Which would be better, 20 inch or 21 inch wheels for offroading?

Would there be any problems with going with the 21 inch wheels?

Neither is good.
The sidewalls are so short, damage/scratching of the rims is almost a certainty. A big tyre with a 16 inch centre like a Defender's is ideal, but they don't fit our cars. Get the smallest wheel that will fit. If that's not practical, go for the cheapest set of rims you can find and know they will get banged about. Also, Al rims are brittle and the lack of air & rubber between them and the terrain is asking for trouble. Steel rims get be hit with a hammer to return them to a 'reasonably' round state.

The big issue with 275/45R21 tyres (other than the lack of sidewall) is that there aren't any available which are remotely suitable for off-road use. You're stuck with the Goodyears which are clearly going to be of limited use anywhere near a field. Good thinking Land Rover!

Shame, because the Style 4s are possibly the least offensive wheel design.

I'm plus 1 on the go for the smallest possible with the biggest sidewall. The 20 tyres on my car survived our outing on the Plain, just. It isn't the rim that is the real problem, if you go off-roading you will scratch them whatever the size, but the sidewalls that are the most vulnerable. A lower profile tyre with any additional load, think ruts with a side slope, results in a very vulnerable sidewall. My L322 S/C on 20's wrecked three tyres on a single day with chunks out of the sidewall, the L322 on 19's had a couple of smaller marks and cuts after almost exactly the same route.

You need AT tyres with tougher sidewalls for regular forays and there aren't a lot of those about for 21" and 22" wheels (=zero)

Someone will correct me I am sure but I think the 20" tyres on the L405 are 55 profile against 50 for the equivalent L322 20" diameter.

Yes, the 20"s are a higher profile than before. 19" wheels would seem to be the way forward.

We discussed the relative wheel size for the L405 off-road on our Salisbury Plain trip, or at least Craig and I did. I thought it might be good to get hold of some 19" wheels from the USA cars but the clearance between those big calipers on the front is already very tight and we wondered how much damage could be done getting stones and flints stuck in-between rim and caliper. 2019 D5 HSE Lux SDV6 Indus

The 19" Style 1 wheels are available as an option over here, but they're expensive in comparison to the usual price of take-offs from new cars.

Looks like the USA gets 20" as standard for 2014 - how vain are HSE buyers on the Continent? Slim chance you might find some on a European eBay site if you can be bothered trawling. Perhaps 2011 Style 15s would fit (with a spacer if the offset is much different).

Whilst the offset on the 2011 wheels might be solved I just wonder if it is spoke deign and caliper clearance that would thwart that idea. Need someone with L405 and someone with a style 15 to try that out. 2019 D5 HSE Lux SDV6 Indus

Front discs on both are 380mm - are the calipers different?

Think that L405 has 8 pot non-Brembo calipers and L322 6-pot. 2019 D5 HSE Lux SDV6 Indus

Pretty certain they're 6-piston and Brembo (albeit not branded as such).

Internet search suggests you are right. Look bigger than previous. 2019 D5 HSE Lux SDV6 Indus

style 1 19 inch actually look the nicest IMO anyways
