What size tube 80G stock wheels

[glennpd]

I am planning to replace my tires, and also the 31 year old tubes. I do not know how to size the tube to match the original 3.50/19 front or the 130/16 rear.

Thanks

Glenn

The tube number will match the new tire number. 100/90-19, 130/90-16.
Where you at? I'm west of Traverse.
