Jewish, Re tyres. Michelin knock-offs made in China maybe......... Can you supply a photo that shows Michelin on the sidewall..? because those tyres are not any Michelin tread pattern that is familiar to me for 63" rims. That, plus the fact that there appears to be very little sidewall flex, drew me to the conclusion that they were bias-ply. Try Googling Michelin XDR, XDR2 & XDS, because that's all that is available from Michelin for a 63" rim and those tyres in the photos, as they say, are "none of the above".
