Me about 90 kg , rear paniers and light maybe 5 to 7 kg load , mostly flat 40 km everyday and any weather riding , 90 % riding on fast aspalt in bicycle line . Bike is older, restored and slightly modified treking model Koga Miata , 27 spead and I run 52 - 11 gear on it . I think Shwalbe Marathon or Panaracer Pasela . There is more option from Continental , Michelin and so on . Which tire will perform better ? Any idea ?
