Vittoria Zaffiro Pro tyres have been available for some time in an all white colour. I have rode a pair of these on my fixed gear commuter last summer. They look fab to spruce up a tired old looking commuter, and decent enough tyres for pootling around the city streets. Only a 60TPI casing on them, so not as durable in the puncture protection stakes as the Rubino or other such models. Cop for £11.95 with free postage over at Merlin Cycles.
