I've heard the MX rival the S03 in pure performance, get those!

I already have the Kumho Supra 712's. I have no problem with them, and have no problem buying them again. I am looking for a good all season tire. I drive all the time, probably 30,000+ miles a year. I figured I would keep it in the Kumho family, but I wasn't sure which tire handled, gripped, or performed best in the rain?

By "all-season" we mean that a tire can handle snow. Neither of these two Kumho tires can handle snow (they are summer tires), so I hope you don't encounter any snow and really cold temps.

The MX will have more grip and faster steering response at the expense of shorter treadlife and maybe somewhat noisier ride (that was the observation of some reporters when they tested it against tires like Bridgestone S-03 and Michelin Pilot Sport). But, the slight noise issue aside, apparently it's as good of a performer as those two tires against which it is competing. And definitely more performance than 712.

By the way, I love the tread design of MX much better than 712.

MXs are supposed to be comprable to S03s.
