I actually have other Schwalbe tires, Lugano Folding and the Milano tubulars, thats what prompted me to buy these instead of the Pasela. I agree, I must have gotten a Lemon, I suppose it happens from time to time. I know they weren't made in the hidden Jungle facility were they keep the genetically modified silkworms, but the quality of these tires is quite poor next to the (same price) Pasela.
