Just had my new set of Calli Tires whitewalls mounted. They look great and there were no issues in balancing them. White rubber adhered to a set of 205 65x15" Hankooks. We'll see how they stand up.
They look like they're at least all the way down around the rim like they're supposed to be. Mine after waiting a month were in the middle of the tire so I wasn't so pleased Sent from my iPhone using H.A.M.B.
