I would like a more narrow tire on my New World Tourist. What are my options?
We stock a wide selection of tires for the New World Tourist. The NWT can take any 406mm (20 inch) tire and you can find a reasonable selection at any bike shop that carries BMX or recumbent bicycles. We carry a wide variety of 406mm tires in our Shop Online catalog section of bikefriday.com. See the "related products" below for a sampling.
The Continental Grand Prix is the narrowest tire we stock at 1.125" width, There are quite a few at 1.35" width and up. You can get more information about a specific tire by calling us at 800-777-0258.
Note that 406 tires tend to use decimal designations, for example: 1.125", 1.35", 2.1". 451mm tires tend to use fractional designation, like 1-1/8" and 1-3/8".
