best size and kind of tire on rhino

I run 26X12 Reptiles on ITP bead locks.  they are a little heavy but seem to work well in most conditions.

Those are real nice, I would also say if your replacing,maybe try a tire designed for a sidexside.

I ran Mudlite XLs on my 450.  THey wore very quickly.  Hit hardtop for 3 miles and you could see the wear.  Ride with a guy who runs 28" zillas on a rzr and he loves them.  From what he said, they wear better and are less prone to flats than the mudlites.  Last time we rode together, he ran very hard and I didn't see a bunch of plugs in his tires, so I believe what he said.  All things considered, they sound like a good choice for a light weight affordable mud tire.
