I'm running 25 inch vamps the back of a 86 250 and it spins them no problems. I was out climbing hills the other day with it and I was able to spin them all the way up no problems

You can run as big of a tire as you want, if you want to do the mods to support them, 32's, 34's ,40's take your pick. Stock machine I wouldn't run anything bigger than 26's though.
