For people insisting on a 'Classic' tyre but not wanting to pay silly money for them, there's always the Dimax Classic from Radar Tyres.
https://radar-reifen.de/en/patterns/dimax-classic/The Radar Dimax Classic is available in 175/70 R15 86H which I suspect would be ideal for a 4/4.

Or even a 205/70 R15 96V TL for just £60 a tyre which I suspect will just fit my 6" rims?

I have no experience of Radar tyres so I can't say if they're any good, all I've been able to find out about them is they are designed and manufactured in Singapore by Omni United.
https://www.omni-united.com/As with all 'Classic' tyres you are walking away from decades of tread development, saying that if people must have a 'Classic' tyre the Dimax Classic from Radar Tyres is very well priced and especially when compared with all the other so called 'Classic' tyres which are ridiculously expensive for what they are if you ask me.
