Why can’t cars have airless tires?
Airless tires need to be much larger than air tires in order to support the weight of a vehicle. More road contact means more resistance and worse handling and gas mileage. Airless tires have ride comfort issues similar to the solid rubber bicycle tires of the 1800s. Airless tires are stiffer than rubber, so they tend to maintain their shape for longer. One of the main factors in the reduction of fuel efficiency is tire deformation. With these puncture-proof tires, your vehicle should have the same or even better fuel efficiency than it would with traditional tires.Unlike traditional pneumatic tires that depend on air pressure to keep their shape and offer cushioning, airless tires are constructed from solid materials and are built to withstand enormous loads and rugged terrain.Cost: The advanced materials and technology used in airless tires can make them more expensive than traditional tires.Airless tires need to be much larger than air tires in order to support the weight of a vehicle.

Why did airless tires fail?
Current airless prototypes tend to transfer more road noise and vibration into the cabin than traditional radials — making the ride harsher, especially at highway speeds. Heat buildup is another issue. At high speeds, traditional tires dissipate heat through their air volume and structure. Noise – the current air-filled tire industry often has a focus on noise reduction technology because nobody likes a noisy ride! Unfortunately, airless tires are nowhere near quiet enough for the average vehicle driver.Current airless prototypes tend to transfer more road noise and vibration into the cabin than traditional radials — making the ride harsher, especially at highway speeds.

Can airless tires go flat?
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. Run-flat tyres last about the same time as regular tyres – so between 25,000 and 50,000 miles. Just as with a traditional tyre, a run-flat tyre’s lifespan can vary depending on factors like: Brand – some brands are simply more durable than others.Are run flat tyres more expensive? Yes, run flat tyres do tend to be more expensive than regular tyres. Despite the higher price point, run flats are still very popular thanks to the added safety they provide.Airless tyres are designed to last longer than their air-filled counterparts. On average, they can last between 50,000 to 100,000 miles, depending on driving conditions and maintenance. This longevity makes them a cost-effective option in the long run.
What vehicles use airless tires?
Flatless tires offer several advantages over traditional tires and are compatible with a wide range of machines such as Commercial Mowers, Skid Steer Loaders (SSL) and other light construction equipment, Truck Mounted Forklifts (TMF), ATVs and UTVs, Golf and Utility Carts, and various military applications. Companies like BMW and others used run-flat tires across their entire model lineup. Most carmakers are now moving away from run-flat tires, as their supposed benefits don’t outweigh the negatives. A run-flat tire allows you to travel up to 50 miles without air pressure to reach a repair facility.Run flat tyres are OEM equipment on many new cars and they’re an important safety feature. But they can give a stiff and bumpy ride, they’re more expensive than conventional tyres and they can’t be repaired meaning you will have to replace them after a puncture.It is advised that you do inform your insurer if you decide to switch from run flats to regular tyres. This is because the change is classed as a material change to the car. A car that is equipped with run flats as standard has likely been designed to be used with run flat tyres.
