What i need can do to match all tires in the same size?
For Polaris Scrambler 500HO 4X4 2004

 

the ratio needs to be the same as OEM for the 4x4 to work properly.

 

You can go bigger but need to keep the 1" front to rear size difference the same. I put 25's on the front and 24's on the back and it rode like crap. I was running ITP mud lites in the stock size and i could go 90% of the places that the big boy Utes would go. The only problem is getting high centered. The smaller diam tire helps wheel speed getting out of gooey mud.
