On our tug, the front tire spec'd is a 110/90-18, with a nominal OD of 25.8"

The Heidenau K-28, a square profile sidecar tire, is 4.00-18, with a nominal OD 26.4.

Even though the K-28 is specified for a slightly narrower rim width, and has a slightly larger OD, I'm thinking that this won't be a big deal, and that the OD once fitted to the rim will be roughly the same, the K-28 should work just fine, and will be better for the application than a 'straight' M/C tire.

True or false?

TIA,
Michael

When fitting a special sidecar tire from Avon to a 19 " rim on a Suzuki S-40, I had to lift the front fender to gain clearance.
You may have the same problem.

What was the tire on the S-40?

Was it worth any drama?

  19 inch X350 stock I believe it was the same for the Avon sidecar special.

   Shown here with a Harley sportster front fender which gave much better rain protection.

   Also note the comfort to be had from the 1965 Harley buddy saddle

Had one of those Custom Chrome front fenders on my '87 FXLR/Springer conversion. Sure kept the crotch dry in the rain.
Later I dumped the primitive poorly made Sputnik for a more comfortable Velorex 562.

K-28 (tire) showed up right after Thanksgiving, mounted it on New Year's Day. Close fit, but didn't need to move the front fender.

Took it out today and WOW! No more low speed head shake (even without ballast), no notable increase in turning effort, and picked up 1/2" extra ground clearance in front. Even new, cornering grip is improved as well.

All plus, no negatives!
