Kevlar Tires

Hello everyone. New to this forum, but have had this Gator for a while. It’s a 2004 4x2 and is used on a ranch here in the Texas Hill Country where mesquite thorns play the devil with keeping the tires inflated. I’ve used Slime in those tires for years but the tires are getting pretty worn now and it’s time for a new set. I’d like to get some Kevlar tires for it, but don’t see the correct sizes anywhere that I’ve looked. The rear tires are presently AT25x13-9 and the fronts are AT22.5x10.0-8.

Does anyone know where such tire sizes are available in Kevlar? Or, what alternative size wheels will fit and function well on this Gator with a different size Kevlar tire?

Many thanks for any help.
Bill
