RunFlat systems, also known as RunFlat inserts are bolted into wheel rim wells and support the tire when flat, absolute zero air, allowing the vehicle to continue driving safely for up to 60km following ballistic or terrain related tire damage in a cross-country circuit incorporating a limited number of ramps, steps, ditches wadi dry river crossing, corrugations deep loose sand patches broken shrubs. Resistant to bullet impact, and designed to fits every type of automobile, SUV or truck. POLYMET run flats are designed to allow continuing driving even if the tires of vehicle have been punctured.

“RUNFLAT TIRE INSERTS system” manufactured by POLYMET Industries LLC – RAK are bolted inside the inner center of tire rim, allows to have continued mobility of installed vehicles in emergencies, such as loss of air pressure. Run Flat inserts also known as RunFlat system are bolted into wheel rim wells and support the tire when flat, absolute zero air, allowing the vehicle to continue driving safely for up to 60km following ballistic or terrain-related tire damage in a cross-country circuit which can be incorporating a number of ramps, steps, ditches wadi, dry river crossing, corrugations, deep loose sand patches, with broken shrubs etc. Run flat tire inserts are highly resistant to bullet impact and are designed and manufactured to fits every automobile, SUV or truck, designed to allow continuing driving even if all the tires of the vehicle have been punctured due to any or combinations.

·         due to either a 'normal'  slow puncture

·         puncture due to metal object penetrations 

·         deteriorated – bad- old-  tires –  ply separation while running

·         ‘intended hostile deliberate act to handicap’ including a spike strip or bullet strike

In any or all of the above situations, when the vehicle is traveling at speed, “RUNFLAT TIRE INSERTS system” manufactured by POLYMET performs to maintain vehicle stability, and proper steering control, and assists the driver to steer vehicle and assets to safety, meeting minimum traffic speed without the vehicle being stranded or immobile saving lives and assets.Tires, under  “ Zero”  deflation, will form into bulging, cracking, and deform to dimensional instability leading to ovality or non-circularity of tires, which during emergencies as above can cause heavy pattering, vibrations, sparking fire due to heat build-up, serious damages to rims and even lives and assets, by vehicle losing steering control.

There are different systems available for single piece wheels suitable for all  majority of cars, SUV’s and tow trailers whereas for military applications or for  on and off-road for multiple piece demountable wheels systems are offered with  bead locking systems are offered for split rims.“RUNFLAT TIRE INSERTS system” offered are manufactured by POLYMET Industries LLC- RAK, in the United Arab Emirates,  a 20-plus year old,  proven, and trusted manufacturer of bearing systems for bridges, building, metros, and mono rail systems,  manufactured out of high heat resistance virgin polyurethane composite of European Origin undergone extensive testing in hills and deserts of UAE for the past one year.

How run flat insert system offered by POLYMET differ from others in polymer

POLYMET with over 20 years of rich experience in polymer science, chose to go with 100% virgin polyurethane elastomer is a flexible, resilient, and highly durable engineering plastic in comparison to other cheaper and recycled composites currently available in the market for RUN FLAT INSERTS, such as PA6 – known as polyamide, or combinations of  Nylon, and composites, which mostly consists of   cheap recycled materials. Polyurethane esters offer excellent abrasion resistance and high chemical and oil resistance,  suited ideally for immense load bearing capacity, rebounding  properties with low heat built up,  particularly proven in mining and aggregate screening industry etc  for decades.  Polyurethane esters due to its good balance of physical properties provides excellent damping solutions such as shock and vibration absorbers, characteristics and qualities to meet grueling specific requirements of run-flat inserts, where much human life depends on it under hostile conditions. So a special polyester combination was developed for POLYMET after repeated testing to meet the off-road off-course, harsh and hot desert conditions of the Middle East through a prominent lab facility in Europe for run flat inserts.

Run flat insert system - Tested and certified independently.

Run flat insert system offered by POLYMET were tested repeatedly in grueling desert track of RAK with rubbles, dry crossings, having a number of obstacles such as natural ramps, steps formed in a wadi, ditches as well as gravel tracks with corrugations and loose sand pits – real hostile desert conditions of temperature ranging from 30 C to 50 C in a Loaded Toyota Hilux, loaded above its GVW gross weight of the vehicle. Test Vehicle was diagonally fitted with POLYMET Run Flat inserts, with absolute “ZERO “ air, was driven through the grueling desert track of RAK with rubbles, dry crossings, having a number of obstacles such as natural ramps, steps formed in the wadi, ditches as well as gravel tracks with corrugations, covered a total distance of 69.14 km in 02:08:17 "none stop, attained an average speed of 32.3 Km/h meeting FINABEL agreement mandate  - 2.3.2 b) travel off-road cross country for 2 hours at a speed of approximately 30 km/hr without the tire leaving the wheel rim or shredding. The vehicle was stopped as it passed over 60 km at 30 km/h, as per the FINABEL benchmark, tires, run flat inserts and rims were still in drivable conditions.  The temperature of desert gravel was from 35° C at starting to 50°C by noon and run-flat inserts and tire temperate were in 35 °C to 80 °C . The full run was verified and witnessed by International acclaimed 3rd party inspectors. These test was performed on 24th June 2022 in harsh desrts of Ras Al Khaimah rockey desert.

POLYMET offer 2022 year MTC tested in Middle East desert conditions, for run flat inserts which is much more challenging and demanding than tar road test in cold conditions. Material Test Certificate (MTC) is available on request with purchases.

Where is run flat insert system offered by POLYMET manufactured?

POLYMET Industries LLC - RAK, a 20 plus year old,  proven and trusted manufacturing house of bearing system for bridges, building, metros, and mono rail system, for project in Middle East and other developed countries,  has taken up the challenges to manufacture Run Flat inserts for local armoury industries on request to manufacture  in UAE. Now customers can procure from the trusted POLYMET facility and avoid inferior quality, parallel imported and brand duplicated run flat inserts without proper authenticated test certificates and or branding on the product. Being manufactured locally, supply time also is reduced.

UAE’s leadership also supports the transformation of the industrial sector into a global manufacturing hub- even His Excellency Dr. Sultan Ahmed Al Jaber, Minister of Industry and Advanced Technology says and promotes this always.  Tested to finabel test run flat insert test made in UAE Dubai  runflat run flats  inserts insert punctured combat tire tyre military applications Meeting European Army FINABEL Agreement No. A.20.A (20.A.5) FINABEL Agreement Pneumatic punctured Combat Tyres defense and security sector defense  UAE when deflated security sector finabel test run flat test report  speed  off road  desert  gravel road  desert temperature deflated  middle east climate sand  burning desert test  real combact situation deflated punctured uae  dubai
