Kumho Tire comparisons...

Well, i have the 712's so i can give you my opinion

First off, excellent rain tire. When i am driving normally, it's a very confidend tire to be on. Of course it is a Mustang so you can still spin tires if you aren't careful.

I drive my car hard. I am more of a handling/braking type person. I'm always turning hard and braking hard and accelerating hard. Very good wear for what i put it through. Actualy very little at all. Also, very quiet tire when you spin tires! As for launching at the track, it's doable but it doesn't offer great off-the-line traction unless you are really paying attention. The hard thing is you need to feel when you are spinning tires because you will never hear it. If you plan on drag racing a lot, not a good tire to have out back. I have done it and pulled 2.1's 2.2's, but don't expect to pull hard off the line. For handling, it's pretty damn good. I've pushed them hard through turns and have yet to hit the limit. They stick very well WHEN WARM. When i say that, i mean after 10 mins of so of driving. WHen the temp is under 10 degrees, they get very hard and you can spin them at 60...but since you are in cali, you don't need to worry about that. They just perform better with a little heat. On a hot summer day, they stick like glue. But For $100 a tire for 235/45/17's, it's an awesome cheapo tire.
