Advice please:

Use Case

About 30% gravel, 70% tar. Never 4x4 real Jors Malan kinda 4x4, regardles. Once or twice two stretches of deep sand Groenriviermond - Hondeklipbaai. No typical overlander camelbacking, just light loads for two kreukeltieners sightseeing. Perhaps once Nossob to Garaghab. Tyre size 275/50R20.
Car will hardly ever go above 100km/h, even on highways.

Information needed

Is it really, really, necessary to invest R160k in 265/65R18 wheels, or should the 20" be okay for this use case?

Nope, not yet. I still cannot find it in me to EFT almost 4bar to buy a car. Especially as it has almost R500k worth of "legend 45" and Schöckl cosmetics, about the price of a 5-dr Jimny in bits & pieces that won't improve the drive. I am used to managing huge budgets, in both cash and digitally, and I am not stingy, but very rational. I typically don't think with my heart. And I saw a 1967 230S Heckflosse for about R400k......direkteurskoets indeed.

Not easy to decide .....

I can buy a row of houses in the Karoo for 4 bar. But one cannot drive a house over a dune!

In that Case I suggest, "hou verby Meneer" , with respect. Geländewagen ,I don't think are for the rational.

If that's your pace you could buy an old Landy or Hilux 4Y or ML for the price of the 18" wheels:confused:

I won't ever buy that japcrap thang again, once bitten, twice shy. But was contemplating this at the price of 4, not even 5 tyres! I love your logic, very practical.

Interesting how people experience things differently. Many South Africans say that one cannot air down 20" tyres at all, but others report having travelled up the dunes of Namibia, and the Skeleton Coast, after having deflated to 1.24 bar without ill result. Several American 4x4 forums report the same, but most Down Under absolutely insist one should be using high profile 33 or 35" rubber.

Time and own experience will eventually tell. In all our years of overlanding in regular sedans, we never got stuck, never had a flat tyre, and we also never overloaded. I often frown in the mall parking lots when I see these Mad Max rigs that looke like the School of Engineers teamed up with the Logistics guys for maneuvers. When I travel abroad, I only take hand luggage. My suspicions are that it's vehicle load, speed and driving style that shred the rubber.

But how or why should I know.....
