I just returned from the dunes and had two incidents where I was left stranded with flat tires. I have a RZR S w/ 25 10x12 Extremes on ITP SS wheels on the rear. Was doing some heavy side hilling and popped the bead on the right rear. Finally got some air in it. Cleaned the bead & aired it back up. No problem. Went from the recommended 4lbs to 5 1/2lbs and gave it a shot the next day. Same thing happened on the left side. So, here's my question, are the Extremes just prone to this or should I consider beadlocks? I'll be replacing the tires after another trip or two to the dunes. Any recommendations on other tires that work as well as the Extremes but maybe with stiffer sidewalls that arn't so prone to pop the bead? Thanks in advance.

 

Beadlocks will definitely cure that issue.

 

Either bead locks or Tire Ballz. I think that's what they're called. Used by MX riders and GNCC guys to keep tires from derimming and going flat.
