My tow vehicle is an Isuzu MUX and I am thinking of changing my tyres to All Terrain (A/T) but am unsure if the spare tyre under body housing will accommodate an A/T tyre profile.
Be prepared for the increasing noise level of all terrain tyres as they get older. It is part of the reason I have stuffed my car full of acoustic insulation. Extremely quiet now.

Don't forget increase in fuel consumption. Noise = energy = +fuel. Energy has to come from somewhere.
Has anyone notice how much more fuel you burn when driving in the wet. Wet = more resistance.
Our fuel consumption increase by 5%. It is hard to say what percentage of the 5% increase was due to increased tyre width from 235 to 255mm vs all terrain tread on its own merit.
Unfortunately Land Rovers have what I call poodle rims so there is a limited range of tyres due to rim size, in Australia at least, as we only get a very limited range of tyres. Too smaller market.
Disclaimer, we went from 4 punctured tyres & 1 destroyed in one year with road tyres to zero punctured tyres the next year.
TPMS saved us the other 4 tyres after I learnt the lesson of a destroyed tyre situations in remote areas with TPMS.
As long as you stick to the same tread width I think you will only have a fuel inefficiency increase of about 2%. Maybe others have swapped road tyres for All Terrain tyres of the same dimensions & can comment with their recorded fuel efficiency data.

I was advised by a tyre company that even though you can repair a tyre using the repair kit, you should still have it professionally repaired as soon as possible. Your repair is from outside in, whereas their repair is from inside out and is more robust. You really only need to repair a tyre if you damage two or more tyres because if it is only one, you put the spare on, not repair the damaged tyre.
I happened to be in one of the large tyre chains & while waiting for my new set of tyres. They were repairing another customer's tyre in exactly the same process as a tyre kit, except that they used air tools to clean out the hole & an air tool to plug the tyre.
Which reminds me, since I have a high capacity air system onboard I should get the air tools. A lot easier doing the plugging with the hand tool.

Most of my punctures have been due to screws. Even in remote areas.
Once I had a rock snap off inside a tyre.
I plugged someone's tyre in a remote area with 4 plugs. They didn't have much option as their only spare was in worse shape. They just had to drive very slowly back to civilization.

My BFG A/T are definitely fatter and when new, taller than the standard H/T fitted at the factory even though the are the same size by description. That said they fit the under tray cradle easily enough. If you're up for new boots and your spare is aging then consider a five wheel rotation. If one of your existing tyres has life then it saves money in the short term to just do four. My first puncture (a massive chunk of rubber off the tread near the sidewall) was with a 4 yr old spare that never saw the road until I did a complete rotation. It managed about 600km ! The compounds were simply too hard from no use.
Hi Monty,
When I bought our 2019 D-Max, I asked the dealership to fit 16" wheels to it - I can only assume they swapped my LSU (17") wheels for the LSM's 16". The problem was the overall tyre diameter was smaller & my speedo was out. I drove with the voice saying "You are over the speed limit" to keep me on the straight & narrow. When the tyres wore out, I consulted the gurus on the Ozisuzu Forum as well as the tyre dealers here & fitted 265x70x16LT Bridgestone 697 ATs. The speedo is now correct & the spare fits in the well under the car.
A friend has a 2018 MUX & he has the same tyre in the 18" size - again with the correct overall diameter.
I noticed Mike H above suggested just buying 4 & keeping the spare as was - that is ok if you're hanging around cities but if you need the spare when you're remote, it's far better to have all the tyres the same.
I've been running AT tyres for about 30 years & not had any issues with them. Yes, some are slightly noisier, but they are more suited to the areas that I regularly travel in. I am very wary of tyres that have firming blocks on the edges of the tyres - when the tread wears down to them, water cannot escape out the side & you run the risk of aquaplaning on wet roads. That is rather scary!! NOTE - these blocks are higher than the safety warning bars around the tyre.
Can I also suggest you get hold of & fit a TPMS? That will give you early warning of any problems with your car & van's tyres.
