Here's another nasty wrinkle. Your friendly neighborhood service department is obligated to be knowledgeable, and install safe equipment on your bike. By installing non-recommended speed-rated tires, they put themselves at legal risk. When I was a service manager many years ago, the customer had to sign a disclaimer if he supplied a used or non-spec tire.
