The Donnastreet is our new tire, based on the same proven rubber as the popular Donnasqueak tire but with a smoother lower profile tread. The tread sits further round the sidewall (where the tire contacts when grinding) and because the tread is smooth (no knobs) then it doesn't snag when grinding - also the sidewall life is prolonged due to this...
– Smooth centre for low rolling resistance
– Extra grippy & super squeaky compound
