Hello All,

I new here and and have a question. I have a tire sized 28x1.75 or 700x45c and the tube needs to be replaced. I'm have a heck of a time finding a replacement. I found simular sized tube at WalMart (700x35/45c with a Presta valve). Not quite the right one since the old tire has a Schader valve. Question is this...is the 700x35/45c a more universal tire to fit from 35 to 45c?
