From reading the forum/manual etc, it would seem the original tyres for the 240z were 175/80/R14. My car has minilite copies (JBW alloys) on, fitted with 195/55R15's (I realise the speedo will overhead slightly). I really like the look of the wheel and the tyres but although the car seems to handle well in the dry, I don't get any feel or confidence in the wet. Now it's difficult to compare because I haven't driven any other 240z's. The previous owner fitted budget tyres (Hifly) which may be part of the problem. Any advice on improving the wet grip? Many thanks
