Dan,
I had been trying to find the wheel spec so thanks for the 10.5" which is 267mm and makes the 265 tyre an even more curious fitment.
I'll do some measuring when car is up in the air at Centre Gravity on May 3 en route to Donnington Classic. I had 11" wheels (ET55 wheel but effective ET48 with 7mm spacer) fitted with 295 tyres on my 3.8L 981 Cayman so 275 should not be too much of a "stretch" particularly as inner wheel rim (not tyre) clearance was the issue.
