BSD's Donnastreet is built for the streets, based on their proven rubber compound from the Donnasqueak tyres, making this one of the most popular tyres they offer. The Kevlar bead version of the Donnastreet tyre is based on the same priven rubber and tread design as the original, with the added benefit of being lighter and foldable. They feature an all over smoother tread for more grip and sidewalls which sit further round the rim for better grind performance. Max pressure rating: 110psi. ###section### Product Specs WHEEL SIZE: 20" MAX PRESSURE: 110 PSI WEIGHT: 670g (23.6oz) PACK SIZE: Single
