i have an 00 magnum 325, and a 96 xpress both Polaris. i want new tires for the mag. how big can i go? want somethign to make it a bit biggerbut not too big. any info would be great.

Personally? I wouldn't go much bigger than 25.

26" on my Polaris 700 definitely make it luggier. And some tires run big...Bighorns are my favorite tire, bar none....and they run big. My 26" on my 800, are really 27".

I agree, no bigger than 25", and stay away from the big lugs with the bikes you have go with more of an all terrain type tire.
