Wat size Tires fit the stock 250ex rims

 

Rear-Stock rims are 9X8". So, you want 20X11-9. You will probably want to run the Standard Holeshots (4-ply), because they are lighter and the little 250 can turn them easier. But, out here in the desert I run XC's, which are 6-ply. The stock rims are a bit narrow, and give the tire kind of a rounded profile, which I personally don't like, so I use the wider ITP t-9 9X9" rims.

Front-Stock rims are 10X5". You can run the Standards (2-ply) 21X7-10, but they will make your stearing pretty quick! I run the (4-ply) 22X7-10 XC's.

 

The XCR - 03s are good tires. I use them in the GNCCs and I have had no problem. They are lighter than the XCs, and they are narrower too. Any tire where the last number in the size is a 9 will fit the rims.
