Our Spyders, like all bikes except the Ural do not have spare tires. Getting a flat stops you dead on the road unless the cause of the flat is minor enough to allow you to make a roadside repair. I am wondering if any tire manufacturer makes a "run flat" tire that would work on a Spyder. I have a Mini which did not come with a spare, but was equipped with run flat tires and it seems to be something that would make sense for motorcycles as well, especially for three wheeled motorcycles which do not have to be able to lean in curves.
