The self-study course, which began in September, is managed by the Retread Manufacturers Association (RMA) and is targeted for retread operatives.
It then culminates in a final exam, which is then ratified by the City & Guilds of London Institute.
Bridgestone’s technical manager Gary Powell said: “This world renowned examination body provides an invaluable qualification for retreaders in all aspects of the retreading process.
“As retreading is an important element in Bridgestone’s Total Tyre Life strategy, it’s important that our field engineers have the qualifications to help support our equity and franchise Bandag networks.
“This qualification supports our field engineers in delivering a premium service to our retread customers, so I’d like to congratulate Kevin and Sean for their hard work.”
As if this wasn’t enough, Kevin also achieved the highest mark across the whole of the UK for 2015 when gaining his qualification.
This was an excellent personal achievement and for his services was awarded with the RMA trophy by Bulldog plant manager Dan Edwards.
