I saw someone else posted about Continental ProContact ECOPlus
and was very happy with them. I looked them up on tirerack.com and they got really, really good reviews - but they were still #2 out of 24 based on some category that tirerack has. #1 was Hankook Optimo H727, which included some rave reviews from Jeep owners. The tires are about $40 cheaper per tire compared with the ProContact ECOPluses in my area, and there are a few "buy 3, get the 4th free" promotions in my area as well.
It seems like the obvious choice... but I've never heard of Hankook before. Does anyone have any experience with them?
