Bicycle front tire blowout?

If the tires is properly inflated, what would cause this blowout? In some places you get these little rocks and some of them are sharp. Theoretically can such pebbles put out your front tire on a road bike? What happens if you are going like 60mph at the time?

Blowouts are caused by 3 things: Puncture from a foreign object, the tube being "pinched" between the tire and the rim when you hit something like a pothole pretty hard, and from improper installation. What's interesting is that I almost never get a flat in the front tire. They are almost always in the rear tire. I figure the reasons for that are:

1. The front tire goes over a foreign object in the road and "sets it upright" into a good position to get the back tire.

2. The back tire supports much more weight than the front tire, making it more "pinchable."

3. Murphy's Law: It's much easier to remove and reinstall the front tire, so that's why flats always happen in the rear tire.

4. When you fix a flat on the rear tire, it's easy to get oily grease all over your cycling clothes. This could be a conspiracy among the laundry soap manufacturers, just like the way that the oil companies are screwing all of us now.

Most often, blowouts are caused by improper installation of the tire, leaving part of the tube under the tire's bead. Eventually, it works its way past the rim and pow! Occasionally, a sharp stone or piece of car debris can tear a hole in the tire, also causing a 'rapid loss of pressure.' That leaves a hole in the tire as well as the tube. In either case, if the tire stays on the rim and if you can hold a straight line, you'll often be able to come to a controlled stop. Some tires fit looser on the rim than others, though; and if the tire comes off, you're toast.

There are a few MUPs (Multi-Use Paths) here in Michigan, but I ride primarily in the roads. I've been in many states around the US and provinces in Canada, and I can say without a doubt that Michigan has the worst roads in North America. I can't speak for Europe or Asia, though.

A blow out at 60 mph is a cyclists' disaster. Fortunately most road cyclists don't see 60 mph often. But a blow out at 25mph is also a hand full at best.

I have never had a blown tire from pebbles. Some of the roads here still have cinders the coarseness of sand still on them from winter traction material. The biggest risk is loss of traction, not blow outs.

#43 limestone -- gravel road and driveway stone, on the other hand has cut a new Bontrager Race X Lite on my back rim. Good for me the cut stopped before the tube was damaged and I made it home without a failure.

man!!!!
u guys are lucky living in the us....where there are special lanes for bicycles....
i live in mlaysia....its in asia....
there is no dedicated lane for cyclist and the people here still think cycling is for kids...
and my neighborhood should be called pothole central...


u should check youre sidewall or check if youre tube is properly inserted....my friend while riding accidentaly went into a pothole and he blown his front tyre... 60mph!!!???
if thats true yore fast!!!

You'll probably lose control if you get a flat @ 60 mph.

Personally, I get more flats from "pinches", when I hit a large unseen pothole or object. I don't think a pebble would have too much effect at speed. Glass, on the other hand, can be an issue.
