The RMA was established in 1938 and remains an active member of BIPAVER The RMA is a nationally recognised body that represents the interests of the independent UK Retread industry Scope of RMA membership: PROCESSING MEMBERS – Car/Van; Commercial Vehicle; Agricultural; Earthmover SUPPLIER GROUP – Raw materials ; Equipment ;Casings; Tools ; Repair materials LIAISON GROUP – Tyre Consultants ; New tyre manufacturers ; Trade associations We have a board of seven individuals representing a cross-section of membership RMA has representation with BSI - and is active within several other trade associations We have a very active City & Guilds program designed to encourage professionalism in our industry General Introduction

What is a Retread ? A Retread is a generic term for the re-engineering of selective worn tyres It is process that involves extending the life of a ‘tyre casing’ by assessing its integrity throughout the entire process This may involve the use of non destructive equipment such as Shearography ; Ultrasonics ; Pressure Testing ; etc Top – Capping A process in which the worn tread rubber is renewed, by application of a preformed and vulcanised tread Recapping A process in which the rubber is removed from the worn tread and over the shoulder and new rubber is then applied Remoulding A process in which rubber is removed from the tread shoulder and sidewall, new rubber is applied, extending from bead to bead There are three types:

The Market Place (the facts) It is estimated that there are approx. 5 million EU Commercial Retreads manufactured each yr. The UK manufactures approx. I million commercial vehicle Retreads each yr. NEW vs RETREAD Ratio: 1:1 - UK commercial vehicles are running on Retreaded tyres (Estimated) 70% + of your groceries are delivered on Retreads The environmental saving are staggering - extending the life of a worn tyre Average savings per truck tyre: 44 Kgs of rubber ; 68 litres of oil ; 182 Kg Co2 Tyre manufactures produce tyres for multiple lives and all have a Retread manufacturing facilities – Bridgestone – Michelin – Goodyear – Continental - Many commercial airlines operate using Retreaded tyres In Italy the government has specified that at least 20% of state owned vehicles must drive on Retreads Retreads can sometimes even out perform new tyre! By Law Retreads are manufactured in accordance with ECE 108/109 This regulation ensure that the quality and performance is on par with the quality expected from a new tyre They are tested to the same stringent performance criteria as new tyres.

Expelling the myths of Retreads ? Are Retreads safe - they blow out? They can only be used at slow speeds? Not good value – false economy ? Responsible for all that motorway debris? Not as good as a budget tyre? ‘Lets answer some of the above myths’ Maximise the mobility potential of worn tyres via PROFESSIONAL RETREADING

What to look for when choosing a quality Retread? Tyre markings: All Retreads should exhibit the ‘E mark’ E R The above approval mark shows that the retreading production unit concerned has been Approved (in this case E4 – Netherlands) under the approval number 109R thus meeting the requirements of this legal regulation The approval number must be on the same side of the ‘E’ marking usually place above or below as illustrated. Check you have the correct construction Check the service description is correct for the vehicle (load and speed capabilities) Check with your supplier the regarding correct application and operating pressures Check it has a brand name you trust Ask your Retread supply if they are members of the A sign of professional Retreading

Tyre Age / Ageing of tyres Nothing stay the same for ever!! The Rma recognises that the integrity of the tyre casing prior to retreading is absolutely vital The Age of a tyre is only one of many factors when considering a worn tyre for retreading Retreader may imposed internal specifications that consider the age of a casing although this is not a requirement of Reg.of ECE 108/109 A combination of skill, experience and complex non destructive equipment significantly reduces the risk of in service anomalies such as premature tyre failure The ‘Ageing of tyre casing’ is much more of a problem! During the course of tyres life it may be subject an enormous amount of use and abuse Rma members are encouraged to invest in non destructive equipment to check the casing integrity Poor tyre/vehicle management can severely affect the casing integrity - rendering the casing scrap – Best practice documents that emphasises good tyre management will maximise a customers investment
