Keeping your tyres intact and your trucks rolling
OTR Tyres are leaders in solid foam filling which has been proven to extend tyre life, eliminate punctures and virtually eradicate unexpected tyre repairs. Though the compound is incredibly stable, it also provides flexibility and a comfortable ride for operators, which gives it the advantage over traditional solid rubber tyres.
Pumping a tube tyre fill with a solid foam compound removes the risk of punctures or ruptures. Carpenter’s world-leading Rely T-25 compound has proven itself time and again to reduce solid-shock and give drivers the same ride as pneumatic tyres. TyreFill WA has been solid filling tyres for use in mining, agriculture, civil construction for many years. It is one of the most highly adopted solid fill products in the world, and is available from TyreFill WA, part of OTR Tyres, based in Bellevue, WA.
The company has continued to innovate and has also developed a further technique that sets the ‘tyre pressure’ to OEM specs, ensuring safety standards.
The Science
Dual pumps are used to draw Part A and Part B from their individual containers and push them through a mixing screw before the combined liquid compound is forced through the valve of the tyre, which is mounted to the rim.
As the tyre fill compound enters the tyre, displaced air exits from a vent hole – just like bleeding a brake cylinder.
Once the tyre is filled with exactly the right volume of T-25 to give the required working pressure, it is allowed to set for 48-hours. From that point the tyre is flat-proofed and will be serviceable, without fail, until the tread is worn down to the witness marks. The two parts of the polymer compound must be stored at a specific temperature, in a special storage and mixing facility.
Benefits of solid filling
Solid filling tyres makes them impervious to nails, spikes, slag and rocks – in this respect, TyreFill WA’s solid fill is an investment that pays for itself. Unexpected tyre maintenance and replacement can often sideline equipment for many costly days.
By solid filling their tyres, mining operations save on expensive flat tyre repair and service charges, extend the service life of their tyres, eliminate interrupted work schedules, eliminate costly down time due to flats, and increase job productivity.
The substance not only reduces downtime in the machine, but also provides a quality working environment for the operator, by reducing vibrations and lowering risks associated with tyre blowouts. The process eliminates sudden loss of pressure, helps to handle overload situations, lowers the machine’s centre of gravity to reduce roll-over possibilities and improves traction.
Once the tyre is filled and fully cured the chances of tyre failures and blowouts are eliminated, improving on-site safety.
Tyres that are improperly inflated pneumatically, wear out sooner due to over or under-inflation.
Tyres filled with TyreFill WA’s solid fill are pressurised to manufacturer specifications and will stay that way throughout the tyre’s life.
Rely T-25 filled tyres can be run continually at 56kph or for up to two hours in an eight-hour period at 88kph.
