 What we know so far  Who can contribute to Reduce Rolling Resistance  Tyre Industry’s Role  Pneumatic Tyre – Awareness Level  Effect of Tyre Inflation  Root Causes for incorrect Inflation  Proposed actions Emerging Trends in Regulations – Safety Summary

Lower Rolling Resistance of Tyre Leads to Lower Co2 Emission – Environment - Society Lower Consumption of Fuel and Materials used in tyres per Ton KM – Lower out flow of Foreign Exchange on Import of Crude - Government Lower operating cost for the End User

 Tyre Manufacturers  Vehicle Manufacturers  The Government – By Enacting Laws – Bharat 4 – Bharat….6…, Tyre Standards Labelling… Incentives to Industry  The End User & its Service Providers ( Dealers, Tyre Fitters, Mechanics……..)

Developing and Promoting Tyres which offer Lower Rolling Resistance Tyre TypeRelative Rating – Rolling Resistance Estimated Market Share (Truck Bus) Bias4 70 Radial Tube Type Radial Tubeless2 1.2 Low Profile Radial Tubeless 1 1.1

 Switch to Tyre Types having lower rolling resistance  Proper care & Maintenance of the tyres during Service

A Tensile Structure Casing Tension Element Air/N2 Compression Element In order to achieve optimum performance the compression element (Tyre Pressure) to be maintained according to the Service Condition

 Increased Rolling Resistance – Higher fuel consumption - Cost of Operation  Loss of New Tyre Life & Retread factor – Higher Cost of Tyres per Ton Km  Premature Failures – accidents, Loss of Revenue, Injuries – Fatalities ◦ Sample Scrap Pile analysis showed 5.3% tyres failing due to deflation with 88% Remaining tread depth. 4.6 % Loss of the total Tyre Cost

 From where we get to know the correct inflation pressure for our tyres? ◦ Markings on the Tyre ( BIS Requirement) ◦ Vehicle operators Manual ◦ Petrol Pumps Air Filling Point ◦ Tyre Fitters ◦ Tyre Manufacturers – If we have ever approached ◦ Web sites………?

Tyre SizePRLoad/Tyre Kgs when fitted Inflation Pressure kPa/PSI Single Dual / / R /120 11R22.5 T L / /80R22.5 T L / /80R22.5 has about 15 % higher Load capacity

F.A Load/ 2= Load/ tyre R.A Load/4= Load/ tyre

 Enough data has been published to demonstrate that tyres are not properly inflated  Very Little has been done to find out the root causes & offer remedy.  We need to know ◦ 1 Does the operators know the correct inflation for his tyres & application?

◦ 2 Does the operator has reliable means to check if the tyres are inflated to the desired pressure ? ◦ 3 Does the operator has means to know on real time basis the drop in tyre pressure to take corrective action? ◦ Answer to 1 & 2 could range from 15-80% ◦ But Answer to 3 is definitely NO for over 99% in India

 Customer Education drive to select proper Tyre Size based on the maximum Axle load and correct Inflation Pressure – Tyre Companies & Vehicle Manufacturers  Educate Dealers, Tyre Fitters( RMP), Vehicle Repair and alignment centers  Certification of Tyre Fitters ( RMP) by RSDC/ ATMA

Tyre Pressure Gauges - BIS Certification Frequent Calibration – Petrol Pumps & Fitters Enable driver to know loss of pressure on real time basis for corrective action by TYRE PRESSURE MEASUREMENT SYSTEM

 Tyre Pressure Sensors  Radio Frequency Receivers  Display

 Schrader Electronics in India is under the process of developing the TPMS for Indian Market  Lot of Work is being done on Intelligent Tyre by Foreign Tyre Manufacturers  Indian Tyre Industry along with O.E.M’s need to drive the development of TPMS for Commercial Vehicles with ◦ Existing players ◦ Technical Institutions – to Develop affordable & Reliable TPMS 

 Purpose – ◦ To make the customer aware of the tyre characteristics & enable him to make a informed choice. ◦ To improve the safty, Economics and Environmental efficiency of the Road Transport ◦ U. S.A ◦ Uniform Tyre Quality Grading ◦ Tread Wear ◦ Traction (g- force)CBA ◦ TemperatureC (85-100MPH) BA above 115MPH

 European Union – Nov  Fuel Eff. ( R. Res) G F E D C B A  Wet Grip G F E D C B A  External Rolling Noise  Above Future Limits Not acceptable  Future Limits  3dB below future Limits

 Promote Low Profile Tubeless Tyres in O.E & Convert existing Tube Type to Low Profile Tubeless Radials in the Replacement market  Educate Users, Dealers, on deciding the correct tyre size and Tyre Inflation pressure for the specific application.  Organize Training & Certification of the Tyre Fitters on recommending proper Tyre Inflation.

 Tyre Pressure Gauges to be brought under mandatory BIS certification  Tyre Industry Vehicle Manufacturers to promote TPMS with the help of existing players.  Vehicle manufacturers, Tyre manufacturers & the Technical Institutions to collaborate in developing products & Services which will help the end users to exploit the full potential of the product features
