I love my Kumho 712's. Sticky, average road noise, good treadlife, good in the wet and most importantly, no problems whatsoever.
over the years I've had Yoko Avid H4's, (blah!!! the words high performance and all season are a really bad combination) and Dunlop SP fm901's and they were really good, sticky tires, just like the Kumho's.
I'd say give your wallet a break and get the Kumho's, unless you're auto-x'ing. Besides, having Kumho's keeps my urge to get stickers/decals in check because I don't want non car people (morons) commenting or asking me where the cum hoe is every time I stop for gas.....
Is this thing on????
