    Keep trying to find enough to give my Landcruiser a test in the snow, but haven’t managed it yet.
    My Parents however have an L200 with standard tyres on it & it’s bloody useless! So they end up running around in an old SWB Landrover instead-much more capable.

    My wife’s got a Fiat Panda 4×4 with ‘proper’ mud & snow tyres(don’t laugh!) – it’s absolutely ace in the snow or on muddy fields & tracks. Always surprises me what it’ll get up & down (though I managed an unintentional (cough) 180 power-spin in it yesterday). One of her friends has also got a Panda 4×4 and last year she had to rescue her husband in his Defender! – can you imagine his shame 🙂 A 1.2L Panda trying to tow 2 ton of loaded Landy out was quite funny tho!

    His excuse was that the Panda is so light that it floats across places where his Landy sinks…..yyeees…OK 😉

    The trouble with real snow is that it gathers under the vehicles and ends up lifting the front end.

    If you do have a lot of snow, get one of these…

    your problem there is that even a landy isn’t heavy enough to provide anything like enough traction to push much snow. We used to use a Unimog with 2 tonnes of stone/salt in the back and chains and still run out of traction in 2ft+ snow.

    What gets me is the housewives in Volvo XC/BMW X3/5/ Range Rovers who think they can charge around like normal then when they hit some ice things go really wrong. Grrr.

    You mean the ones who say “We need a 4×4 because they don’t grit the lanes round here in the winter”

    So that’s £50 000 for a Range Rover or £100 for a set of chains for the car. Yeah, OK. 🙄

    It’s also pushing a button rather than grovelling around in the snow freezing your tits off trying to fit chains. Then taking them off again at the main road.

    You’re not married I take it? 😉

    A Unimog might be a wee bit hard to park in Sainsburys!

    When did you use one? They look like a lot of fun!

    Yup, no matter what vehicle and driver aids you’ve got on a non-studded tyred vehicle, there’s no getting around the laws of physics – despite all the BS the manufacturers come out with. IME, once you’re sliding on polished ice, a lot of the end result comes down to luck.

    (fwiw, my opinion is based on 30 years driving of all sorts of stuff)

    i would suggest its mainly down to tyres.

    fat and flat on modern 4x4s, and therefore pap as they compact the snow and you have NOOO grip

    skinny steelies on any 2000 ish or older 2wd will be better, and cut through it.
    and not as much of a fat lump to loose control of.

    i would hypothise, that if you got a 4×4 that was about 1.5T, not the usual 2.5-3, and then put skinny/mud/not-motorway-specific tyres on it, that would be your best bet.

    even skinny tyres on a 3T soft roader would be ok i reckon.
    not something moronic like this:

    You’re not married I take it?

    Good point. Even with a high lift jack and practice, it takes me a good 10 minutes to fit the chains to my Land Rover.
    I know there are women who would take that in their stride, but for the average housewife rushing to pick up Tarquin and Jemima from the crèche, it’s not really an option is it.

    However, as others have mentioned, four wheel drive may help get you moving, but when it comes to stopping, you’ve still only got four wheel brakes, the same as any other car.

    As has been said. Low ratio, difflocks, very soft tyres and a nice big diesel and you can creep down hell of a hill. I would argue that the another big virtue of my Landy is thefact that I can stuff it into a bank/hedge if all alse fails and it comes out as tidy as it went in.

    Indeed, with good all-season tyres my 1300kg 4WD is great fun and very controllable, except for poor ground clearance. And it’s stopping is faster but less controlled without the ABS, more controlled but about 2 car lengths longer with the ABS. With proper studded tyres I reckon it’d be even more amazing. I think one of my favourite cars in the snow was my pug 205 with 145 all-season tyres – I’d regularly walk past 4x4s even with all terrain tyres (presuming the driver must be useless) but almost always ripped the front bumper off in more than 6″ drifts 🙂

    You also usually have more suitable tyres. Which makes a huge difference.

    Yea, last winter I was getting a bit complacent and very nearly came to grief with the two other 4×4 in front of me. I’d got Bridgstone snow tyres on, ABs, EBD and ESP – but once you’re sliding down a 1 in 10 black ice covered hill, you’re stuffed! Once your ABS thinks the vehicle is stationary (at, say 2 or 3mph), it stops working and you very slowly slide into things. (I’d wondered why there were 2 other 4wds parked in the ditch 😕 )

    surf matt – in my yoof i lived in the peak district. My old man had access to such toys as a Unimog with blade and snow blower, tracked vehicles, 8 wheeled vehicles and lots of landrovers and quad bikes.

    They still have the Unimog i think but have sold the snow blower, they are crap in wet UK snow unless you have mega horsepower available to the front PTO.

    They’ve given up trying to clear snow up to the house, just compacts to ice so they leave cars at the bottom and use a landy with full chains, even with that they were reliant on foot for over a week last winter and the cars didn’t make it up for the best part of 5 weeks

    I like your style, Matt. 😀

    There is a method to (hopefully) regain control but it’s totally un-intuitive. When a vehicle starts to slide on ice, snow, whatever, the usual human reaction is to brake (and if it’s a manual vehicle, drop the clutch) which as all us expert MTBers know is the worst thing to do 😯 What you need to do is blip the throttle to get the wheels rotating again to regain control. Easier said than done when you’re starting to career down a hill…

    Well I needed difflocks just then! Coming out of an iced up field with a ramp onto the road (on which a Fiesta in front of me crashed into the hadge!) and it wasn’t having any of it. Difflock on and still sliding but made it okay. For a moment I thought I was stuck!

