22bomb, are you only replacing the rear wheels and tires? How does it effect the handling? Thanks

 

22" tires are well suited for the DS, or any quad for that matter in these kinds of terrain, makes a whole world of difference. Defintely gear down going to the bigger tires. I run a 14 tooth in the front, makes for less clutching crawling thru rock fileds and such, and makes 2nd gear a heck of a good steep hillshooting gear. You will at least want to gear down to 15 tooth.

Increasing the rear tire size decreases caster angle in the front, and decreasing caster makes for a bit more sensetive steering and more twitch at higher speeds. To keep caster angle as close to stock as possible, 23" tires up front paired with the 22" in the rear is spot on. And the 23" tires are much easier to roll up over rocks and logs, and bridge across ruts.

25" tires will cause you problems with heelguard clearance, drastically alter caster angle making aftermarket adjustable a-arms necessary to get handling back under ideal control, and gear you up too high to compensate for with sprocket changes for the kind of terrain you are riding.

 

had the same exact problems with my first ds in the wisconsin mud. put on 22" razors in the rear and 23" matching in the front WOW!! what a difference. went down one tooth from stock on the front sprocket and have been running this combo ever sense. there are better purpose built mud tires but we run alot of logging roads and the over agressive tread slowed the top speed, but if you'r always in the slop might want to look into the mudder tires.

 

Thanks y'all, I appreciate everyones response. I will go with razr2's front and rear. I can't afford to lose too much speed, ya never know when ya might have to run from a bunch of Mexican logger "banditos".
