Hi guys,
I'm about to upgrade my standard 205/70 15s to 235/75 15s and was hoping to avoid having to buy all 5 tyres. Call me tight, but I'd like to avoid it.
I know that you can't have a different size front and rear when in low range, but can I get away with one smaller corner in low?
I have standard open diffs along with everything else.

i've driven 50 odd kays to work and back on 0psi and thought 'this feels floaty today'
i put it down to being used to driving my magna to work. i didnt realise untill that weekend when i attempted to air down.

You are tight. Simple. I have run "slightly" different size spares in Tough Tracks, only because I can still get off the track if the mis-match is fitted.
You'd be an idiot if you think that is safe on-road. I have my 5th 31 in the back when I am on-road.

It'll be ok for a short trip, ie: to the tyre shop to fix the flat. I'd put it on the back though, it would pull pretty hard if you had mismatched sizes on the front.

Thanks guys.
Don't get me wrong, I am well aware of the dynamic compromises of having different sizes side to side, but was just concerned about driveline windup that could damage my bits.
Cheers for the feedback though, I think I'll save on my spare for the time being, and bother when I embark on some touring.
