The issue is the tyre sizes available are not user friendly with the California size options. Have a look at Rogue and that will give you an idea.....looking at a set for my forthcoming motorhome but with the Michelin XClimate Camping option in the same size, just a non Fiat ET offset..... also some AT tyres are not good in the snow. I had BFs on a Defender and they were poor (nearly 20years ago so things would have improved) . However Pirelli ATR and Duratracs on my V8 Discovery were super impressive.(Snow , what snow?)
