spare tires too. nothing worse than being able to fix a tube but not the tire.
Respectfully, Scrapper; how many times have you RUINED A TIRE on a motorcycle, in contrast to HAD A FLAT?
Typically, motorcycle tires last thousands of miles; spare tubes and patch kits generally keep 'em rolling.
Your suggestion to carry a spare tire, must be DOUBLED, since front and rear tires are of different sizes.
In my view, motorcycles with spare tires lashed aboard seem not unlike scenes from the Clampett family's odyssey, on, "The Beverly Hillbillies."
Even a blown-out tire can be lashed to the rim and rolled or ridden to safety, in an emergency.
Carry extra tires if you wish; I'd concentrate on good, serviceable tires at the outset (maybe even, "run-flat" ones), possibly pre-positioned spare tires along the route (if considered necessary), spare tubes (maybe, heavy-duty ones) and patch kits.
