Heidenau K34 Tyre 3.50-19 57H TT – Vintage Classic Motorcycle Tyre

The Heidenau K34 3.50-19 vintage motorcycle tyre (57H TT) is the classic block-pattern tyre of choice for Norton Commando 750 and 850 restorations, combining an authentic period-correct look with modern German rubber compound technology.

Size 3.50-19 is the correct front tyre fitment for the Norton Commando 750 and 850, making this an ideal like-for-like replacement or restoration tyre. The tube-type (TT) construction is correct for the wire-spoked wheels used on vintage British bikes. The K34 is equally at home front or rear, and is a favourite among owners of Norton Commando, BSA, Triumph, and other classic British and European motorcycles where the 19-inch rim was standard.

Heidenau uses modern silica-enhanced rubber compounds to deliver grip and longevity well beyond what original period tyres could offer. If you need confirmation on the correct tyre size for your specific model, please contact us — we are happy to advise.
