engineer at COnti - and he basically said, on a 20mm piece of rubber, no tire will
give you traction when it is wet.Regardless of what they say, if it is wet, you are going down if you push it - and yes, Lance went
with the narrow front wheel. -

best grip in wet conditions:Right, sorry. I thought the silica was added for grip, but as they say, its for better adhesion on
_dry_ surfaces. On their website it appears that all of their racing tires have silica in the tread
but they do make mention of some special tires made for their sponsored teams.-WG
