I have an XE-S/C also. I thought it was the best bang for the buck. I mounted 265/75R16 Interco Trxus on it with the stock suspension and had no problems. They were $114 a piece at the time from 4 Wheel Parts web site. Mounting was another $100 for five tires. Which I took in trade for my stock tires that had 1100 miles on them, so I didn't pay anything for mounting or used tire disposal. You should get a spare at least in the same size if not the same tread. Running mismatched tires on the rear can ruin the LSD very quickly.

Edited to add: I blew 2 in one week (1 from trail damage and one being stupid) and replaced the set with the next size up. At the time I had 17K miles on them and only expected to get 25K miles out of them before replacing them. You should factor in the expected mileage into your budget to see if getting a more expensive tire that lasts longer is worth it to you. I love the traction I get out the Trxus, but I expect to go through a set every year with my current mileage. Since I got them 4 other guys in my club switched to them from stock or BFG AT's.
