i'm currently running 19in Saleen Heritages and wanting to switch out to TSW's. i plan to keep my tires as they are nearly new and sell the wheels alone. do you think my 275 rear tires would fit a 9.5 inch wheel ok? my current rear wheels are 10's. also, will the offset fill my wheel wells or will i need a spacer to accomplish this? i ask because i'm thinking about the TSW's and the widest they come is in 9.5 not 10 wide.
