The front tiered are 27x9 and the tears are 27x11. Is it possible to have 27x11 all the way around? Sorry if it's a newbie question but just wanted to see if possible. I need new tires so seeing what my options are. Thanks

Well, you can with another set of 8" wide rims like on the back but...they may rub on stuff on front and...they will kill your front end parts like tie rod ends, a-arm bushings and ball joints. I had 11's once on my Brute all the way around and it killed not only my arms and shoulders, but took out the a-arm bushings and stem bearing all in less then 300 miles. So..I highly recommend NOT doing that. A better option would be to get a set of 7" wide wheels all the way around...like some 5+2s, and get yourself a set of 10" wides for all. That's only an inch less in back...and one more in front. And you can rotate them...and if you get a spare it will fit anywhere.
