The ringmaster

Considerable road-testing experience backed by a degree in engineering sees Sydney motoring journalist Jimmy Whitbourn grid up as Tyre Test data analyst, and author, for the third time in as many years. A former Wheels road test editor, Jimmy set off for the freelance wilds in 2013 and now runs Carhelper.com.au while also reviewing and writing for this fine publication and Whichcar.com.au, among others.
