Grouptyre has promoted Karl Naylor, formerly director of commercial operations, to managing director following the departure of Peter Harries.

Since Harries joined 14 months ago, the company has seen sales growth of over 15%.

Before joining Grouptyre as sales manager for national accounts in 2004, Naylor spent 10 years at Michelin.

He has held the post of vice chairman of the Tyre Wholesale Group of the NTDA since November 2007 and will now assume responsibility for implementing Grouptyre’s business development strategy, which is centred on adding value throughout the supply chain.
