Living in central Alabama, I needed a tire capable of handling a little bit of anything. We get plenty of rain, and the occasional dusting of snow. However, I didn't want to totally compromise dry handling characteristics. This tire fit that bill quite well.
For pure dry grip levels, it's an all-season. Don't expect sports car levels of grip. However, it handles mild spirited driving just fine (even did an autocross or two on these). It doesn't make too much noise either. Treadlife and wear is nice, and appear that these will last most drivers well.
In the wet, they are great. We get some heavy downpours here, and I've always had full confidence hitting even large puddles on the highway at reasonable speeds. Wet traction is well maintained, and very respectable.
What little bit of snow we get (as well as the bit I've experienced with these during my travels out of state) was handled well by these tires. Obviously not a dedicated snow tire, but in light snow, slush, and even patches of ice they remained a solid choice.
If you're looking for an all-around go to tire that you won't have to worry about what the weather will be, at a great price, you won't be disappointed with the Kumho Ecsta 4X!
