Unknown, but imagine there's no difference. No, an easy couple of hours work, just a bit cramped.

It is only the actual speed that will change.

You will have to use your GPS to measure your actual speed, the tacho will be correct.

yep, 2000rpm on tacho at 100klm on speedo and GPS. 255/85

Same for my 285/75 2000rpm's 100k speedo and GPS

Drover, do you think the steering is any heavier with those wider tyres. Or do you recon hydraulics just cope with that stuff.

Currently I have a BBar and winch, bush bars/side steps off mine and I reckon the power steering in lighter, to the point where it can get a bit too light at 100km on an uneven road. It would be somewhere near standard though so I guess I've become accustomed to a slower sprung mass as it wallows about.
I have a set of 285's that may make it on one day. Just thinking of a cumulative effect.
