I purchased my Mazda MX-5 1.6 in 2006 having read your in-depth review. At the time I recall that you recommended ensuring that the car came with Yokohama tyres, which I did. After 42,000 miles, the front tyres needed changing which, like many women I suspect, I left to my husband to deal with. I now have two Avon tyres fitted and all necessary wheel balancing performed. When driving for the first time the car's steering seemed very odd; incredibly light and the car seemed to not hold the road. The fun has gone from driving my lovely car. In fact it feels positively dangerous! Can two new tyres really make such a difference? Please help as I will be needing tyres for the back very soon as well!
