Having signed David Coulthard as its brand ambassador for ultra-high performance tyres a year ago, Cooper Tire has extended its relationship with the Scottish motorsport dynasty. Coulthard’s nephew, Murray Coulthard will complete the rest of his Scottish Tarmac Rally Championship (STRC) season on Avon Tyres. Murray drives a 1984 Vauxhall Nova and fit Avon ZZR rubber for the first time at the Solway Coast Rally, winning his class first time out. He will now switch to Avon Tyres for the remainder of the season.
