ATTACHMT: ATTACHED TO LETTER DATED 12/01/88 FROM ERIKA Z. JONES TO GARRY GALLAGHER; REDBOOK A33, STANDARD 119
TEXT: Dear Larry,
Per our phone conversation back on June 15, 1988. I am requesting a written determination in regards to specific requirements within the size designations on the side walls of motorcycle tires.
My inquiry involves code #571.119 - section S6.5-c. As you may recall, my specific question was whether the letter B was required within the size designation if the tire is of bias-belted construction.
As Metzeler Motorcycle tires are manufactured in Germany, we meet the sizing requirements and listings of the E.T.R.T.O.
A Metzeler bias-belted tire is marked with both the number of plies and material of the plies of both the tread and sidewalls of the carcas. The letter B is sometimes added to the size as an internal code.
Your verbal determination over the phone was that the letter B was not an actual requirement. This letter serves to request a written determination.
Thank you for your assistance. Please call me if you have any further information or questions.
