Who owns a Mondeo ST220 / ST TDCI?

Puzzled · 13 Mar 2013 at 22:47

Hmm might pump mine up a bit then.

I run 36 front, 40 rear (usually have some stuff in the back).

Maybe I've been reading them the wrong way round all these years!

40 back? Surely you don't have stuff as heavy as a 3ltr V6 engine and gearbox in the back?

Anyone got the ST220 user manual to hand? What does it say exactly re: sports suspension and tyre pressures?

Rybo89 · 14 Mar 2013 at 10:20

34- 31 normal

continuous road speed over 160km/h. Also for vehicles with sports suspension regardless of speed:

43- 38

Told you I wasn't crazy.

Imy · 14 Mar 2013 at 10:45

43!!!

Was it so difficult for them to put the right sticker on the fuel cap!

Time for you nay-sayers to get yer tyre inflators out

Rybo89 · 14 Mar 2013 at 11:17

Has the ST220 got 'sports' suspension? They still label the ST220 in the 34-31 tyre pressure guide.

Kerb weight 1490kg am I right ?

I think that is quite light given the size of the car.
I am interested now though to find out the correct tyre pressure as I am pretty sure mine is 32psi all round.

Imy · 14 Mar 2013 at 13:15

I've got the original options brochure at home which should say if Sports Suspension was standard on the ST220. It kinda makes sense that it would be.

The kerb weight sounds right.

DogsBody · 14 Mar 2013 at 13:17

in that case I think it is pretty light.
I used to own an Audi S3 which is way smaller than the mondeo and kerb weight was about 1420kg.

Imy · 14 Mar 2013 at 13:20

Did it have 4WD?

Imy · 14 Mar 2013 at 18:55

Right then.

The brochure states the ST220 comes standard with sports suspension:

and the manual states to use 43f / 38r for any car with sports suspension and a normal load:

Is there any other model that uses the 3L Duratec ST engine apart the ST220? As the manual looks to be contradicting itself.

Titanium?

Rybo89 · 14 Mar 2013 at 20:49

So we all need to put are pressures up then? (except Howard and his smug grin

)

blueboy2001 · 14 Mar 2013 at 21:16

It is contradictory because only the ST220 got the 226PS 3.0 engine in the UK, the 3.0 in the Titanium was the 203PS.

The 43-38/44-46 pressures are stated for a continuous road speed over 220Km/H - 136MPH!

It seems the acceptable range is 34-44psi in the front and 31-46psi in the rear.

The midpoint of those values is 39psi all round!

Imy · 14 Mar 2013 at 21:47

There may have been plans to make the 226 PS engine available to other models at the time the manual went to print so they left the standard suspension tyre pressure reference in there. That's the problem you get with manuals that cover more than one model.

One other thing, as I mentioned in another post (http://forums.overclockers.co.uk/showpost.php?p=23850856&postcount=706) I have been getting uneven tyre wear. I wonder now if under-inflated tyres is the cause.

I'm going to try 43/38 to see if it helps even out the tyre wear. I may have to live with poor traction for a while.

Howard · 15 Mar 2013 at 08:06

You won't have poor traction unless you have poor tyres. I know I certainly don't

All S3s have haldex 4WD yes.
I understand that this adds weight but I can't get my head around only a 70KG difference between the behemoth (ok maybe exagerating a little here) that is the mondeo and the Small hatchback that is the S3
