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?
Yes. I've carried a tube instead of a spare on long haul adv rides. It's a reasonable backup plan, not a daily ride option.
No, it won't make you more puncture resistant, and you absolutely do not want sealant rolling around in a moto tire fucking up your balance and making life miserable for whoever has to eventually change it.
