3.00-8" (14x3") All Weather Tire by Rolko Buyer’s Guide
The 3.00-8" (14x3") All Weather Tire by Rolko is a heavy-duty replacement tire engineered specifically for power wheelchairs and mobility scooters. Designed to handle diverse outdoor and indoor environments, it features an all-weather block tread pattern that balances superior traction, smooth rolling resistance, and exceptional durability across pavement, gravel, grass, and smooth indoor flooring.
All-Weather Block Tread Pattern
The tire features Rolko’s R-101 block tread design, optimized to maximize surface contact and water displacement. The deep grooves and structured lug pattern deliver reliable grip on wet sidewalks, loose terrain, and slippery tile, giving users confidence in year-round outdoor conditions.
Power Wheelchair Compatibility
Engineered as an industry-standard 3.00-8" (14x3") tire, it fits a wide variety of power wheelchair drive wheel rims with standard rim bead specifications (including popular Sunrise Medical, Pride, Quantum, Permobil, and Invacare models). It serves as an exact-fit replacement for worn OEM drive tires.
High Load Capacity & Durability
Built with a reinforced carcass structure, the tire is rated for heavy-duty daily use with a single-wheel load capacity of up to 375 lbs (170 kg) for pneumatic variants and 200 lbs (90 kg) for solid insert setup configurations. Its durable rubber compound resists premature tread wear and scuffing.
Non-Marking Compound Options
Formulated using non-marking rubber compounds (available in standard grey, dark grey charcoal, or non-marking black), the tire protects indoor hardwood, tile, and carpeted floors from dark streaks and scuff marks during daily indoor navigation.
Versatile Air & Foam Fill Compatibility
Designed for flexibility, this 3.00-8" tire can be installed as a traditional pneumatic tire with an inner tube for maximum air-cushioned ride comfort, or paired with a solid polyurethane/foam insert (Solid Star Keyway design) for a 100% puncture-proof, maintenance-free setup.
