(As a certified non-expert) I understand all Griffs came as standard with 15” fronts, and 16” rears. Except the ones that didn’t of course (later cars), which were delivered with 16” all-round.
It’s a vehicle design that is more sensitive to wheel design than some others. Even though they are a small car, the 15”/16” split looks a little underwheeled to some (discerning) buyers/owners, yet others firmly advocate the retention of OEM sizing.
So hypothetically speaking, what hypothetically would YOU hypothetically do?

1. Non!

2. Early 15/16"

3. Early split-rim 15/16 option

4. Later Estoril 15/16

5. Even later Estoril 16” all round

6. Even later OZ split-rim 16” all round option
7. 17” all round “base” Cerbera rims

8. 17” Ford RS rims

9. 18” TVR Spiders (or other aftermarket 18” rimz). Spiders shown as example only

10. Arrrrgh waaah waaah waaaah etc
