tyre pressures???

goucho_2

I have just bought a 2005 astravan which is fitted with after market alloy wheels and tyres which are not the standard size, they are 205-50-16 w rated , i wonder if any one knows the correct tyre pressures for these,::

alo6

37psi.

had a look at a psi chart, but it all just depends on your personal preferance (and weight), but its a benchmark to work from.

For the Estate which the Van is derived from it is 36PSI front and 42psi rear when fully loaded - 30psi all round for load of up to 3 persons (so the former will be more appropriate for a van).

Those pressures are for 205/55/16 though....

upgrading tyre size makes no odds

It most certainly does!

why does it?

30psi in a small skinny tyre is the same as 30psi in a big wide tyre
pressure is pressure regardless of tyre size

Just to keep it very simple for you, look in any manufacturers handbook where different tyre sizes can be fitted eg. my Vectra.
Larger alloys fitted as an option have larger tyres and have different pressures.

You should not be posting dangerous information on this forum.

Until I retired, I was a Car Tyre Specialist for Michelin Tyre PLC.

Now get a life and stop commenting about things you don't know.

Apoliges about the 'get a life 'comment.

On looking back to your previous forum input you have given both helpful and sound advice.

In this instance you are wrong and your previous comment lost you all credibility
(I thought you were my friend Amanda).
