OK, regarding tyre pressures - a lot of people lower the pressures in winter to allow more surface contact + more grip from the tyres....

What value would people pick for the lowest 'safe' pressure to go to - There aren't too many potholes round warminster luckily, but still wouldnt want the thought of my alloy smashing coz my tyres were underinflated, but would like a little more grip to avoid the feeling of riding a 1.5ton sledge!

I know a lot of smart arses will no doubt come along and say there is no set value for this as the lower the better for ice, but higher the better for wheel damage so its a balancing act somewhere between, but just wanted to gauge roughly what people ran in winter.

Get voting!

(oh and I know technically it isnt necessarily an Leon related post, but it is obviously tyre specific and aimed primarily at LCR wheels 225/40/18s)

Well that site clearly offers good advice:

Pump the brakes slowly and gently if your car lacks antilock brakes. If you start to skid, let up on the gas and the brake, then shift into neutral. If your rear wheels are skidding, turn smoothly in the direction you want to go. If the front wheels are skidding, avoid steering until the car slows enough for the tires to regain traction.


steering the same way as a skid is clearly how to get out of one?! and everyone knows a car is more stable with no drive?! :S

The best advice i can give is drive slower..... leave more room to stop unexpectedly and most of all buy the best tires you can afford!
Oh and dont let them get too low as they just dont grip! I never lower my tire pressure as i have never seen any tyre maker or car maker say to do so! People lower them then forget to reinflate them later!

Lol it wasnt supposed to be a thread on how to drive in the snow, was just wondering what tyre pressures people ran!

Just because tyre/car makers don't say to do it doesn't mean you can't - car manufacturers dont recommend you use aftermarket equipment...............

Manufacturers actually recommend running 3-4psi more during the winter because the colder temperatures drop the pressures. I do not know what temperature you are supposed to put the extra 3-4 psi in at though. If you did it at say 10 degrees then it might give you the right pressure at Zero. But if you did it at -8 degrees then when it warmed up to 10 degrees they would be over inflated. Unless they are saying that the tyre generally will generate less heat so you will not see the same pressures you see in the summer, hence why you need the extra pressure in them. Did that make sense......

I just run them at 32psi which is checked when cold. Think I set them last when it was about 7 degrees air temp.

Also to add, does you tyre run better with a puncture or when properly inflated?? Why take pressure out.

I took my car to a local tyre garage at the start of the week and they recommended 34psi in the front and 32psi in the rear. Just my input. :) They didn't say anything about dropping pressure in the winter. The way i see it, tyres have a recommended pressure and are made for most, if not all, weather climates. There shouldn't be any need to modify it, just drive to the weather conditions.

In the old days it was said that letting air out of tyres improved grip by allowing tyre footprint to increase as tyre bulged out at bottom, but now i think they dont advise it as they say that causes the tread pattern to disstort and reduce grip on snow.
On tractors and the like ive reduced tyre pressures alot which does affect grip by a big amount and creates a bigger foot print and reduces ground pressure when working, but thats tractor tryes and not car tyres. I leave mine at the standard pressures in snow.

I did quite a lot of reading on this last year and initially lowered tyre pressures about 5psi in an effort to find more grip on the ice.. I found out that it is a better idea to ADD pressure instead; this causes a smaller footprint, but the edges of the tread cuts dig in better in icy/snowy conditions. 225 tyres are very wide and as such will never be great in snow, so do drive with caution..
