Tyre pressure advice.

Hi all,
Decided to do the tyre pressures today and checked several online guides which consistently gave me these details;-

Tyre Pressure results for: (my cars registration number)

Make: ROVER MG
Model: MGTFSPORTS
Colour: GREY

We have found 1 tyre size that matches your vehicle.
Your tyre pressures are as follows:

Tyre Size
Front Tyres: 195/45R16 W 80 - 1.7 BAR / 25 PSI

Rear Tyres: 215/40R16 W - 2.5 BAR / 37 PSI

Only my tyres are;- Front 185/55/R15 and Back;- 205/50/R15. I measured the wheels at 16 inches across the centre. So, couple of questions please..

1. Are the different tyres because of the wheels being slightly larger?
2. Would the tyre pressures be the same?
3. Anything else?

TYRES

The wheel size is measured where the rim of the tyre sits on the wheel, so a 15" wheel measures about 16" across the outer face, confusingly. :yesnod:

Same size as mine Leigh, If it helps I've been putting 36 in the rears and 28 in the fronts and all seems fine. I think they suggest 28 in the front for 'sporty' driving and 26 for 'comfort' driving, although I could have misread that somewhere.

I'll pop to the air pump later and see what's in there already. Shouldn't be too far off. But that guide says 26 front, 28 back. Not sure I want to over-inflate with that dead body in my boot.

Cheers both.

F is 26f/28r
TF is 26f/36r

Aah.. apologies and thanks both. Right, must write that down. I'll forget overnight.

David is quite correct, not advisable to run them lower causes excessive tyre wear. you should always come here first, there is a lot of other forums giving incorrect information!! :rant:
