i always been told its the thing to do if stuck, but am now being told its dangerous and illegal?

I haven't had to do it this year, but carry a tyre inflator with me, so if i get stuck on a hill or something i can try going down to a low psi and then inflating tyres again once across the ice.

Anyone have any thoughts on this? what sort of psi would you go down to?

I'd say you're better off taking a shovel with you to dig your way out.

I'd deflate them to about 15 psi, but only if I was driving over constant heavy snow. If it's just for the roads that have already been driven on just man up.

i got stuck a few winters ago on a very slight incline, i just couldn't pull away and all these other people had to stop, then drive around me like normal

not sure if this was some sort of traction control fault or what, but didn't like it

you were revving the tits out of it with your hand down your pants more than likely. let the engine do the work and its alright.

suppose having the escort means it wont be so bad if some mongoloidz slides into you

i was trying proper hard to get grip, using no accelerator, just the clutch, tried getting half on a grass verge too, and it wasn't even that icy, i really don't know and still can't fathom how i got stuck

yes is ideal for the escort, i did a handbrake turn the other day, parked up, put handbrake on, then car rolled backwards into a wall/fence, think the cable may of stretched

I think the AA and such like are referring to folk NOT re-inflating once they are out.

If stuck, and you cannot get out at all (tried digging, grit/salt etc etc) then I cant see the harm.... but of course you need to reinflate.

You also have to remember that it will lower the ground clearance

I put my Transit tyres down to try and get up a hill. But when doing 50mph down a duel carriageway couldn't figure out why the back of the van was bouncing all over the place until I remembered what I'd done. They were at 10psi and meant to be 70

So yeah I'd say it's more the fact it's easy to forget to put them back up when on normal roads

Bulshit, i done it last year. Full psi i couldnt get out of my parking space so ran on 18 psi on the front and it worked perfectly. Yes is reduces stability but i was driving 15mph to work

Obviously driving 60mph on tarmac with 18 psi would be pointless and dangerous.

You can lower your tyre pressure to get more grip/traction on snow and ice - only lower it a bit though, not like 80% less of what tyre pressure you'd normally have though

People lower tyre pressures really low to help their 4x4s when they are stuck in desert sand for example.

Why do you think all the land cruiser boys drop to literally 7 psi (sometimes comes off the rim) in the Icelandic glaciers?

why do you think rally cars use thin tyres.....

lowering tyre pressure makes the tyre wider...

Because they're driving 3 tonne 4x4s over about 3 feet of snow...?

Can't compare a Land Cruiser in Iceland to an Escort in Essex

I have 18" rims there is not that much tyre to flatten and run flats, low tire pressures are not good at all

If it softens the tyre, you will have a larger contact patch with the ground, and therefore more tread to use. Less ground pressure but I would trade that off for tyre pattern particularly if the ground is already rough.

Rally cars use thin tyres on snow because the tread is already designed with that in mind, the compound will be softer which gives you similar results and they don't want to compromise on ground pressure.

Soft tyres on snow is a good idea but the AA advice is designed for dickheads who would either get it wrong or not put it back and then get on a motorway and do 85 mph 10 minutes later.

I normally just carry a spade in the boot and a flask full of tea, that way if i get stuck the spade can dig me out whilst i drink my tea.

that was a joke btw. i dont actually carry a spade or tea.
