As for height, I would stick with stock. If you change the size of your tires you will need to change your clutching, and or gearing, or you will probably be disappointed with the performance of your quad. Also, we've had about an inch of rain here the last couple of days and not sure I can accurately test the slide of my tires (although I'm going to ride the s#!t out of the mud!!!) but once it dries up around here I will test them if you haven't bought new skins yet.

 

i have mudlites on mine and it will slide but i run em at a slightly higher psi, they are great tires and they are cheaper than the stock ones .

 

get the maxxis irazr 20 ' rear and 21' front.they are the perfect tire for a scrambler if you ride it like a sport quad.They wear fast,the rubber is soft but they do pretty good in mud compared to regular razr.I had them on my 500 and i liked them alot.They are expensive and they wear fast but verry good tires.If you dont ride on pavement alot then they will last alot longer.
