Tyre pressure effects driving performance
It’s widely known that tyre pressure effects driving performance. When tyres are underinflated, a car is more difficult to steer and slower to respond. There’s less feeling of connection with the road, and the reactions of rear tyres seem to lag behind the front tyres. At TyrePal, we are interested in the impact of tyre [...]
Should I choose TA22 or TD series?
TA22 TA22 is optimised as a safety alert system that will quickly give warnings when things are going wrong, with a clear indication of the nature of the problem and which tyre is affected. It’s a ‘set and forget’ system that sits quietly in the background unless it is needed. There’s no continuous display of [...]
Is TyrePal suitable for high speed applications?
Yes! Our sensors have been actively tested at speeds up to 300km/hr. TyrePal systems are frequently used for high performance cars such as Ferrari, Porsche and Aston Martin for track and race applications where high speeds are the norm.
Impact of tyre pressure on dual wheels
Mismatched tyre pressures are a real problem for dual wheels. The mismatch results in a change in diameter that makes the larger wheel drag the smaller one and the smaller wheel hold the larger one back. A difference of just 5 psi can change the diameter by as much as 8mm, resulting in the smaller [...]
International standard for TPMS
The international standard for tyre pressuer monitoring systems is ISO21750. The standard was written to cover direct and indirect systems, and TyrePal systems can operate as a tyre pressure warning system well within the requirements as defined in this International Standard. ISO standard requirements To comply with the standard, a system should give an alert [...]
Can I get extra sensors for another vehicle?
This depends on the system. You could for TA22 system, if you are prepared to ignore the ‘no-signal’ error message, but generally you can’t for other systems. TD1000, TD1200 and TD2200 are specific systems for four or six wheels and these will only recognise one set of sensors. If you want to use one of [...]
What alarm levels should I set?
Installed the sensors on my Renault Espace this afternoon and went for a 3 mile trip. I set the low tyre pressure a couple of psi below the Renault quoted cold normal figure and the upper a couple of psi above the quoted cold normal figure. As expected the max pressure was exceeded and the [...]
Performance tuning tyres
Whatever adjustments you make to suspension components, the objective of tyre tuning is to optimise the area of rubber in contact with the road – the contact patch of the tyres. That contact patch is not only affected by suspension components, but also by tyre pressure. Temperature effect When you drive, the friction between tyres [...]
How can I get the best accuracy from the system?
Display and alarm resolution for TD1000 is 0.5psi and sensors are guaranteed accurate to +-1psi This is appropriate for general road use and is well within the range specified in ISO21750, which is the international standard for safety warnings to be provided by Tyre Pressure Monitoring Systems. To get the best possible accuracy from the [...]
Managing tyre pressures
Effects of incorrect pressure Incorrectly inflated tyres reduce the contact area with the road, leading to: less grip increased braking distances poor cornering uneven tyre wear If tyres are under-inflated, they have greater rolling resistance, so they waste fuel and wear faster. Driving on soft tyres puts tremendous forces on the sidewall, both in supporting [...]
