I have 26 Mudlites and they work great. I did about 30 miles of GA red clay trail riding and was pleasently surprised by the ride. I did a good but of mudding with no trouble except when I set in on the frame.
I believe 27's would fit by they would be tight on the rears.. Worst case scenario, you could trim the fenders lightly.
