I have a 2012/62 facelift and have the choice of 5084 alloys with Pirelli Scorpion all season 255 55 20 or Stormer alloys with GG AT3's with 275 40 20. Now the AT3's have 9mm left on each tyre and the Pirellis are brand new and I know will be more comfortable, which would fit the look of the vehicle given it's age. Any help appreciated as I need to make a decision today.

No contest for me, AT3 every time.

In truth though I guess it depends what kind of driving you do, I'm using narrow, muddy lanes with huge potholes, interspersed with a little off-roading and deep mud so for me road tyres are useless.

I also ditched the 20s that my car came with and bought a set of 19s as I think the 20s look stupidly large and the ride quality on them was awful.

TL:DR AT3s, resized to 19s if you can!

What use are you putting the vehicle through? If you only ever drive on tarmac, get the Pirellis. If you want to go out and about off road, get the AT3s. That's really the important question and answer.

As for which looks better - for me a deeper sidewall looks better but many others think a skinny rubber band tyre looks best. It's whatever you like that matters, really. The 255 has a much bigger sidewall (140mm vs 109mm) than the 275.

Bear in mind that the 255/55/20 is a much large diameter overall than the 275/40/20 (787mm vs 729mm) and the speedo is likely to be out, and the odometer will be well out. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Thanks guys, looks like I may have missed the Pirelli option and I am on 255 55 19's at the moment but need replacing very soon. I think it's no more off roading for me so GG's are an over kill unless I just run them through this winter and take a risk with 40 sidewalls.

I have 255 55 20 on mine. I'm with Wayne that a deeper sidewall looks better on a 4x4 and a bit more purposeful. But yes, it's personal preference.

The 255 55 20 are more comfortable than the 275 40 20 they replaced on my old wheels. High speed cornering is a bit more interesting though - sidewall deflection can be felt, but they are more than adequate for my needs.

Concerning the speedo error, if my cruise is set at 70mph, my speed according to GPS is 71-72mph.

Here's a picture of the 255 55 20 on mine...

Hi Kev, must admit to looking at that picture in your gallery before I posted and good news. The chap with the 5084's and Pirelli Scorpions as come back to me and I have bought them so going to get hopefully later today.

Awesome. It'll be good to see some pictures with the 5084 style wheels on the L320  Kev

Hi RRSTDV8, the Michelin Crossclimate. is available in the 20” size and could have been a contender but these wheels came up with new Scorpions fitted by Landrover so a no brainier really.

I think your wheels will be 9j rims and I'm pretty sure 225 tyres need the 8j rims but quote me I'm sure body with a lot more knowledge and credibility will be along shortly.

Land Rover fitted 275 section tyres to 9.5" wheels, and 255 section tyres to 8.5" wheels.

If you fit 255 tyres to the 9.5" wheels, you will have zero sidewall above the rim which will result in damage if you get near a kerb.

Thanks everyone - I’ll stick with the 275’s
