Benefits to a bigger tyre on 16" wheel?

The exact opposite - the taller the tyre the further you can let it down, and the more ground clearance you will have when aired down.

Bigger tyres will take a bit of power from the car, so if your Disco doesn't have a power upgrade and you tow (and I know you do from your sig on MySwag

) you will struggle on hills and your fuel economy will go up.

Baz.

Mine came with 255/70/16 ... makes it 2000rpm at 90km/hr by the GPS ... speedo shows about 85km/hr give or take. No chip. So far, I'm happy with it.

I am currently also running BFG AT 255/70 R16 on the V8 and have not noticed any power drop. Nice size tyre. Happy so far.

I'm very impressed with them so far.
Very quiet and stable on the wet black stuff.
Very sure footed and great grip in the rocky and greasy tracks in the mountains.
I found that the steering is much lighter also.
Good value at $279 each fitted and balanced at Beaurepaires.

Now to see how long they last.

$302 for each tyre (245/75R16's with fitting extra elsewhere as I could not wait at the only place that had them for them to be fitted) in Darwin when I replaced the Cooper S/T 255/70 that delaminated on the drive across.

They are made in the USA version tho.

I went 255/70/16 Pirelli Scorpion AT (passenger rated) and they were good but going to 235/75/16 Maxxis Bravo AT light trucks are better again. On sand and in the sticks and for that matter on the road - they dont tram track like the wider ones too.

there are more costs than this to larger rubber:

. less responsive performance

. greater fuel consumption (particularly if an aggressive tread pattern)

. greater unsprung weight, possibly bump feedback - probably an idea to fit a Billie steering damper

. steering/braking implications

. higher gearing which can be an issue of the mark for TDs and for low range work

So really depends how much you need more clearance under the diffs and grip...
