![]() ![]() If you are struggling to get the tire seated try removing the Presta valve core to allow for more airflow, reinserting the valve core when the tire is seated. Most people use an air compressor, high volume floor pump, and in some cases a CO2 cartridge. To seat the tire onto the rim you need a burst of air that will help the tire over the bead lock in the rim channel. If you have ever seen a car tire being installed and seated onto a rim, it is a similar concept to a bicycle tubeless setup. When setting up tubeless it is critical to get as much air into the tire as quickly as possible. Avoiding either one of those small tips will make the tire installation feel utterly impossible. ![]() Similarly, making sure to keep both beads off those shoulders, and inside the center channel of the rim will also make the entire process a lot less of a headache. Starting the tire installation opposite the valve is the first step to make the entire process much easier on yourself. A tubeless rim channel has two shoulders that must be prominent to maintain a constant seal around both sides of the rim channel. ![]() This isn’t due to poor products, but rather poor education about why tubeless tires must be installed differently. Tubeless tire installation, however, requires different and new techniques that can make even the most experienced mechanic struggle. Tubes have reigned supreme and trained the way many mechanics have gone about installing tires and tubes. Similarly, product offerings for road tubeless tires and wheels have been sparse till recently. While mountain bikers discovered this and adopted the technology quickly, the road bikers have been slow. Tubeless tires have revolutionized and changed the bike industry for the better. Taping is the first step, and the most critical in the tubeless setup - be sure to take your time, and do so carefully. Using a small pick to create an initial hole helps, and is the best practice. Finally, insert the valve through the tape should be done carefully to make sure the tape doesn’t tear out from the valve hole. Similarly, making sure the tape is evenly applied across the rim channel, with just a few millimeters extending up onto the sidewalls of the channel will ensure a proper seal throughout. If there are wrinkles or places where the tape hasn’t adhered, this will likely result in larger issues later. Make sure the tape fully contacts the rim, do not leave a gap between the tape and the centermost part of the rim. When starting the tape be sure to start 1-2 spoke holes before the valve stem hole and end 1-2 spoke holes past the valve stem hole. We recommend wiping it down with isopropyl alcohol to ensure proper adhesion of the tape. You must make sure the rim surface is clean. Here are the most common setup mistakes or misconceptions that lead to larger issues or a bad experience. If you don’t prioritize this, you’ll end up stranded on the side of the road.We see every mistake in the book when it comes to tubeless setups and most involve the taping of the rim and installation of the tire itself. If this doesn’t work, look for fractures in the rim and replace the damaged one. Changing the valve alone will often be enough to halt the leak. Leakage in your valve might also be caused by a damaged wheel rim gasket.Ī leaking valve can usually be repaired quickly and cheaply. The rubber seal between the metal part of the valve and the wheel rim may have worn down and is no longer sealing efficiently, resulting in air leaks and rain pouring into your tire, necessitating the replacement of both pieces. It’s possible that the valve’s core has broken. The threads on the valve stem may be stripped or damaged, necessitating a replacement. The reasons why your tire valve stem is leaking are: There are various explanations for a leaking tire valve stem, which will be discussed When this happens, it’s almost always the valve that’s leaking. Finding the source of a leak can be difficult, especially when the tire looks to be in good condition. One of the most typical sources of leaks in a tire is the valve. ![]()
