Product Description Note from the Manufacturer:Maxxis strongly advises against the use of ammonia-based sealant. Ammonia has been proven to attack the carcass and can weaken it by up to 30% after only a few months, depending on the amount used. Guidelines for replacing E-bike components:Before you replace components on your e-bike, please read through the guidelines for component replacement for CE-marked e-bikes/pedelecs with pedal assistance.

The arrangement of the compounds is planned individually according to the desired properties of Maxxis tyres. MaxxShield (MS) MaxxShield is the ultimate puncture protection. Maxxis takes the Silk-Shield all-round protection and adds the K2 (Kevlar Composite) layer for the best possible protection. Tubeless Ready Tubeless tyres have many advantages: you can ride with less air pressure. This gives better traction and reduces rolling resistance. And where there is no tube, the risk of punctures is reduced. Maxxis TR tyres are better prepared for mounting with sealant than other " tubeless ready" tyres. The bead of the Maxxis TR tyres is completely covered with a rubber layer like a real UST tubeless tyre. As a result, tubeless mounting is successful for all rims with standard dimensions even during the first inflation and with little liquid.
