How do you seat a stubborn bike tire bead?

Lift, squeeze and massage the tire until the tube no long appears under the bead. Then cautiously add air, watching to make sure all is well. In a properly seated tire, the bead line — the thin line molded low on each sidewall — will be just above the rim all the way around on both sides.

How do you know if your bike tires are seated?

To tell if a tire is seated properly (even old tires might not be fully seated), you look at the seat line that’s molded into every tire (photo). When a tire is properly seated, that line sits right on top of the rim, equidistant from the rim for 360 degrees around the wheel and on both sides.

Why does my road bike tire keep popping?

It can also be caused by a tire that has not been seated properly to begin with or by a hook that has been damaged. It will usually destroy the tube beyond repair. Solution: make sure the tire is seated properly before inflating it to full pressure. You may need to replace either the tire or the rim.

What causes a bulge in a bike tire?

In the case of the tire, it may not have been properly seated on the rim prior to inflation. Once under pressure the tube will push through this section of the tire and form a bulge. Once you hit the trail this problem can deteriorate causing the tube to rupture and possibly shred the tire in the process.

Why does my inner tube bulge?

Make sure the tube is not pinched between the tire and rim. Make sure the reenforced valve area of the tube is pushed up into the tire. Make sure the tire is evenly seated on the bead all the way around. There is often a line moulded into the tire around the bead that lines up with the rim you can use a a reference.

Why do my tubeless tires go flat?

Air leaks out of any tire, whether a tube is used or not. While some tubeless clincher tire/rim combinations actually hold air better than a standard tube, many lose air pressure faster than a conventional tube tire. If the tire deflates, the seal between the tire bead and rim can be lost.

How long do tubeless tires hold air?

It will lose a few PSI over the first few days, but then it will hold 3 or 4 psi for 6 months of storage.

How much does tubeless tire sealant cost?

For a standard mountain bike tire, we recommend 2-3 ounces of sealant. You may want to use 3-4 ounces in larger mountain bike tires or for the initial setup in tires that you find difficult to seal. We use about 4-5 ounces in FAT tires. For road and cyclocross tires we also recommend 2 ounces.
