TYPES OF RUN-FLAT TYRES(RFT)

runflat tyres simply means tyres that ensure mobility of a vehicle even when the tyre has lost pressure or has a blowout,

here are some types of runflat tyres available depending on the use

1. Self-Sealing Tyres

Self-sealing tyres are engineered to repair most tread-area punctures instantly and permanently. These tyres have a reinforced, specialized tyre construction with an additional interior lining underneath the tread that is coated with a proprietary resin (puncture sealing material similar to what we use on our self-sealing fuel tanks) that can help seal punctures from common road hazards such as nails, screws, glass, or other debris with a diameter of 3/16″ or less.

As soon as the special lining is punctured and the object is removed, it immediately heals or seals itself and fills in the gap to stop an air leak and prevent loss of air pressure. For small perforations, most drivers won’t even be aware that they suffered a puncture since they will never lose air pressure or experience a mobility crisis. For unarmored vehicles or for typical consumer use, self-sealing tires can be a good option to prevent a loss of mobility from small road hazards.

2. Self-Supporting Tyres or Run Flat Tyres (RFTs)

Self-supporting tyres feature a stiffer reinforced internal construction, that is capable of briefly supporting the weight of a vehicle during a loss of air pressure in the the tyre.Self-supporting RFTs will typically allow passenger vehicles to travel between 30-50 miles depending on the weight of the vehicle, travel speed, road conditions, and other factors.

3. Auxiliary Supported Run-Flat Systems these Tyres are Coupled with Run-Flat Inserts or Inner Supporting Rings

auxiliary-supported runflat systems combine special, inner security inserts combined with OEM wheel assemblies and heavy-duty tires with a high-load index. With this mobility solution, the run-flat insert is fitted around the OEM wheel or rim between the rubber tire and metal wheel. In the event of a blowout or loss of pressure, the rubber tire will deflate normally, and the vehicle will drop down onto the inner runflat insert which will come in contact with the rubber tyre and support the vehicle, helping keep the tyre in place for an extended period of time and protecting the OEM rim from impact with the driving surface

4. Tactical “Military-Style” Wheels With Specialized Runflats and/or Beadlock Systems

While traditional runflat inserts are an excellent solution for many applications, they can pose a risk for clients driving in particularly harsh environments we tire/wheel clearance (air gap) is critical—in a scenario where runflat inserts come into contact with a large pothole or road hazard and the impact is transferred from the insert directly to the OEM wheel, the OEM wheel can crack or break depending on the force of the impact and the construction of the wheel
