Ok my above suggestion is probbably a little silly.
Proper tyre choice gets a little more complicated.
The way i look at it is
1. What exactly do you want the tyre for.
2. How many k's do you do P/A
for me tyer choice has become extreemly important.
for instance. Road Tyre compounds start to go off after 2-3 years
so i look at how many k's i do in that time frame. I attemt to choose a tyre compound which will last me around 1.5-2 years.
if you do 40k km in 1 year forgett the Falken RT 615's they'll probably only last you for 6mths or so.
if yo do 10k km per year......perfect. even better if you like the odd raceday thrown in.
also be wary what climate you drive in......I'd personnaly hate to drive on The RT 615's in a daily situation down in Melbourne. They need warming up. City traffic.......the'll only be marginally better than the Yoko A539's or C drives as far as grip goes. Out on the country road....in the twisties....no problem.
Sydney in winter makes them reasonably hard work in peak hr traffic....they still need warming up there too in winter.
so an apropriate tyre for the type of driving you do....is slightly different for everyone.
so now tell us what you really need.
