Changing tyre sizes is always a compromise. Personally, I never do.
Tyres diameter is carefully matched to engine performance and gearbox ratios. You will always suffer some sort of detremental effect to the performance or fuel consumption.

As for the speedo, that is not an issue, as you can normally buy a gear fairly cheaply to correct the speedo. If you look at where your speedo drive goes into the gearbox, you may find it has four positions on it with different gear teeth numbers. You change the gear and then rotate the plate to the new position.

hi beauges,
on my rodeo i have fitted 31x10.5 r15 they are wider than standard and give a height increase of 10mm over standard. ive done extensive offroad including cape york no problems, only slight touching on rear inside gaurd on crew cab but only at extreme suspension flex. always wondered about speedo but have checked and if any negligible.
hope this helps regards peter

Hey mate. I did a lot of research when buying new tyres for the ute.

If you want to stick with the standard wheels, you can go for 215-85-16. These are the same diameter as 31" tyres and will give you an approximate lift of 15mm. The other option for standard wheels is 235-85-16, which are the same diameter as 32". I reckon that these would be too tall for the Rodeo though.

225-75-16 tyres will fit, but are the same diameter as your current 205R16.

The 215-85-16 size is fairly rare. The only brands I could find are; Cooper, Hankook, Kumho, Kelly and Toyo.

I ended up going with new 15x7 wheels amd 31x10.5x15 tyres. The wheels are the Sunraysia style in the 'Navara' offset. These cost me about $40 each. Mine do not rub at all, even when on full steering lock. I have a flat tray so no worries there either.

If you go with the 31" tall tyres the speedo will read under about 3%. ie, when your speedo reads 100kph you will actually be doing 103kph.

I haven't found any negative effects at all.

You will find that you can usually buy 31x10.5x15 tyres cheaper than any other size because it is so common. This is the biggest plus to changing tyre size, along with getting the extra width and height.

Hope this helps!

To Beauges
Did you get your tyre problem sorted?? What did you end up fitting/ I've seen rodeos on standard 16x6 rims with LT225/75R16 and they looked ok.
