Tube size?

[blue giant]

I'm ordering new tires and inner tubes for my project bike and the site lists a tube size of 170/80-15 for the rear wheel of my 79F.

I would have thought the last number would be 17 as I have a 17" rim.

The number for the front tube is 100/30-19 for a 19" rim.

Does this sound right?

Thanks,

Paul

Is this info listed in the factory manual?

rear tire size

15'' sounds small . My rear is a 16" .

I just checked the factory manual and it does not list any info about the tube size.
