Bridgestone’s ‘We’ve been everywhere’ Road Trip prize giving

Bridgestone’s ‘I’ve been everywhere’ Road Trip Flogging tyres isn’t the easiest job in the world; we all need them – at intervals far too regular than we’d like – but buyers tend to fall in to two camps – those who know a brand and ask for it by name, and those that have put on their car whatever the man at Kwik Fit is pushing this week. So ‘Brand Awareness’ is the name of the game (a game that can backfire – just ask Pirelli what’s going on in F1) and the more potential buyers a tyre brand can lodge its name in the brain of, the better. Which is why Bridgestone are running their We’ve been everywhere interactive campaign which very cleverly plots the escape of one man from office drudgery and showcases his journey out in to the proper world, all to a soundtrack of Johnny Cash’s ‘I’ve been everywhere’.
