Tubes a size too small . . . No harm No foul?
I recently got a new wheelset and needed some long stem tubes. It was late and my LBS was closed and I wanted to ride in the morning so I went to REI. I'm running Ultra Gatorskins (28's). Rei was out of tube sizes 700 x 26-32, so I got 700 x 20-25.
Even though it has worked so far, what's the downside of this? Am I at slightly more risk for a blow out since the tube is stretched thinner? I'm also in some extreme temps in Arizona, so road surface temps can be off the charts.
All I can think about are those poor SUV's flipping over from blowouts with Firestone tires some years ago. (Although after reading the reviews about Novara tubes, maybe I should just be worried about poor quality.)
