Ps: @Ronski...
I just tried an experiment... could I get up my drive, without clearing away the snow, now about 4 inches? Unfortunately, not a chance. No matter what strategy, traction control enabled/disabled, 1st gear or 2nd, take a short run at it, each time same result... within half a car’s length on the 20-25% gradient, I am slithering back down again. Had to give up in the end as there’s a brick wall on one side, danger of slithering up against it, which would be embarrassing.
I did try the same experiment years ago on the Nokians, similar amount of snow. I was not only able to get all the way up, I could stop halfway, hold it on the handbrake and restart again with no drama. For me at least, I’m afraid the Cross Climates are just nowhere near as good in snow, the difference is night and day. But repeat, overall I am satisfied, they are an excellent tyre the other 364 days of the year.
