So I need some new tires for my raptor 250. The stock size is 19-10-9. Is it possible to put 20-11-9 on stock wheels? can the width of the tire be changed without getting wider wheels?

 

I have spent a lot of time testing different tire size/gear combos for the raptor 250... hope this is some help. first and foremost; these tests were done with a 190lbs. rider, stage 3 modds. the stock 19s are set up good with the trans gearing and final drive 14/38. for mx i run ITP mxr6 18x10x8 with a 15/38... works great. a 14/36 works well also. it would be the difference in track length as to witch set up to use. if your running paddles i run Skat-Trak 20x10x8 6-blade gliders with 14/38, but 13/38 will pull in third good. you can not run aggresive paddles unless you got at least 30hp with the 250, and i think low to mid 20s is good and still reliable. for trail i run ITP 20x10x9, but it may hit the slip-on with aggressive riding, i found ITP mxr4 19s are great. a slightly modded engine will run 20s good...

 

awesome! thanks a lot
