HEY. WHAT IS THE BIGGEST TIRE I CAN SAFELY PUT ON MY 07 OUTLANDER 400. I RIDE ON A LOT OF ROCK AND THE STOCK TIRES ARE JUST NOT GOING TO CUT IT. I NEED MORE SIDWALL AS I ALREADY BENT UP A RIM. ALSO I WOULD LIKE TO GET SOME STIFFER SPRINGS CAUSE ON SOME MODERATE SPEED WHOOPS IN THE TRAILS I BOTTOM OUT, ARE THEIR ANY AFTERMARKET SPINGS I CAN GET THAT ARE STRONGER TO HELP PREVENT HITTING FRAME ON LANDINGS? I AM A PRETTY BIG GUY AND STOCK SPINGS ARE A LITTLE WEAK TO HOLD MY BUTT UP. ANY HELP WOULD BE GREAT, PLEASE GIVE ME WEBSITES IF POSSIBLE. THANKS.
