So I have a 2004 Suzuki Z250. The stock rear tires are 20x10x9. I did a lot of research when I was shopping for tires and went with the ITP Mud Lites in 22x11x9. A bunch of people I talked too including some ATV stores said that going from a 10 to 11 in width would work just fine. So anyway I get the tires and mount them on my rims. within 2 days one of the rear tires is flat and off the bead. Now its about every week one of both of the rear tires comes off the bead and its getting very annoying. It seems like the tires are just too big for the wheels. So what are my options???? buy bigger wheels to fit these tires??? or should they work just fine like I was told??? Thanks guys

 

I would say your beads aren't seating right on the stock rims.

The tires are ITP, so a set of ITP rims should seat up just fine. Nice thing about the ITP rims, is that they are wider and have a greater offset than stock. That will make the quad several inches wider for a nice increase in stability. Do the fronts too.
