Ok here is a 275/40/17 Maxis RC-1, brand new, on a 17x10 wheel, it fits but that red plastic trim tool is 3mm thick and can't clear the gap. I estimate 2mm. I don't know the offset of this wheel but it is pretty tight in there, you could space it out a few mm and gain a little clearance...

Also these are Koni FSD struts, and while they look identical in dimension to OEM, there may be slight differences. Although they do look identical.

I've seen other boxster guys run 275/40/17 back and 255/40/17 front, if you can't get that 275 in there, which would be ideal for rotating tires...
