Nankang's have been around for a few years now, and have proved to be a very good cheap tyre. being a Taiwan product. they are value for money.
Another new comer is Nexen, with a good range. have a look at there MT's. i put a set on the Hilux, at $175 fitted they are cheap enough.. time will tell how good they are, so far, after 4 months the only fault is the road noise..
A lot more noisier than the Nankang's
