if you don't fix your cambers...your tyres will last only half its lifetime. This is because like what ckkean says - "the tyre will eat one side" which also means much less grip in dry or wet. The other side won't "touch" at all and it will be wasted.

The previous owner of my car had camber problems and although "one side" is new, the "other side" was not safe to drive especially if I'm going outstation.

wow...you guys change camber on your own? Cool...
