I'd suggest tirerack.com or calling discount tire. Plenty of other tires will "fit" the wheel but many are not necessarily the correct speed and load rating for our heavy and fast jeeps.
That being said discount tire suggested the 295/40r20 Continental DWS all season. They are a little shorter than stock and I only run them in the winter but I think it's warrantied at 50,000 miles. The ride quality is vast improved but the sidewalls aren't as stiff so handling is affected. uploadfromtaptalk1429554124574.jpg
Size comparison. Stock up front and Continental in the back.
