i have a 2.7 Kenda Nevagal on the rear of my banshee, i just actually threw it on a couple days ago cause i got sick of pinch flatting my skinny lil 2.35. ummmm it's big for a 2.7 i had to move the dropouts all the way back on my banshee to fit the fat pig tire without rubs *frame is said to hold a 2.8* i'd say the tire is a 2.8 as there is no way in hell i could go up a size in tire width sorry i guess i'm not much help, you could always check and see if the bike shop would be nice and throw it on for ya to see if it'll work out
