SJS Customer Service:

Hello, Please use the ETRTO code on the tyre to confirm tube compatibility. This is usually found on the tyre sidewall and is a two-digit number followed by a three-digit number. Please confirm this prior to ordering a tube to fit.

For your tyres we would actually recommend the standard SV12 tubes which are part number 13007.
