May not be an option with the tiny boot of a GTV/Spider, but I carry a full size 16" alloy as a spare in my 156.
I got it straight after I had to use my skinny spare for a short trip (just from home to tyre dealer), from that experience I said there was no way I was going to use it again as they are totally useless (as I said, their only function is to stop that corner of the car dragging on the ground!).
You are also speed and distance limited with them.
