I wud recommend BRIDGESTONE & Yokohama, Kumho are cheap and durable as well. I feel expensive ones are just expensive becoz of the brand name and might be the same quality as mentioned above. Kumho is korean.

Unless u are into driving at exteremely high speeds on highways every day, u dont really need those expensive ones. thats my opinion, others may differ, no offence to anyone, they might be having more knowledge abt this.
