Had 255/55/20 GG At's fitted this morning, must say it looks a lot better on All Terrains! It was a toss up between 255/55 and 275/45 but unfortunately none of my local fitters could get any 275/45's and i was getting desperate for some new rubber! Fitter put all four at 36psi, what does everyone else run?

I'd try a bit more psi on the rear, probably 38/40.

Have a play around and see what suits. I'd say 33-36 on the front and 36-42 are the parameters. 2006 D3 HSE (Original & still the best)-GONE

Sorry to keep dredging this post back up, but what are the real world differences between the 275/45 and the 255/55 GG AT? Aesthetically at least?

All I can say is that I'm very happy with the 255/55, they fill out the arch much nicer than the old 255/50 and looks the business on AT's

That's my old D4 on 275/45/20's but on LTZs.
But changed them for 285/50/20 LTZ's a few months later.

When changing to non standard tyre sizes, have people found that it altered your insurance premium?Bri
