They are YOYO.....there is a lot of people that still run 11's though, b/c w/ 10's, your choices of tires go up, but so doesn't the width of the rear end. I run the ITP's on my rear, as do some other members. The choices are pretty limited for rims, ITP, Douglas, and a few others, but be sure to use washers on the rims btwn the rim and the lug nut if the rim isn't beveled in. Also, if you stick w/ 11" wheels, it may still be a good idea to take the mud scraper off, as some people have had problems w/ them getting a rock or whatnot caught in them and damaging the rim.
