Jim;
I highly doubt that your tires have those stampings, more likely your rims have those stampings.
More like the tires are marked something like 35-622. In which case, I suggest these tubes if you need Presta valves:
Sunlite Thorn Resistant Bicycle Tube, 700 x 35-40 (27 x 1-3/8) 32mm PRESTA Valve
and for Schrader valves:
Sunlite Thorn Resistant Bicycle Tube 27 x 1-1/4 (700 x 30-35) SCHRADER Valve
I use the 35-40 tube for tires ranging from 28-622 to 40-622.
I have changed all my bikes to Presta valves, using collars on the rims that are drilled for Schrader:
Wheels Manufacturing Alloy PRESTA Valve Saver (2/bag)
