What say the tire experts ?
An inovation or a gimmick ? I thought tire compound and not thread was
the determining factor in a tires performance/handling ... "Vittoria's innovative new reversible tires have different treads on either side" http://tinyurl.com/5vy7g |

"Vittoria's innovative new reversible tires have different treads on either side" http://tinyurl.com/5vy7g Hmmm. Interesting idea, but would probably add weight, right? Plus, that slightly grooved tread could rough up a tube, perhaps? Bill "I like Vittoria tires, but..." S. |

Tread on road tires is useless. Ergo, different tread would only b useful for off road use. But these are not cyclocross diameters so it just hype. Oh yes, and additional weight -- Weisse Luft |

Perhaps the treaded side is meant to be on the inside, where it can provide crucial traction against the rubber inner tube? Carl Fogel |

Perhaps the treaded side is meant to be on the inside, where it can provide crucial traction against the rubber inner tube? Carl Fogel Then what's up with all the tread on GP3000's? Dear SS, As far as I know, tread patterns on bicycle tires intended for pavement use is a sign of technical ignorance, the triumph of marketing or wishful thinking over well-demonstrated physics. The tread doesn't help with hydro-planing, since high-pressure bicycle tires don't hydro-plane even on the steepest descents. The tread doesn't improve traction on pavement--the same amount of rubber surface must press on the ground to support the weight of the bicycle and rider. The tread increases the rolling resistance because the rubber is freed to squirm and bulge sideways into the voids between the tread blocks. Or so I hear. Possibly someone will make a convincing argument for tread patterns on road tires, but I doubt it. Sometime around Guy Fawkes Day, I'll reach a thousand miles on the Fury RoadMaster and replace its brutal treaded tires with the smoothest, cheapest tires that WalMart offers. I suspect that my daily times will improve. Carl Fogel |
