Overview

Upgrade your 4.80/4.00-8 tires with SPORTYOUTH inner tubes. This 2-pack features a TR-13 straight valve and a robust rubber compound designed to deliver reliable service across lawn tools, carts, and more.

Key benefits

  • Perfect fit for 4.80/4.00-8 tires (8 in rims, 15.5 in OD), replacement without buying a new tire.
  • Heavy-duty rubber, approximately 4X thicker than standard tubes, promoting better air tightness and aging resistance.
  • TR-13 straight valve for straightforward inflation; valve orientation helps easy mounting on many wheels.
  • Two tubes per pack save time and reduce downtime when maintenance is required.

Real-world use

Whether you're tending a lawn, hauling soil with a wheelbarrow, or moving gear on a small trailer, these inner tubes are designed to complement equipment you rely on. The 2-pack provides peace of mind for businesses and serious DIYers alike.

  • Lawn care: replace a punctured tube in your mower or cart and keep working without waiting for a service call.
  • Material handling: fit your hand truck or dolly to keep projects moving smoothly around the yard.
  • Seasonal equipment: suitable for generators, snow blowers, pressure washers, and trailers that use the 8 inch rim size.

Usage tips

Note not for road use. Maximum 30 psi. Inflate with a manual pump to avoid overfilling. Check size before purchase and follow safe mounting practices to ensure a proper seal.

Installation at a glance

Install in minutes: remove the old tube, lay the new tube inside the tire, align the valve, reseat the tire, and inflate gradually until reaching the maximum recommended pressure.
