Wanna Place Your Bets?

I heard a "click clikck click" about a mile into my commute this morning, pulled over and discovered what looks like a drywall nail in my rear tire.

It didn't seem to be losing air so I chanced it and rode the rest of the way in.

What's the over/under on it being flat by the end of the day?

How small was the nail and what are the tires? Any liners inside?

I don't know what size the nail is....I'm leaving it in there until the end of the day.

No liners and the tires are Panaracer Pasela TG. At first I considered it to possibly be a tack but the head is dimpled like a drywall nail.

Flat - 100%
Rim damage - 50%

Last time my bike took a drywall screw, it poked dozens of holes in my brand new wheels.

why are you leaving the nail in there? Take it out. Then if it is going to go flat you can fix it on your lunch hour or before you leave work.

The nice thing about that nail is that it makes a nice plug for the hole it created, so I imagine the tire'll still have some air come the end of the day.

How far do you reckon you rode with that nail in the tire?

That has happened to me a couple of times. Once it flatted quickly, the other time I wasn't far from home and turned around and rode back to fix it in the comfort of my garage. I'm going to guess it will be flat by the end of the day.

Yeah I didn't consider rim damage until I got to work. Hopefully it's OK.

I'll leave it there until the end of the day and pull it/replace the tube before I leave for home.

I won't bet one way or the other, but I'm interested to see how this ends.

At the end of the day...

It was very close to being flat. Not sure what kind of nail this is but it isn't as long as the drywall nails I'm familiar with. No damage except for the tube.

Your priorities are all messed up. Bike repair should be first, work second.

Got lucky with what looks to be a half-incher

Trust me, fix it next time. You don't want the pain of poking 20 holes on the first ride after you bought brand new wheels.

Roofing nail makes sense and I'll put more priority into fixing it next time. I figured I'd do the experiment to see how long it would hold air. If anything, around here flats are caused by thorns or the occasional piece of glass or metal shard so the nail was a surprise.

Ride safe!

Yeah those roofing nails can easily point straight up thanks to their relatively short shank and wide head.
