Kerny with bigger wheels the rig will sit higher... ...will it still fit under your garage door? You wouldn't want to bring it home and find it doesn't fit...

As long as your tyres are in good nick, you'll be fine with the 12" wheels. Keep the money for petrol instead (& XD whatsitcalled oil)

FWIW when I bought my trailer I specified 10" wheels for the whole garage door thing reason. (I have an interesting attack angle with a short steep hill so all sorts of momentary strange geometries happen over a boat's length of travel - half of them with the boat still half in the garage).
It's like all trailer running gear - keep it maintained & it'll keep going. OK, smaller wheel the bearing turns a bit faster, but if it's maintained & lubricated, what's the problem?
Also smaller wheels = easier launch - I can't remember the last time I actually unhitched to get the boat on or off.....

The garage miscalculation for me was on width 
Like I said before I just thought that it would be a safer option to have larger wheels for long distance towing and speed.
Dhd's comment has got me reconsidering though as that XD 100 is bloody expensive ...

Would a larger wheel not give a high centre of gravity and thus negate the slight advantage of the longer circumference? My old mini's use to speed down the motorway quite happily on 10" wheels and the upgrade was a 12" wheel.

I run one or two round my middle but haven't worked out how to make them run flat yet

I had 12" wheels on my last rig and had a blow out in a remote enough area, l had a spare and was quickly back on the road but as I was on holidays and doing a bit of travelling I decided to try get the old tyre replaced. Went to a few different tyre places and none stocked 12". They Said they were fairly rare nowadays and would be a couple of days to get them in.
Ended up going on without.
13" is definitely easier to come by for both wheels and tyres.

If/when this happens, it may be the time to consider a 13" 'upgrade'

No way would you do this recovery so easily with 13" wheels.

I have 16" rims on my trailer now with 235/70R16 on and the need for more water is the only downside. Rides much better than 13" on rough roads, which is all of them around here. My solution was to specify 5x6.5" PCD with M16 studs and then you can use any Land Rover rims, so I could easily go to say 33x12.50R15 tyres to spread the weight on soft ground, though I'd need even more water
Also, as TG will confirm, getting spares for these is difficult...

He.. He.. , I was going to mention the tow car Chris but thought that I'd better not, fearing the backlash of all you Landy owners on here. But yes you are quite correct

My trailer runs on 16" rims as well. I use 235/85/16 bf goodrich mud terrain tyres. It does mean going deeper to launch but the plus side is it goes anywhere the defender does. It tows on the road without any problems plus no more speed bump issues!

Why did I guess you'd have a Defender to tow that.
