Heidenau K67 3.50-19 57T TT

Heidenau K67 3.50-19 57T TT is a block-pattern tyre in the 19-inch fitment; on classic single-cylinder motorcycles this size usually works at the back — the same size the Ural Patrol carries on both wheels at once.

What K67 gives you

• Rear half of the pair: On bikes running 3.25-19 at the front, the wider Heidenau K67 3.50-19 usually goes at the back — a larger contact patch under weight and drive.
• Large block tread: Widely spaced blocks bite into earth and grass without clogging solid.
• Tube-type build (TT): Heidenau K67 is fitted with a tube — the familiar setup for spoked rims on classic single-cylinder motorcycles.
• Standalone size on heavier bikes: On the Ural Patrol, the 3.50-19 sits on both the front and the rear — with no 3.25-19 pairing.

Rubber and carcass

In the 3.50-19 size, Heidenau K67 comes without an M+S marking and without a reinforced (Reinf) carcass — it carries the rear wheel's load on mixed roads rather than deep mud. The tread holds less mud thanks to the gaps between the blocks, and on tarmac the tyre doesn't step out under drive out of a corner.

Which bikes usually take the 3.50-19 size

Heidenau K67 in the 3.50-19 size (TT, front/rear) is most often found on the rear wheel of the same classic single-cylinder motorcycles that run a 3.25-19 up front — older-generation Royal Enfield Bullet Electra Deluxe and Thunderbird TwinSpark, for instance. Separately, the same size on both axles is fitted to the Ural Patrol and Patrol T. Treat this as a guide to size, not a guarantee of fitment — check the axle and mounting against your bike's manual.

Where K67 is not the right choice

The rear-pair Heidenau K67 3.50-19 is built for mixed roads and moderate dirt, not for expedition-grade off-roading — that calls for a dedicated off-road tyre. For fast road bikes, road models with a higher speed rating are the better fit.

Who it suits

Heidenau K67 3.50-19 57T TT suits owners of classic single-cylinder motorcycles and Ural Patrol riders who need a rear or all-round wheel for everyday use: town, forest tracks, light dirt. Like its front partner the 3.25-19, this size is a favourite with scrambler and custom builders — the old-school tread does as much for the look as for the grip.
