WTB 2 used Hankook RS3 is 265/35/18 or other size to fit the backs on an 18x9 wheel

I lucked onto some used 225/40/18 Hankook RS3 tires so I am trying to see if I can find a couple of backs.

I've got my 285/35/18 RS3 backs but they are quite a bit taller and while they fit in the back I am wondering if there is too much of a mismatch in height (25.9" vs the stock tire at 25.3" where the fronts are 25.1")

I also could run my 245/40/18 in the back but then I am giving up quite a bit of rubber and am worried I may get too much oversteer.

So does anyone have a pair of RS3 in 265/35/18 sitting around that you would like to get rid of?

Thanks

Steve
