Maxxis Tubeless Ready (TR) tyres provide the benefits of a UST tubeless tyre without the weight penalty. Our TR tyres use a standard casing and require the use of a liquid sealant in order to make them airtight. Maxxis Tubeless Ready tyres are the only Maxxis tyres approved for use with liquid sealants. Using a liquid sealant in any non-TR Maxxis tyre will void the warranty.Double Down: With dual-ply 120 TPI casing and a butyl insert, Maxxis’ Double-Down technology is ideal for enduro-style rides.
