Temp spare for 19"

[marsdalebear]

I have a 2016 S205 on 19" wheels. I am trying to source a temp spare but cannot find anything of the correct rolling diameter. Has anybody found a solution to this problem?

17 18 or 19 do the job. Just the tyre needs to be the right size.

Yes, that is what I am having a problem with. There seems to be no combination of wheel/tyre that matches the rolling diameter of the 19s with 255/35 and 225/40.

My dad's Jaguar XF with 245/40/19 uses a Pirelli T135/80R18 104M, USO Temporno.

If you throw that onto a tires size calculator it's .8% different in circumference. If you throw your 225/40/19 on the calculator the diff. is only 1.6%. I'd call that a pretty good match.