    Agree, but you still need some traction between tyres & surface to achieve this. Near zero/zero traction surface and control can be lost, and as psling says the remedy just goes against the grain – using the throttle in that situation just does not make sense in the brain, but it works if you catch it early enough.

    Locked centre and rear diffs, plus snow setting and max height on the suspension worked for the Disco in the Alps. 2 feet of snow up a hill was just about OK, but you just can’t see what you’re driving into (ditches and the like) so I really wasn’t all that keen.

    I used high ratio difflok just now – Low would have spun the wheels even more. Fully sideways as I finally made it!

    Indeed, done it and its somewhat terrifying, especially when you can feel the back end sliding and you’re fighting natural reactions, with your brain screaming noooooo at you as you press the throttle 😯

    As has been said above, its ALL about the tyres – we used to get the FC Montego vans nearly anywhere we wanted all year round due to sump pans and AT tyres.

    Running Grabber AT2’s here – just need some **** snow… robbed.

    Any advice from the experts on here about descending a steep snowy track in an automatic 4×4?

    My wife just had a fun experience in her new (to her) X Trail. she had it in 4×4 lock and also selected 1 in the auto box to limit her gear range but still felt the car running away down the slope, braking then just caused the car to skid – not a fun experience.The snow had been compacted down and she got up the track fine, but descending was not fun, especially with 3 kids in the car.

    I’m sure more appropriate tyres would make a difference and we’re looking into those, but are there any techniques which would help?

    Cheers

    Mango – just really, really slow and very very smooth – no dabbing of brakes, etc. That’s all you can do really. Lower tyre pressure will help it grip a bit more.

    1st gear in an auto will be too high to be of much use even if selected manually i reckon

    My brother just finished pulling a Disco and a Defender out of the warehouse unit he uses, in his Vauxhall Combi :mrgreen: It’s possible there’s a smugger man in scotland but I’d be surprised.

    Reverse is usually lower than 1st if you havn’t got a low box, but you’ve got to be brave!

    Going down, the car can only go as slow as the grip allows, whether you are trying to slow it with the engine or brakes (assuming either type braking is being applied to all 4 wheels evenly).
    Using engine braking might help a bit as it’s likely to be smoother.
    The basic physics says that reversing won’t make much difference either (although since the engine is likely to be in the front the weight distribution on a hill might make a bit of a difference I suppose, but unlikely to be much).

    The solution is better tyres or some shoveling + brushing 🙂

    OK, so to pull it back to the usual STW question – what tyres? I have a Disco3 with OEM Goodyear which, to be fair, did well in 12″ of snow last year. They did shuffle a little on the ice, but overall not too bad. Having had a blast around today again fine, but i am thinking about alternatives. Grabber AT2 or Yoko AT-S are in play at the moment, but so is a set of Winter Contacts? What’s your view; winter tyres or a reasonable off-road tyre that I can also use, well, off-road?

    Indeed. letting the wheels roll will always allow more control than having them locked (hence the reason for abs). It’s a technique I have to employ occasionally going down my steep little back street when it’s snowy – it’s narrow and has corners, so if I brake I just go straight into the wall. As you say though, easier to do when the consequences aren’t fiery death (would just be a dented car in my case since the speed is low).

    Isn’t that technically known as Curling?

    Probably best not to attempt it with a car…on a public highway.

    But you NEVER brake going down a slippery surface. or touch the clutch for that matter.
    My LR, which has an Isuzu 2.8 diesel in it which has a very low drive ratio moves so slowly in 1st , with no throttle that the speedo won’t move. If you tackle down hills likethis with some planning.ie go in slow, what you can cope with is amazing. My bottle goes before the grip on icy roads. Drop the tyre pressure as well to say 10psi and its great fun.

    Defender has an anti stall feature in 1st so you can crawl at super slow speeds without having to touch the throttle. Handy in snow.

    i used to have 1.9 diesel 205 with skinny tyres, it was great in the snow.

    When i was taught to do steep decents in landrovers, they always made sure your feet were off all the pedals, and you let the engine do the work, and apart from occassionally blipping the the throttle you were fine.

    Got to drive from Edinburgh to Wales tomorrow – in an Avensis estate – not looking fwd to it. Spent the day watching people slithering around either driving way too slow and dithering or way too fast and over revving.

    That’s fine if there isnt a T junction at the bottom. This morning I was creeping down the hill in 1st and came to about 15ft from the queuing traffic crossing the T at the bottom. HAD to go for the brakes as there was no room left and I was going too fast to steer. ABS went mental but the steering was still just about usable, all locked but it was 50 % polished ice so I just had to rely on the guy at the bottom predicting it and waiting for me to slide into the space in front of him like a slow-motion rally driver 🙂

    Does the X Trail have a transfer box? If so it would help to select ‘low box’ and lock into 1st gear. Having said that, the brain advises you’re losing conrol well before you actually do lose control so it is probably just a case of practice and confidence! Technique? We’ve been known to run autos down slippery slopes forwards with Reverse gear selected; allows the wheels to contra-rotate with a surprising amount of control but I certainly would not recommend doing this!! [especially with all the electronic wizardry on modern vehicles] 😕

    I know of someone who used this technique in a manual hilux 4×4, it worked fine to control on the slippery stuff and allowed him to go slow enough to dip the clutch and brake as he hit the clear tarmac.
