I have been looking to get some new tires for one of our Polaris Rangers, 900 XP. It currently has the factory tires, which I believe were Carlisle 489 AT.

As I look at some different websites, I have a hard time finding a big selection in the current sizes. The current tires are 25x10-12 up front and 25x11-12 in back. Is it OK to go to 26 inch tires? Seems to be many more to chose from if you go up in size. Any other suggestions for specific tires welcome.
