That’s right, folks, Maxxis is entering the sealant market. It’s called MaxxSeal, and it’s the brand’s first tubeless bicycle tire sealant. It’s set to hit dealers in early August 2026.
While it’s designed with Maxxis Tubeless Ready tires in mind, it works with tubeless-ready tires from other brands, too. It covers a wide range of tire styles like road, gravel, urban, MTB, and downhill.
It also comes in four sizes: 250 ml, 500 ml, 1 liter, and 5 liters. So whether you’re maintaining a single bike or managing a fleet o’ bikes, there’s a size that will fit your needs.
The sealant uses a synthetic latex formula that coats the inside of the tire casing and can seal punctures up to 7 mm while you ride. Maxxis says that it will not clump up between refills, so you’re not dealing with dried chunks rattling around inside your tire.
It’s also compatible with CO2 inflation and tire inserts, and the ammonia-free formula is skin-safe and won’t damage tire casings or rim materials.
Maxxis recommends checking your sealant levels every 3–6 months. More frequently in hot climates or during heavy use. Maxxis also says that you can top off through the valve without pulling the tire off, as long as the existing sealant is still liquid.
A full refresh, which involves removing the bead and cleaning out residue, is only needed when the sealant has dried out completely or after a significant puncture.
