Tyre Pressure Monitoring

How can we safeguard the safety of our road car or race car tyre pressures?

Introduction

The reader should note that some of the information provided in this article is

With the drive to reduce failures and their associated costs, tyre pressure monitoring

systems (TPMS) are a very important part of managing of a racecar programme.

There are two primary benefits for the system, in no particular order

• Performance analysis – data enabling the improvement of tyre use

• Safety – data giving a warning before catastrophic failure

From their inception, such systems have historically been fitted to cars running in

series such as F1, Champcar, IRL and Le Mans Series but there are systems on the

market that bring the price low enough for teams to consider it in championships

where they are allowed, for example in GTs and Touring Cars, and closed wheel car

endurance racing which put considerable loads on tyres if these are of a hard

compound and expected to last for many laps.
