The car is driven generally in the city, but many, many long trips (1000 Km+) have been a regular feature too. I drive quite hard on the highway and very carefully in the city. My primary need is for a tyre which can take a lot of beating (less punctures and bulges) and be low on wear and tear, be low on road noise (a little is acceptable) and have good drip/handling on dry as well as wet surfaces.
AR 20, Yoko Earth 1 (both symmetrical) are better for your requirements however for hard cornering you need to go for asymmetrical tyres.
I personally like the BS Turanza as it have been proven over a long time. Does anyone know the difference between the Turanza ER60 and the Turanza AR20?
Here is link. AR 20 are advanced version of ER60.

Any suggestions on this would be welcome.
Xm2 are best only if you are careful on potholes to avoid sidewall bulge, ironically they are designed by Michelin to withstand the pothole craters.!!
About C drives I don't have experience.
