The Donnastreet tires are based on the massive success that BSD has had with their Donnasqueak tires. The rubber compound is still the tried and tested compound from the Squeaky tires but instead with an all over smoother tire tread for more grip, whereas the sides on the tire-walls are more round which provides a better tire for grind tricks.
The tires have a smooth center that lowers the overall rolling resistance. The casing is made with the BSD Silkworm material that is tear resistant.
