I have a 1984 Mondial cab, US version. It has 4 new rims and tires. But the spare is the original 31 year old metric tire which is cracking. The last two times I had to use it, I was worried it would burst on the way to the tire shop. I would like to buy a regular, thin wheel with same diameter as the others, use only as a spare. By being thin, I would have room in the front compartment for the car cover, tools, etc. There are threads talking about hub patterns, offset, etc, but no cross reference to similar vehicles. What vehicles have a similar wheel hub pattern? Volvo looks similar. Again, only as a spare to drive a few miles to fix a flat.
