Wheel and tyre dimensions for TVR 3000M with wide arches?

[griffer500]

I want to calculate my new LSD, there for I need to know what kind of rubber I can put under the wide arches (Adrian Venn).
I want to use the car for historic rally’s and not a fan of big rims.

Any suggestions?

Wheel and tire combinations:
only street legal rims can be used and should be a historic match with the car.

So what kind of rims and tires where used in the seventies?
