Itp Atv Tires

My boyfriend is willing to buy my bike tires are 26x9x12 ITP 589 frint and rear and they are practically new and has a Suzuki King Quad 450 and I think the tire size is 25x10x12 25x8x12 and or something like that . My question is there a FIT AND HOW should I sell ?????? I did not buy them so I do not know how much we paid for them, I looked on ebay and they sell for about $ 450 for nine.

People I know who sell used goods, a figure of 50% of the cost of new ones at a fair price. If they are practically new, you could go up to 75%, but they are difficult to change and if you request it, he can just buy new?
