Question to the Department for Transport:

To ask the Secretary of State for Transport, on what date he plans to publish the conclusions to research into tyre-ageing on buses and coaches that he commissioned in December 2013.

My officials have consulted with experts from the British and the European tyre manufacturing industry who have provided consistent advice that chronological age is not an indicator of a tyre’s mechanical properties. Further research is currently being planned and the outcomes will be available next year.
