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 toLower Co2 Emission – Environment -SocietyLower Consumption of Fuel and Materials used in tyres per Ton KM – Lower out flow of Foreign Exchange on Import of Crude - GovernmentLower 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

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………?

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 CertificationFrequent Calibration – Petrol Pumps &

FittersEnable driver to know loss of pressure on

real time basis for corrective action by

TYRE PRESSURE MEASUREMENT SYSTEM

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

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
