Wheel with outer tire

The latest tire development ( SL Patents App.20922)

Wheel with outer tireThe wheel assembly is a combination of wheel rim, inflatable inner tire and protective outer tire. This wheel and tire assembly does not deviating existing manufacturing process or production method. The wheel assembly is a combination of inner tire and outer tire wherein the inner tire is pressed to rim while outer tire is tensed over the complete profile. Only the outer tire is needed to replace when it is worn out. The outer tire is inexpensive, saves tire materials while minimizing wastage. Outer tire
The inner tire is inflatable having its edge lips are fitted to rim edges sealing air between inner side of the inside tire while its' and outer surface is protected by outer tire. The outer tire comprises the trade layer attached with a ply strip and two shoulders connected with two beads on both sides. Further the outer tire is fastened to the rim circumference by plurality of flexible linkages with tensioners at equal intervals symmetrically. Thus, the outer tire is fitted snugly over the inflatable inner tire. The outer tire keeps the vehicle in contact with the road surface and protects the inner tire from damage and wear during propulsion and rest.


The outer tire comprises the treads profile, narrow carcass with ply layer, and two beads on both shoulders with minimized side walls. On shoulders, within the tread edge there provided accesses to hold spring loaded tensioners connected to the rim of the wheel. According to new technology, the wheel is produced with the inner tire and the outer tire. In such case inner tire may built without a tread profile.

Wheel with outer tire

The rim may provide with access to link holes in one side of the outer to other side of outer tire by tensioner cables to grip the outer tire tight. The linking tensioner cables may cross link holes in one side with the holes on the other side of the outer tire over the surface of the rim inner surface.


An alternative design of the same design:


The combination of Wheel with outer rim consists:

  • Wheel Rim: The wheel rim is the outer edge of the wheel. It holds the tire in place and provides structural support. Modern rims are often made from materials like steel, aluminum, or alloy. The rim is bolted to the hub of the vehicle.
    Tire: The tire is the doughnut-shaped elastomeric body that provides a flexible cover for the wheel. It contains an impermeable lining to hold compressed air, creating an air cushion. The tire’s tread provides traction on the road surface.
  • Wheel Hub: The hub is the central part of the wheel where the wheel bearings fit tightly. It rides on a metal axle shaft, allowing the wheel to rotate smoothly with minimal friction.
  • Wheel Bearings: These antifriction bearings enable the wheels to rotate smoothly. They consist of three basic parts: the inner race, rolling element, and outer race. Wheel bearings reduce friction between the rotating wheels and the stationary vehicle.
  • Protective Outer Tire: This detachable outer tire is designed to withstand cutting and abrasive wear from road contact. It grips over the inflatable tire and keeps the vehicle in contact with the road surface. The protective outer tire has two shoulders with beads that fasten to the wheel rim using flexible linkages and tensioners.
    In summary, the wheel assembly combines these components to allow vehicles to move smoothly while protecting the inner tire from damage. If the outer tire wears out, it can be replaced independently of the rest of the wheel assembly.

    Let’s explore the advantages of the described wheel assembly design:

    Improved Durability and Wear Resistance:
    The protective outer tire shields the inner inflatable tire from direct contact with the road surface. As a result, it reduces wear and tear on the inner tire due to road abrasion, sharp objects, and cuts.
    By preventing damage to the inner tire, the overall lifespan of the wheel assembly is extended.
    Enhanced Safety:
    The protective outer tire acts as a buffer, absorbing impact forces from road irregularities (such as potholes or debris). This helps maintain better stability and control during driving.
    In case of a blowout or puncture, the outer tire provides an additional layer of protection, allowing the vehicle to continue moving safely until the inner tire can be replaced.
    Ease of Maintenance:
    Since the protective outer tire is detachable, it can be replaced independently of the rest of the wheel assembly. This simplifies maintenance and reduces downtime.
    Mechanics can easily remove and replace the outer tire without disassembling the entire wheel.
    Cost Savings:
    Instead of replacing the entire wheel assembly when the tire wears out, vehicle owners can replace only the outer tire. This cost-effective approach saves money in the long run.
    Additionally, the protective outer tire helps prevent costly damage to the inner tire, reducing the need for frequent replacements.
    The design allows for flexibility in choosing different protective outer tires. Vehicle owners can select outer tires with varying tread patterns, materials, and performance characteristics.
    Customization options cater to specific driving conditions, such as off-road, highway, or winter driving.

    In summary, this wheel assembly design offers improved durability, safety, ease of maintenance, cost savings, and customization options. It’s a practical solution for vehicles and carriages that need reliable performance on various road surfaces.


    The product is to be manufactured in a factory with a ply layer and two beads attached to the tread layer for best performance. We are looking for an entrepreneur or investor to finance to custom product manufacture.
