I'm sorry to say, but Nexen are rubbish. They smoke a lot for skids, thats about it.
When I had my car lowerd very mildy, I didnt even get 10,000k out of the insides, maybe I should have rotated quicker, but common 10,000!
I can get okie Nankangs for $170 fitted 18/235
Those also suck in the wet though. Don't think there is such a thing as a decent tire under $500ea that is good alrounder.
