Metzler lists a 120/70 ZR 18 M/C (59W) TL, and a 160/70 B 17 M/C 79V REINFTL in their ME 880 line. Am I correct in assuming that the "59W" and "79V" are load ranges that are appropriate for the ST1300? Also, does anyone know the significance of the "TL" and "REINFTL" designations? Two Brothers guys? Other knowledgeable folks? Crazy guessers?
