We lifted the tailgate and the spare-wheel-well lid and to our horror we were greeted, not by a shiny spare wheel and tyre, but by a Bose woofer, neatly shaped to fit the well space! We were testing a Porsche Cayenne 4WD on graded forest tracks just out of Lithgow, NSW, when one of its expensive tyres went ‘pop’. No problem, we thought, we’ll just fit the spare and head back to Sydney, where it can be repaired. Run-flat tyres and emergency spare tyres have no place in the Australian market, especially for people who want use their 4WDs for trips more than 100km away from service back-up.
