I was wondering if narrower front tyres would be better ? I didn't get the chance to try my theory out as the snow has gone. I was thinking that rally cars fit narrow tyres in deep snow conditions .
They do yes, but invariably heavily studded too, if ice expected
It's the same in 4x4 land, all these fancy wide tyres may look good, but float/slide about on top (unless they're a true floatation tyre)
Many years ago, Land Rover themselves, found this out. during the Darien Gap expedition (using the then, fairly new, Range Rover)
They'd been
advised to fit wide tyres, to cope with the conditions, but found that diffs were exploding due to the extra mechanical stress
Cue, a return to narrower tyres (7.50 Firestone SAT, if memory serves), & no diff-problems
From about 1.10
Still a damned good tyre, but a crossply (was produced as a remould, on a radial casing)
