My Avensis is now nearly seven years old but has done only 40,700 miles, completely trouble-free. I therefore plan to continue running it until it starts giving problems. One pair of tyres will soon need replacing. The current tyres are Michelin Pilot Primacy 205/55 R16. Given your comments about the expected lifespan of modern cars, should I pay the premium for new Michelin Primacy 3s, or should I consider a cheaper brand? If the latter, which would you recommend?
