[Roadsters] Space-saver spare for a Roadster

[RWM@RWMann.com]

The rim is indeed four-lug, a Topy 14x4.5, the OEM supplier, I believe, from a Datsun 260Z.

But I see the confusion I created, as it is actually a C78-14 space saver spare. 

Not sure where my brain came up with G78…

Today I put vehicle dollies under the rear wheels and saw that the right rear tire, which I aired up last September, has a split outer casing – which it didn't have in September. It is holding air, which is kind of amazing, but the damage is quite impressive. Increasing the pressure in an old and obviously brittle tire must have split the outer belt.
