Tired of getting flat tires? Here are solutions!


Whether you are running inner tubes on your trike, or have converted over to tubeless tires, there are ways to stop getting flat tires! Here is an article by Mountain Bike Action (MBA) that compares the top eight puncture sealant products available. People use this stuff in inner tubes, and also in tubeless tires, and it works. Which products work best in which situations? Are some products better than the others? Who has time to test them all anyway? Okay, well, Mountain Bike Action has done all this for us, so read this article and choose the sealant that works best for your situation:

Article by Mountain Bike Action (an online publication):

Riders love searching for new technology that will help make them faster. Unfortunately, many upgrades are expensive and offer only a slight performance gain. Thankfully, however, there are some inexpensive upgrades that can greatly increase your bike’s performance. Any bike shop will tell you that the easiest and least-expensive upgrade is to convert your bike to tubeless. A tubeless setup is essentially a bicycle rim and tire that no longer needs an inner tube to hold air. A liquid sealant is used instead of the tube to ensure the system is airtight and also acts as a safely net in case of a small puncture out on the trail. Today, there are numerous types of tire sealant to choose from, and it can be complicated to figure out which option is best for you. So, the MBA crew decided to do the legwork for you and put the most popular sealants to the test. Special thanks goes out to Ridefast and Arisun for supplying us with rims and tires so we could perform a fair and consistent test.

    These sealants can also be injected into tubes. I developed a slow leak in my Marathon Plus (it would go flat overnight). My local bike shop sold me a small tool to remove the center “pin” of my Presta valve, and an injector/adapter that allows you to squeeze any desired amount of sealant into the tube. One or two ounces is plenty. I now have no leak at all.

  2. Guess I’m bucking the trend, but I gave up on slime years ago. When it works, it works. But when it doesn’t, like when your tube splits from of a season of unnoticed small punctures, it’s a godawful mess. Or when you encounter the annoying slow leak because the holes are too much for the slime or the slime has all settled to the bottom of the wheel. And good luck patching a slimed tube. I’ve had better luck running good tires (Marathon Plus) and carrying a spare tube and good patch kit for the very rare flat. Boise has a huge goathead problem but I’ve nearly eliminated flats since upgrading tires. I’m riding mostly on pavement, I’d consider going tubeless with one of the better sealants if focused on the backcountry. And I’d still carry a tube and patch kit…
