Why do I always get punctures in the back wheel?

by
Filed under: punctures 

9 times out of 10, if I get a puncture it is in the back wheel. Had to push the bike home today because of yet another puncture.

The front tire “sets up” the foreign object so that it can penetrate the rear tire. There is also more weight on the rear tire, helping the object to drive through the tire’s body, each rotation like one of a hammer’s multiple blows to drive in a nail.

    2. Don’t know but im glad you asked because ive noticed that to!! weired!! Could be because most of the weight is on the back wheel as you sit right above it!

    3. The answer is, you actualy run over the sharp object lying flat, with the front wheel first which disturbs it into a position that causes it to puncture the following wheel.
    Had this happen on my motorbike with a stanley blade which was found inside the tyre when it was removed. Brand new tyre with less than 300 miles on, $5%%3$ӣ !!

    5. Weight is the main reason. In AZ we used to get them from cactus needles. In FL we get them from sand spurs. If you are not a racer, I would suggest you buy a shield for the tire. It is a white plastic flexable ring that sits between tire and tube. Very effective at stopping punctures.

    7. Because more of your weight is on the back tire. But, it is better than getting a flat in the front tire, since you would lose steering immediately with a flat front, not a fun thing to happen if you’re blasting down a hill.
    Rear tire wears out faster too, that may also explain the more frequent flats.
    I suggest you should carry a saddle bag carrying a spare tube, patches, tire lever, and a hand pump. That way you can patch and continue to ride home instead of walking miles home.

    8. it depends where you ride your bike mostof the time this is called a pinch flat. it is most likely that your tire pressure is to low and when you ride your bike your weight puts more weight tham the tire can handle at the pressure so what happens is that your inner tube gets a pinch from both sides.
    try to messure your tire pressure it should tell you on your tire how much tire pressure you need. if you go with the higher tire preesure you have a better chance of avoiding flats. usually the tire pressure should be from 45-65 if so put 60psi or 65 psi again it all depends on where you ride.

    9. all i can really say is just keep your tire pressure good, and just try to avoid em.
