Tyre Pressure Monitoring Systems
Tyre Pressure Monitoring Systems
A tyre pressure monitoring system (TPMS) is an electronic tyre safety feature designed to monitor the air pressure inside pneumatic tyres on vehicles. From November 2012, all new passenger vehicles must be equipped with a TPM system as a standard feature.
There are two different types of TPMS - Direct and Indirect
Direct TPMS (dTPMS)
Employs specific pressure sensors fitted internally to each road wheel.
Each sensor measures the tyre pressure and transmits the reading via independent battery powered radio transmission to the vehicle's instrument panel or display monitor within the cabin.
The information is available real time and provides the driver with exact details of which tyre is at fault and the speed at which the deflation is occurring. The systems are programmed with upper and lower pressure thresholds to trigger both audible and visual alerts where an issue is occurring and are generally considered the safest and most beneficial form of pressure monitoring.
Indirect TPMS (iTPMS)
These systems do not use pressure sensors to give actual pressure reading data but utilize a vehicle's ABS (Anti-lock Braking System) or ESC (Electronic Stability Control) to measure rotational speeds of individual wheels and tyres.
As a tyre deflates, its overall diameter will decrease and individual wheel speed sensors detect and report the event to the driver.
While iTPMS do not have additional hardware or spare parts requiring service or batteries and are regarded as very easy to handle, they are susceptible to influences caused by different tyre patterns, road surfaces and driving styles.
iTPMS systems will not generally detect a very gradual loss of pressure as the vehicle constantly relearns reference parameters over the course of 20 to 60 minutes of driving. These systems are generally reset manually by the driver each time pressure is adjusted.
Benefits of TPM Systems
The performance and behaviour of any pneumatic tyre is directly related to its inflation pressure. Stability, braking and wet weather handling are key factors affected when pressures deviate from those specified by the manufacturer. Tyres will leak air naturally - even when new and properly mounted.
Fuel efficiency and tyre wear are severely affected by tyre pressure and it is commonly understood that for every 10% of under-inflation, there will be a 2% reduction in fuel economy! Big numbers with the current price of fuel!
For safety, correct tyre pressures add greater overall vehicle stability, handling and braking efficiency - protecting not just the driver and passengers but other road users too.
Ideal Applications for Aftermarket Direct TPMS
Hometyre supply and fit a range of aftermarket DIRECT TPM Systems for all types of vehicles. Ideal applications include:
With absolutely no direct view of a caravans tyres or any feedback during a blowout or puncture, quite often the consequence of a tyre failure on a caravan can be catastrophic. From the damage caused by a flailing tyre to the underside of the vehicle - to worst case scenario - losing the tyre altogether and having the caravan over turn, a TPM system would immediately alert the driver of a problem and allow him to take necessary action. This could be coupled with TYRON bands for total protection.
As the majority of motorhomes lay idle for many months of the year and are often the first or second largest investment for their owners, a tyre failure is not only many times more likely than on a regularly used passenger car, but can cause untold damage to a vehicle. With such long wheel bases, a rear puncture could often go unnoticed until the tyre has worked itself clear off the wheel - leaving the vehicle almost uncontrollable.
Towed Micro-Cars and Trailers.
Small cars towed behind a motorhome - and trailers, are often towed completely blind but are equally susceptible to failure from punctures and blow outs. The results of which can often be catastrophic for both the car and the towing vehicle.
An early warning system in the form of TPMs will provide drivers with instant data an alerts in the event of tyre issues and could save thousands of pounds of damage.
