I've got a 99 450ES with stock tires on it, 25x8x12 for the front and 25x10x12 for the rear. I'm considering putting on 26x10x12 tires on the front and 26x12x12 on the rear. Would these tires fit the stock rims? Has anyone done this before?

 

Yeah, they'll fit.

 

Yes, On my 2000 Foreman ES, I have 27x10x12(front) and 27x12x12(rear) Vampires on stock rims.

 

Thanks for your answers, I've ordered a set tires, settled on the Titan 589's.

Now I've got 4 used stock tires (without rims) I don't have room for, is there any market to sell them? What's a fair price?

No punctures or tears, only about 300 miles on them so the tread is good yet.
