Tyre Pressure

[Golf Houso]

Thanks Golf Houso

No worries, now here comes the fun part, experimentation !

I tend to run 38 to 40 PSI all round.

Lora, just remember to play with your pressures when the tyres are cold. Once they are warm, the air in the tyres expands, some times at different rates,thus giving you a higher reading, so it is better to do this when the tyres temps are all the same when cold.

yeah i run at approx 38psi all round. it's a good pressure for both comfort and handling. my car certainly does not bounce around the place and my handling is very good....so, i'm happy with it and it's what i'll be sticking to.

in australia, people tend to run their tyre pressure at a bit less than in the fuel cap (on imported cars) due to our climate and the quality of our roads.

The other thing you guys need to remember is tyre wear.

Too little pressure and your tyres will wear on the outside, too much and they wear in the centre. So you have to find a happy medium for that too.

40 up front and 38 rear sounds about right on a polo with those tyres. more in the front because of the weight distribution. .

I'm currently running 35 all round and very happy with the grip. At 40, I felt a little unsafe on roads with tram lines in the wet.

With the increase in tyre pressure, the centre of the tyre rises and as described earlier by Preen increases wear. It also means that water moves much much better across the tyre due to the wider surface and higher center, so i can't see why your car would perform worse with higher PSI in the wet when it should be the opposite.

Because with the center of the tyre being raised, it may present better water dissipation, but it also means less of the tyre tread face is in contact with the road, which as you know equates to less grip.

Yes that too, but even the manual suggest to increase PSI during heavy loading or wet weather.

Ahh, fair enough...I understand about the heavy loading, but that is weird about the wet weather, and goes against everything I have been taught.

Yeah thats what I thought as well until I few people told me otherwise and I had a look at the manual, at least I thought I read it in the manual
