Angus, depending what your touring plans are.... it would be wise to settle on a tire size that is common outback.

Being a D4 owner running 255/55/19's I know how much fun getting odd sizes can be away from suburbia...

I hear you, and more and more reading doesn't really point to "wider is better", quite the opposite in fact. In any case it sounds like I've got a great middle ground with my already fitted 245/75/16 size.

(now I kind of like the option of the skinnier tyre at 235/85/16 but let's not go there)

Got me wondering though, I test drove an automatic 300TDI when looking to buy my Disco years ago, it drove really well, then when I bought my Disco which had a bunch of performance tweaks like the injector pump and intercooler etc. and was a manual it seemed to drive a little slower than the one I test drove a while ago that didn't have all the off-road mods on it, at least not as many.

The one I test drove and didn't buy probably had stock tyre size on it. Mine is slightly bigger as already discussed.

I wonder if this speed difference I felt was because of the gear ratio being slightly out with the 245/75/16 rubber and if there is something I can do about that from a gear ratio point of view, or if it's too small a difference to be able to do anything about.

I haven't been into my car stuff for years, I'm having a lot of fun with this gotta be honest haha

That could be a factor, but autos can work well with turbo engines as they keep the turbo on boost.
