correct tyre pressures? - tomandjerry56
just been out and checked my tyre presures on my vauxaul zafria and they need pumping up but i cant find my manaul that tells me the tyre pressures was wondering if any one could tell me the tyre pressures if possible

These days car manufacturers tend to have data plates on the car showing these details. Open the front doors and check for plates on the pillars, or maybe on the inside of the fuel filler flap.

Having owned several Vauxhalls, I have never seen the tyre pressure info anywhere else but in the handbook.

Not being funny, but this is really a case of RTFM for this sort of info.

Failing that, a couple of websites that may help:-

Just found this chain having googled for vauxhall zafira tyre pressures. Took the RTFM hint but left me more confused...
My zafira manual tells me that 1.8 model should have:
- 29psi front and back for up to 3 passengers
- 30 at front and 38 at back for full load ??? looks like a big jump to me
- 36 front and back for some kind of 'eco' option, again a big difference but manual gives no explanation about this...of course I want to economise but is there a down side to doing this? Why wouldn't this be given as the 'standard' approach if it is 'eco friendly' ?

oh and a couple of websites I checked stated 32 front and back.

can anyone give me some clear advice on this. 29psi looks wrong, the tyres look pretty deflated at this pressure to my eyes, but it's what the manual says.

Why not just ring your local fast fit place who fit these all day long they will recomend you the best pressure laden or unladen.

Radial tyres will always give an impression they are under-inflated when viewed.
30 at front and 38 at back for full load ???


Full load means that all the seats are all in use / and or / the rear is full of luggage. It needs that big jump to cope with the extra weight in the rear of the vehicle.
36 front and back for some kind of 'eco' option


This will give the tyres less resistance to the road, and thus improve fuel consumption. The downside is that it will be like driving on ball bearings, won't handle as well, and will wear the centre of your tyres down.

If the tyres 'look' better at 32 psi, then leave them at that setting for most of your day to day driving.

Or as suggested, ring a couple of garages up for a 2nd opinion.

Yes, follow the advice given in the manual.

Not at all uncommon to have a significant pressure increase for full load running. I'd always refer to the manual, not websites.

Eco option is not well explained in the note at the bottom of the table but essentially designed for minimum fuel consumption. Having driven my Astra (albeit one with the sports suspension) unladen with full load pressures I'd suggest these will make the ride very unpleasant. You would suffer to be 'green' which is why it's not standard.

Even at these pressures radials will look partly deflated. It's normal.

DD, neither had I seen this - until we got a Tigra B! This does have a tyre pressure sticker in the door aperture. Amazing, isn't it?

John S,

Certainly is. How new is the Tigra? *maybe* Vauxhall have now started putting a sticker there on all their range of models?

It's 3 months old. Haven't looked at any other new Vauxhalls to see if this is now standard.

My Zafira is supposed to be 29psi all round but I run it at 30psi front & rear & it usually runs with 1 to 3 adults onboard. When SWMBO suddenly announces my kids are taking 5 of their friends with them I usually only have time to assemble the extra seating & don't have time to change the tyre pressures!
In my experience fastfit places bang in about 33psi whatever the vehicle and can't even be bothered to inflate each pair of tyres on the same axle to the same pressure.

This "ECO option" with raised pressures.... As I understand it the manufacturer recommends a pressure setting that is a compromise between handling (hard) and comfort (soft). I run my Vectra B and even older Clio with 36 psi all around, and I find they handle better (hard to tell with the Vectra!). They certainly feel very baggy after any garage has let the tyres down. So if this improves the fuel consumption too, I am indeed on to a winner.
I did try this on a Focus hire car once - and ended up with 38 - 40 psi and it was getting better all the time (not least after the Vectra). I have gradually hardened the tyres on every car I have had for the past 35 years - and I think that the only car that didnt benefit from harder tyres was a flabby MkIII Cortina.
What I have found is that if I blow tyres up hard, then they seem to take a few miles to bed in or something - ie before they hang on as they should.

I use much the same strategy with SWMBO's 1.8; 32 psi all round , for much the same reasons.

One fastfit type place actually managed 10 psi difference between the two front tyres I had changed on an Omega!

is set all zafi's at 2.2 bar as per Tis in old money thats about 31.5 psi

Thanks to everyone for the comments, very useful. Having been driving around with tyres set at 29, it just doesn't feel right, will go with the suggestions of upping to 31-32, and whack a bit more in the back when really loaded up.
I think the manual should really explain things better, and point out the downsides of the eco option...and presumably 36 isn't a magic eco number, sounds like a gradual scale of improving efficiency and declining comfort/tyre lifespan above 31sh up to 36ish (people seem to have differing views on the effects on handling). Down to individuals to manage the trade-offs and find their own preferences within this range themselves I suppose.
