ok i have douglas rims with 21/11/9 tires but i seen these tires i like and dont know if they will fit they are 25/12/9 but they are really wide and i dont know if they will fit im thinking the side wall will bend in to allow them too but not sure also the tires are knobbys i think but are really wide

 

They should fit.

 

Why do you want 25s?

 

im not sure now but i want to higher the quad a lil the back skid plate always bottoms out and gets me stuck i cant even go up some short steep hills cause it bottoms out
