Can you not get either of these sizes under your arches?

215/50 ZR16 90W 2G
225/50 ZR16 92W 2G


The sidewalls are stiff on R888s, to the point where you could go up a size in aspect ratio, and not notice any more flex/ lateral movement over a more 'conventional' tyre.

I used 195/50/15 R888s on my Pug 205 when a 195/45/15 would have been perhaps more ideal - as long as they fitted on the car I was determined to have them as the dry grip is awesome, and makes a compromise elsewhere well worth it.

Martin is the cheapest place I've found for the R888s too
