TyrePal Solves Tyre Inflation Problems for HGV Freight Trailers
British firm TyrePal is launching a new tyre pressure monitoring system to help OEM trailer builders and trailer fleet operators tackle the problem of tyre blowouts on HGV freight trailers. The TyrePal trailer TPMS indicator consists of TyrePal sensors on each tyre and a robust indicator that can be mounted inside or outside the trailer. The indicator can operate independently of the truck to provide an immediate visual and audible alert when the sensors report rapid pressure loss, tyre
This leads to downtime and risks hazard to the driver and other road users. Apart from being very unsafe it will also increase fuel usage significantly."
The device operates on an internal battery - automatically recharged when power is available, either from the trailer supply or by connection to the trailer lights. When the trailer is not in use, the indicator goes into a sleep mode and automatically turns back on when there is any vibration, for example the opening of trailer
overheating, under-inflation or over-inflation.
"Due to the weight distribution and design of HGV trailers, especially double-decker trailers, if tyres pick up slow punctures, they often go unnoticed until it is too late," explains Peter Tilliotson, business development manager of TyrePal. "When the improperly inflated tyre is forced to work, it heats up and can cause blowouts.
doors. This means that it can remain on standby for up to ten weeks on a single charge.
The system can communicate with a TyrePal TeleTPMS module to provide complete on-line monitoring of the trailer from the fleet office, including full GPS tracking. This allows fleet managers to track their vehicles and monitor tyre pressure remotely.
of 3 metres. The new tyre combination overcomes the issues that often make optimising such trailers difficult if not impossible. The new KMAX D drive tyre reduces chassis deck height, lowering the fifth wheel by 5 to 6 centimetres to 91 centimetres, whilst the innovative KMAX S steer tyre lowers front axle height by approximately 2 to 3 centimetres. This further allows a sufficient gap to be maintained between the tractor and trailer during manoeuvring. This means that, within the maximum vehicle height of 4 metres, trailers with an internal height of 3 metres can be used, allowing volumes of more than 100 m3 for maximum transport efficiency. The tyres also permit axle loads of 8 and 11.6 tonnes respectively and is an alternative for
technologies. These include tuning the width of the KMAX S steer tyre’s shoulder ribs along with the geometry and sequence of the sipes. A 6-rib design has been adopted and the IntelliMax Ribs (circumferential ribs that link laterally) have been specifically adapted. Specific optimisation was also carried out on the V-shape tread design of the KMAX D drive tyres. Both steer and drive tyres feature Interlaced Strip Technology in their construction. Interlaced Strip Technology is patented by Goodyear and is an innovative belt reinforcement in the crown area of the tyre. This allows the tyre to carry more load as well as giving a better wear profile for increased mileage potential.
As a leader in innovation in the tyre industry, Goodyear has developed
Goodyear Introduces KMAX Low Profile Truck Tyres
Goodyear has announced the launch of a completely new industry size: the low profile Goodyear KMAX S steer tyre in the dimension 375/45R22.5. In addition, the company has further broadened its portfolio with another low profile tyre: the Goodyear KMAX D drive axle tyre in size 315/45R22.5. The new low profile truck tyres are the result of collaboration with leading truck maker DAF on their special Low Deck tractor and initially will be available only as OE fitment for the DAF CF and XF Low Deck tractors.
The size 375/45R22.5 is new to the industry and has been added by the European Tyre and Rim Technical Organisation (ETRTO) to the official list of sizes.
The two new Goodyear low profile truck tyres are an important step for the freight segment, where improvements in ton per kilometre are continually pursued, while respecting the height limitation imposed on vehicles. In order to maximise load capacity of more than 100 m3, many fleets operate megatrailers with an internal height
355/50R22.5 steer tyres and 295/55R22.5 drive tyres. The new tyres will initially be supplied to DAF for original equipment fitment and soon after as replacements.
The combination of low aspect ratio with high load index made the development of these tyres a technological challenge. To do this, Goodyear employed a mixture of engineering methods and
many tyres that are unique to the company, which help fleets maximise their efficiency. In the case of the new Goodyear KMAX S and D tyres, they have helped DAF to realise a truck that achieves its demanding needs by meeting the requirements of the TelliSys Project, which enables trucks to carry containers with a 3- metre internal height within a 4- metre vehicle height.
