I had a very nice experince with Nexen 2000 185/60-13. The tyres were excellent in all aspects but on last they got deshaped.
As they were equiped by previos owner of my car so i cant come to the coclusion that either there is flaw in tyre manufacturing or that is due to careleesnes in maintenance.
During my next tyre change i wana buy the stock tyre size which wasnt available in nexen so i go for Good year.
BTW i m not sure about their durability as the guys in tyre market passes comments that all Korean tyres has flaw of deshaping. These comments are from market guys & might be the wrong. So one he had used that tyre from brand new to its end (Whole tyre life) may comment better.
But i will say again that Grip, Drive, & Braking was awesome.
