Yawar, do you remember which Hankook tire did the shopkeeper show you?
I've been using Hankook since a while now, it's been 1.5 years and they're shot. Sure they are soft and comfortable, but with my experience, the Hankooks I have tend to be noisy and squeaky at turns.
Any Hankook for 7500 will be an entry level tire and I won't recommend it, higher end Hankook tires are good though.
Yokohama Advan db on the other hand are much much better, had those on my Audi, really silent, run smooth and they last long as well unlike my Hankooks. Sure I take sharp corners at times but mostly my daily driving is at the expressway which means less corners, more speed, Yokohamas proved to be better for me.
If you really want a flawless tire, I'd say get the Dunlop SP Sport Fast Response, brilliant all-rounder. It has great dry grip, handles well at corners and performs well in wet as well, really puts all other variants to shame.
