2. Making you cleaner, safer & saving you money!

3. Adding value to TPMS and lowering TCO
TPMS/RTPM solutions exist but with
technical and commercial challenges
SilentSensors’ solution is precise, low cost,
uses proven RFID & requires no maintenance
• Average error ≈ 1psi (cars) & 2psi (trucks)
• Texas Instruments guaranteed performance
• Rugged - wide temperature operating range
• No batteries, whole replacement units or
wheel or tire removals
• Less than £1 and 10g per tire
• Typically half or less than competing solutions
• Products for existing (retrofit) & new markets
• Existing market solution – easy retrofit cap
• New market solutions (built-in stem or patch)
• Patented for ≈ 75% of global market
• Inaccurate range of readings
• Wide margin of error
• Complicated maintenance typically
requiring wheel or tire removal
• Expensive (typically ≈ £50 a wheel)
• On-going battery requirements
• Typically confined to new vehicle market
• Limited retrofit potential

6. Food for thought
6
Ward's, est. 2010 1 billion vehicles globally;
Assuming tires under inflated by 10%;
Just in fuel and tire wear we could save the planet
£20 Billion pounds per annum
How far did we drive today with our
under inflated tires?
