Increased use of petrol/winter fuel

during icy conditions you should reduce the air pressure to around 25 psi so you have more grip

In my opinion this is dangerous nonsense.

This may well adversely affect the handling.

Use the correct tyre pressures as per the handbook or the inflation sticker which is usually found on the driver's door post.

You can't just pluck numbers out of the air like this - the car manufacturer and tyre industry put a lot of effort into deciding the best pressures for a good balance between road-holding and comfort.

Don't go messing with them.

I don't know of any tyre company which advocated reducing pressures for winter driving.

If anyone does - post a link, please.

You are wrong - darkmatter is back and promised to not post nonsense


I've never heard of reducing pressures for icy roads.

I Will always follow advice from the manual or the Tyre fitting place I go to. If roads are too icy, I just won't drive. Work is a 10minute walk away, I would rather fall on my bottom than crash my car :P

That is very sensible - your bottom has a much larger crumple zone than your car

HOW RUDE!! implying I have a big bottom? :P

As long as no one sees, I will be fine :P

Yours is a low mileage car we all try to avoid. Do you ever run it a full temperature?

No reason your mpg drops.

I thought you were going to give good advice instead of nonsense.

There is if you let the air out of your tyres

There are a few things.


Check tyres are correct psi. Pressure and temperature are proportional for a given mass of air, so a drop in ambient temperature means you need to put more air in.


Then there is trying not to use too many "extras" like heaters, fans and de-misters.


You will also see a bigger difference from using different engine oils in the winter.

What do you mean, low mileage car? I have always thought I got a good amount of miles per tank for it especially since I do short journeys.
