Goodyear Newton Enduro Tubeless Rear MTB TyreThis mountain bike (MTB) tyre is designed for modern enduro racing and it's ready for the most demanding of course conditions. It features a Dynamic:Grip3 compound that uses triple3 density rubber to deliver balanced levels of grip and treadwear. Goodyear has also made this version specifically for your rear wheel with a rear tread pattern that focuses on acceleration and braking traction. Another highlight is its EN:Wall sidewall protection, which uses a Butyl insert to provide extra sidewall support while also protecting against cuts. In addition, its dual ply construction uses two layers of 120 TPI casing fabric to further enhance this model's enduro level protection and sidewall stiffness.Enduro Rear Tyre with Tubeless Complete DesignThe Newton MTR (Mountain Rear) is part of Goodyear's ultimate tyre package developed for gravity riding and racing. A tyre that is at its best bringing up the rear while sprinting out the start hut of your race run, as you attack those loose off camber sections, hold the line on rocky chutes and pinballing down rock sections. It features a Tubeless Complete design that offers the same benefits as tubeless-ready (TLR) technology, while also maintaining inflation pressure better than a traditional TLR tyre.
