Why Does My Road Bike Tire Keep Popping?

Everyone knows how frustrating a flat or popped tire can be when bike riding. But what if your road bike’s tire continuously keeps popping or deflating? What are the causes for a bike tire that keeps popping, and how can you fix it?

There are several reasons why your bike tire keeps popping, such as the tire pressure being too much, the temperature being too hot, or the rim is bent or damaged. If something is lodged in the outer tire, it can also cause your tube to pop. Fortunately, most of these problems are easily fixed.

If your road bike’s tire keeps popping without explanation, you might look in the wrong place to find the cause. We’ll discuss the common causes for a road bike’s tire to pop and how you can solve the problem.

Road Bike Tire Keeps Popping – Causes And Solutions

Having a popping or deflated tire is highly frustrating when you’re out riding a bike or just about to start a ride. Even more frustrating, though, is having your tire pop continuously, even after fixing the supposed problem.

There are several reasons your road bike’s tire may keep popping or deflating, and each problem has a unique solution. Let’s consider 6 reasons your road bike tires keep popping or deflating and how you can fix them.

1. Sharp Object On Road

Nails, glass, and wires on the road may stab into your road bike’s tire while you’re riding and could cause the tire to pop or deflate. Most road cyclists experience a popped tire due to shrapnel on the road from time to time, but a few unfortunate souls have had this problem several times in a single ride.

It isn’t much you can do to prevent this from happening since you can’t always see the objects on the road until it is too late. The best way to prepare for this case is to carry a patch kit and spare tubes while riding.

Keep a close eye on the trail or road, and don’t ride over any clear obstacles in your way. For example, if you see plenty of shards of glass lying in the road, drive around them instead of through, or try taking an alternative route.

2. Incorrect Tire Pressure

If the tire pressure of your road bike’s tires is too much, the tires may pop somewhere during your ride. As you ride your bike, the air inside the tire becomes warmer, causing it to expand the tire even more. Having your tires too hard from the start may lead to popped tires later in the cycle.

If you notice popping tires frequently after pumping them, it might be because you are filling them with too much air. Check the manufacturer’s recommended tire pressure for your tires and consider your weight or the rider’s weight as a potential factor.

The air pressure plays an even more critical role when the temperatures are higher. The hotter the day, the more the air inside the tire will expand. So ensure your tires aren’t overinflated when riding in hotter climes when you will ride for longer distances.

3. Something Sharp Lodged In The Tire

It’s also possible that your tire keeps popping because something sharp is lodged inside the outer tire or something is stuck between the tire and tube. In this case, patching the tire won’t do any good since it will only pop again once you start riding.

If your tires frequently pop, remove the outer tire and check for any damage or objects stuck between the tire and tube. This may not be obvious to spot, so you might have to submerge the tire in water to see if there are any leaks or faults.

4. Bent Rim

Another problem that can lead to your tires popping or deflating is a bent or damaged rim. If the rim is bent, it can stab the tube while you are riding. This can cause the tube to burst. A cracked rim can pinch the tube and cause it to pop while riding.

If you were in an accident with your bike, it’s essential to check for any damage that may have occurred to your rims. Although the rim may look fine at first glance, any damage can cause your tires to pop or deflate, influencing the overall ride quality and safety.

5. Old Tires

Since bike tires start deteriorating with age, it’s also possible that your road bike’s tires start popping and deflating because of old age. This is more common if your bike has been standing around for a while without being ridden. As the tubes age, they start getting brittle, which causes them to deflate for pop.

If you notice your bike tires deflating or popping more often, take the tubes out and check their condition. If your tubes look old and weathered or start to crumble or break apart, it’s time to switch out the tube for new ones.

6. Rot Or Mold

Finally, your tires may also pop or deflate if the tires have developed dry rot. Dry rot is when the tires stand around for a long time without being used or when there is a lot of moisture in the air. Dry rot also causes the tires to become brittle, which may lead to cracks and leaks.

Again, if your tires have been in your bike for a while, or your bike has been standing around for a while, it might be worth taking them off and inspecting the condition of the tubes. Having rotten tubes will undoubtedly lead to popping or deflating tires.

How To Prevent A Road Bike’s Tire From Popping

Suppose you want to avoid your road bike’s tires popping or deflating. In that case, you can take some preventative measures to reduce the chances of that happening. Here are some preventative measures that can help reduce the chances of your road bike’s tires popping:

  • Ensure the tire pressure is correct before and during the ride, especially on hot days.
  • Check the condition of your tires, rims, and tubes before going on a ride.
  • Avoid obvious obstructions in the road that can puncture your tires.
  • Bring a tire repair kit, sludge, and spare tubes when going on a ride so you can replace or fix the tire if need be.
  • Replace your tubes if your bike has been in a humid environment for a while.

Following these tips can reduce the chances of your bike’s tires popping or deflating. Of course, there is never a 100% guarantee that you won’t suffer from popped tires on your road bike once in a while.


Common causes for popping road bike tires include rot or mold, old tires, incorrect air pressure, a damaged rim, obstructions in the tire, or sharp objects on the road. You can take some preventive measures to reduce the likelihood of the tires popping, but there is always a chance of it happening.
