Got a flat on your lawn tractor, golf cart, or small trailer? This Firestone inner tube will get you rolling again! It's designed to fit multiple tire sizes: 4.80-8, 4.00-8, 4.00-9, and even 4.80-9 tires. The section width is 4.80, and it's made for 8-inch rims (but stretches to fit 9-inch too). Comes with a standard TR13 valve stem. Brand new in the package, part number 533-149. These tubes are tough and reliable - just what you need for equipment that takes a beating. Keep one in your garage for emergencies, or replace that leaky tube that's been giving you trouble. Much cheaper than buying a whole new tire!
