I have a winter bike I break out when there is Ice on the street. my set of these

was bought in 1990 and 30 years later they're still fine
though Below 0C it has been dry & cloudless in the winter, for several years.. , so low actual mileage..
My other 26" wheel bike is this
Koga WTR.
OEM Pick, Continental travel contact, shown, were great, but tread design got so many people telling me I'd worn the Knobbies down in the middle,
though they were fine, that I put Schwalbe Marathon Plus on which have been fine ever since..
