The best explanation I've seen on this is from Sheldon Brown. https://www.sheldonbrown.com/tire-sizing.html
"If your tire is too narrow for the rim, there's an increased risk of tire/rim damage from road hazards. If its too wide for the rim, there's an increase risk of sidewall wear from brake shoes, and a greater risk of loss of control in the event of a sudden flat." A little lower on the page he provides a "what fits what" chart, and states: "Note: This chart may err a bit on the side of caution. Many cyclists exceed the recommended widths with no problem" I'm running Conti Speed Ride 42s on Atlas rims no problem. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
