My bike is only really used as a commuter, but when not dealing with heavy traffic, I do tend to push it fairly hard. My current tires are the original Dunlop Battleaxe (I think?) tires that came with the bike. They are in sad shape, and just ordered Michel Road 5s to replace them. Now I’m hearing that the Road line isn’t very puncture resistant. The city streets I commute on tend to be full of ready made puncture shrapnel, nails, screws, metal wire from tire belts, glass, you name it. Am I going to regret the Road 5s? Is there a better option for an all-weather sport commuting tire?

    Probably not in your application.

    What determines if you run a tube or not is the rim, not the tire itself. If you have a spoked rim it’s most likely you will have no choice but to use a tube. The tire valves are different between tubes and tubeless rims. On a tubeless rim, the valve stays with the rim. Otherwise it is attached to the tube.

    I guess you could theoretically install a tube anyway (after ripping out the existing valve stem) but it’s not a great idea. Heat buildup from high speed riding and cornering may cause the tube to fail unexpectedly. You won’t find anyone willing to take responsibility for it, either – not the manufacturer of the tube, nor the tire, nor the rim/bike, since you used a combination of parts not designed for the task. (The tube’s valve stem is not airtight against the rim, so if you blew a tube inside a tubeless tire on a tubeless rim, the tire itself would not leak air but the gap around the valve stem will.)

    For future readers:

    • Tubeless rim, tubeless tire: Yes
    • Tubeless rim, tube type tire: No
    • Tubed/spoked rim, tube type tire: Yes, and use a tube.
    • Tubed/spoked rim, tubeless tire: Yes, and use a tube.
