255/35/18

Have any of you ran a 255/35/18 on the rear vs. the spec 265/35/18? The reason I ask is that my front 225/40/18 still have at least 80% tread left as where the rears are shot. The problem is they have discontinued this brand in the 265/35/18 but I can still get a 255/35/18 and I would like for the front tires to match the back. I have a 97 boxster to begin with so I know I'm already going against the porsche recommended size for that year, running an 18 inch wheel vs a 17. Any feedback would be much appreciated. The car is never tracked and normally only sees 3-4 k miles per year.
