I have an extra set of stock 17"s, I was wondering if these tires would fit they are Hoosier slicks 245 40 17 height 24.5 / width 10.0 / the guy said that they have 80 percent tire left and he is selling them to me for $180 the pair. Do you all think that's a good deal? From the pics of the tires u can still see the thread like two lines on each tire.
