Replacement tubes for 4.80/4.00-8" tires / wheels (15.5" outside diameter)
Material : Isobutylene Isoprene Rubber which is better in air tightness, elastic damping and aging resistance than natural rubber.
No need to buy a new tire when you have a flat, simply replace the tube and you'll be back up and running
Please check the sidewall of your tire - if it says "4.00-8", "4.80/4.00-8", or "4.80-8" then this tube will likely work
Package Included: 2 x Inner Tubes
