Ok, stupid question but I need to know.
Would it be possible to put 26 inch wheels with 1.75 tyres in a PX London road.
The circumference is 82 inches - that's only a tad off 700c with 25.
650b conversions are quite popular for 700c racers.
seems like a similar idea. Only issue will be BB drop. link below will help you with what to measure & calculate; obviously 26" (559) is a bit smaller than 650b (584)

its radius you need to concern your self with
possible? yes
whether it achieves your desired outcome in terms of geometry/capability/handling is another matter entirely.
As above 650B conversions to older 700c and 27inch bikes are not uncommon, and vice versa. I've also seen a few 650b to 26 inch conversions for various reasons. It's made a lot simpler for you since the LR uses discs so you don't need to worry about brake reach issues.
They key question is what are you trying to achieve?
Twitchy steering and scuffed pedals await. Worth a shot though.

I would imagine it is for the ability to have 1.75 tyres which may be too tall to fit in the frame if mounted to a 700c rim?
And given that the overall diameter would be very close then there would be no BB height changes (and believe it or not if the diameter is the same then so is the circumference)
And twitchy steering would never be a factor as fork angles are not changing

I have a feeling that the two might be related

26" with 1.75" Land Cruisers in a Kaffenback no issues for me. Strong wheels with comfy tyres and slightly more mudguard room.

If that were the case then 650B x42 would be a better option as closer to say 700c x 32-35 (which should fit on a LR?), but it might be that the OP has a pair of 26 inch wheels hanging around.
You can go with whatever combination you want really, some will have bigger compromises than others, but you'd probably get used to it regardless so it really does come down to what OP is trying to do, if it's just use spare pair of wheels then crack on, if it's something more concrete like wanting to run slightly bigger tyres and maintain guard clearance then 650B might be a better option.
