lift, tire size

ok, here it comes get ready,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, what do I need to do to run 30's skinnys on a 08 800 50"? sorry for "that" question. This is my wifes so there wont be any real playin going on. She wanted something to follow me around on (go around the holes) at the parks (and riding shotgun on the dirt roads dont sound bad eigther ). Guess she got tired of flipping over and getting wet from the neck down. Im thinking 30's because I feel like thats a tire size that can get you through, and over a few things that stockers cant. Im running 30's on my foreman and feel pretty good about them. Also, Im gonna run 2" spacers on all fours too.
Thanks!

Advise from experience , Don't do it , Just put a lift on it and stay with 26's.
I put 27's on my 800 S and i could tell i had lost power. tried it for 6 months , and went back
to 26 bighorns and never looked back...

I expected a little power loss but i didnt think it would be too bad. I got them on my foreman 500 and noticed a little loss but iv never had a problem with them. Wonder why a 800 would have problems, is it because there belt driven?

Everything with bigger tires than stock will loose power. if your ok with that , then your fine.
I don't ever like loosing power. also your foreman i am assuming is a four wheeler right?
An RZR weighs over twice as much....

lift will be better but you can go with skinny taller and not loose too much but you might need to do a clutch kit too
