Airless tires, non-pneumatic tires (NPT), or flat-free tires are tires that are not supported by air pressure.[1][2][3] They can be used on small vehicles such as ride-on lawn mowers and motorized golf carts. They also are used on heavy equipment required to operate on sites where risk of tire punctures is high. Tires composed of closed-cell polyurethane foam are also made for bicycles and wheelchairs.[4]

Advantages & disadvantages

The main advantages of airless tires is that they do not go flat and need to be replaced less frequently. Heavy equipment outfitted with airless tires will be able to carry more weight and engage in more rugged activities.[5]

Airless tires generally have higher rolling resistance and provide somewhat less suspension than similarly shaped and sized pneumatic tires. Other problems for airless heavy equipment tires include dissipating the heat buildup that occurs when they are driven. Airless tires are often filled with compressed polymers (plastic) rather than air, or can be a solid molded product.

Airless tires are attractive to cyclists, as bicycle tires are much more vulnerable to punctures than motor vehicle tires.

The drawbacks to airless tires depend on the use. Heavy equipment operators who use machinery with solid tires may become fatigued. Any airless tire will be heavier than the rubber tire it is meant to replace.

However, airless tires are not popular with hardcore off-roaders, as those vehicles often need to travel long distances at highway speeds. At speeds above 80 km/h, they can be unstable, causing severe vibrations (and passenger discomfort), and therefore potential for drivers to lose vehicle control.[6]

Installation of airless tires depends on the use. Heavy equipment will need special equipment to mount, but an airless bicycle tire can be mounted with little effort. Solid airless lawnmower tires come pre-installed on the wheel, allowing quick installation.[citation needed]

Many bicycle-sharing systems use these tires to reduce maintenance.

In 1938, J. V. Martin in the United States invented a safety tire with hoops of hickory encased in rubber and fitted with criss cross spokes of ribbed rubber. It could drive over 100 mm (4 inches) blocks when tested in a springless test car.[7]

In 2005, Michelin started developing an integrated tire and wheel combination, the "Tweel" (derived from "tire" and "wheel," which are combined into one new, fused part), which operates entirely without air. Michelin claims its "Tweel" has load carrying, shock absorbing, and handling characteristics that compare favorably to conventional pneumatic tires.[8] However, the tire has a lot of vibration when driving over 80 km/h (50 mph). Therefore the tire is only available for golf carts, ATV's and skid steer vehicles. In 2019 however Michelin and GM announced their goal of making a new airless tire for passenger vehicles available in 2024. [9] The automotive engineering group of the mechanical engineering department at Clemson University is developing a low energy loss airless tire with Michelin through the NIST ATP project.

Resilient Technologies and the University of Wisconsin–Madison's Polymer Engineering Center are creating a "non-pneumatic tire", which is a round polymeric honeycomb wrapped with a thick, black tread. The initial version of the tire is for the Humvee and is expected to be available in 2012.[10][11] It is also the first group to make a commercially available mass-produced airless tire after its acquisition by Polaris,[12] albeit only as coupled with their vehicle. The tire trademark is "Terrainarmor".

Bridgestone is developing the Bridgestone Air-Free Concept Tire, which can hold 150 kg (330 lb) per tire.[13]

The Energy return wheel (ERW) has the outer edge of the tire connected to the inner rim by a system of springs. The springs can have their tension changed to vary the handling characteristics.[14]

Hankook is developing the iFlex airless tire.[15]

However, many tire manufacturing companies are yet to start making airless tire due to different limitations. Major companies like Goodyear say its airless tires won't be road-ready until 2030.[16]

Electric scooters have rapidly surged in popularity as an eco-friendly and convenient mode of urban transportation. With the rise in usage, the importance of understanding and selecting the right tires for electric scooters has become paramount. One of the significant debates in this realm centers on the choice between pneumatic and solid tires—two distinct options each bearing its own set of advantages and disadvantages

Electric scooter tires, the sole point of contact between your scooter and the road, play a pivotal role in determining the overall riding experience. They affect how your scooter handles different terrains, absorbs shocks, and maintains traction, making them a crucial element in ensuring a safe and enjoyable ride

When it comes to choosing between pneumatic and solid tires for your electric scooter, there's no one-size-fits-all answer. The optimal tire type varies based on a multitude of factors, such as your riding environment, frequency of use, desired comfort level, maintenance preferences, and budget constraints

Ultimately, your decision should align with your individual preferences and requirements to ensure a seamless and enjoyable riding experience.

Part 1. Two Types of Electric Scooter Tires

A. Pneumatic Tires

Pneumatic tires, as the name suggests, are designed with an internal chamber that contains air, giving them a cushioning effect and the ability to absorb shocks and vibrations. They are constructed with an inner tube that holds the air and an outer rubber layer that provides traction and durability. The air-filled design allows these tires to absorb shocks and provide a smoother ride by cushioning the impact of bumps and uneven surfaces on the road.

There are two subtypes of Pneumatic Tires:

1. Tubeless Tires:

Tubeless pneumatic tires are becoming increasingly popular in the world of electric scooters. These tires eliminate the need for an inner tube, relying on a special lining within the tire to maintain air pressure. It's a suitable choice for riders seeking a versatile and low-maintenance option.

2. Tires with Tubes:

Tires with tubes, like those found on the TurboAnt M10 Lite, and the TurboAnt X7 Max, boasting a powerful 350W brushless motor and a range of up to 32 miles, features 10-inch tubeless pneumatic tires. This design not only reduces the risk of punctures but also makes for easier maintenance.

TurboAnt M10 Lite comes with a separate inner tube that holds the air. The M10 Lite, equipped with a 350W brushless motor, offers a maximum range of 15.5 miles and a top speed of 16 mph. Its 8.5-inch pneumatic tires provide a comfortable ride on various surfaces. Additionally, this model features a 3-second quick folding mechanism, a USB charging port, and a dual braking system with disc and electronic brakes, enhancing both safety and convenience.

B. Solid Tires

Solid tires are a popular choice for electric scooters due to their durability and low maintenance. Unlike pneumatic tires, solid tires do not contain an inner tube filled with air. Instead, they are made of solid, dense material that is puncture-proof, providing a hassle-free riding experience. The composition of solid tires typically includes a mix of rubber, plastic, and other polymers, ensuring a long-lasting and resilient tire surface.

These tires are designed to offer resistance to wear and tear, making them a practical option for those seeking longevity and minimal upkeep.

They are classified under three types:

1. Fully Solid Tires:

Fully-solid tires are made entirely of a dense rubber or rubber-like material, ensuring they are entirely puncture-proof and maintenance-free. These tires provide a smooth and consistent ride, ideal for city commuting.

2. Honeycomb Solid Tires:

Honeycomb solid tires feature a unique hexagonal honeycomb structure within the tire. This design offers a balance between comfort and durability, providing a relatively smoother ride compared to fully-solid tires. The honeycomb structure allows for some shock absorption while maintaining puncture resistance.

The TurboAnt V8 E-Scooter has two tire options including 9.3-inch pneumatic tires and 9.5-inch honeycomb tires, featuring a powerful 450W brushless motor and dual 7.5Ah batteries. With a maximum range of 50 miles and a top speed of 20 mph, this scooter offers a comfortable and dependable ride for urban travelers.

3. Foam-Filled Tires:

Foam-filled tires are solid tires that are injected with foam to mimic the cushioning effect of air-filled tires. While not as soft as pneumatic tires, foam-filled solid tires offer a compromise between comfort and maintenance. They can handle varying terrains while still being resistant to punctures.
