When i get new tires im probally going to get some sur traks. There are 3 25 inch sizes, 25x8x12, 25x10x12, and 25x12x9. Will the 12x9 fit on the prairies stock rim? What tire width combination should i use? What are the advantages to having a wider tire on the back? The 8x12s should go on the front and the 12x9s on the back, if they fit. Is this a good combination?
thanks

 

25/12/9 , 9 is the rim size and it will certainly not fit on a 12 inch rim
