Have been going to check the tyre pressures on my car looked at filler lid only shows Bar and KPa so did bar conversion. Car fitted with Dunlop 215/45R 16

the economy setting is 2.4 Bar = 34.80 psi and a softer setting 2.1 Bar = 30.46psi

 

Thinking about changing to softer setting as you seem to feel every bump in the road the car is fine on a decent surface but the road where I live is not brilliant its a pretty bumpy ride down it.

 

The downside is I may get a worse mpg wonder if anyone has altered their original tyre pressure or it could be the pressures are wrong on the car Joe 

 

 

Give it a go.

2.1 bar sounds about right tbf.

It is quite a low profile though so itll never be too comfy, always a little crashy.. In a fabia especially

I found upping to 34psi made the handling a bit better.. 30 was a bit draggy on the steering.. but then if you do a lot of motorway driving you are always supposed to add 5psi and if you are carrying a heavy load on the motorway, make it an extra 7psi.. according to Dunlop.

If you want a bit of comfort & don't want to totally kill the crispness of turn-in, try 2.1 or 2.2 bar on the rear & 2.3 or 2.4 up front

I was just wondering about this, as i picked up mine yesterday. 

Going to head over to petrol station and see what pressure it has now and gonna change it to 2.2 with 2.4 on front  

Going to test and reply  

Pressure was already 2.4 on all. I left it like that. Even the way it is, suspension and drive are still 100% better then the old 53 reg corsa i had before )

I never get the mentality of people who put more pressure in the rear than the front.. the common response I get is "..well you might have a load of kit in the boot.." but, yeah.. my response is.. "there's a bloody big engine in the front!" - kinda evens things out a bit doesn't it? "hmm.. didn't think of that.." is the counter-response..

So it is, but anyway the factory recs still are different and higher pressures back, different for different loads. Road behavior or whatever, there might be a reason. All VAG cars I ever owned were the same, the few odd ones have been a bit different but none have had lower pressure recs back than front, but equal.

It is always sensible online to take advice and opinions of people you do not know with a pinch of salt.

You never know with what mentality they think with or even what they understand sometimes.

(include me in that.)

Id still value the car manufacturers recs higher than a the recs of a random tire company. No puns intended.

Agreed.

But then the Manufacturers do have cars that have recommended lower pressures at the rear compared to the front,

which was the point of posting the link.

After all they took their pressures for the table from official recommended pressures.

I think many don't actually think about the tyre pressures and what effect they have.

 

Not many realise that lowering the pressure will provide higher ultimate grip when cornering... except the turn-in won't be crisp / immediate & it feels "unstable".  You actually have to have a lot of nut-sack to explore the limits.

 

Then there's the difference to under/oversteer; carcass temperatures, fuel economy, tread wear patterns, steering feel, etc.

 

As for manufacturers pressures being the only thing that's correct...  I've said for years that an Octy2 with 205/55r16 should be running 36psi+ and had the good folk of briskoda tell me I was a fool because the decal inside the fuel lid said 32psi.  Surpise, surprise the Octy 3 which is significantly lighter recommends 36psi for the same size tyre.

It is interesting the issue of tyre pressure, and as a motorcyclist, it is important to know why pressure is important and the effects different pressures have. If your vehicle, whatever it is, is designed for off-roading then you have larger tyres with deep treads and LOW pressures, to balance ride, grip, wear etc. So similarly if your vehicle is designed for road use, you have thinner smaller tyres with shallow treads and HIGHER pressure. All of this is to acheive the same balance. In a car, fronts need higher pressure than backs unless engine is rear mounted (porsche etc) because that's wear the load is. When you break suddenly the front is forced downwards towards the road compressing the front tyres, and that is counterbalanced by the higher pressure.

If you change the load of the car, then you should also change the pressure in the tyres to compensate. "manufacturer recommended" is just that, recommendations, and no substitute for a little understanding and common sense. Going a couple of pounds higher than "spec" isn't a bad idea in Winter carrying 4 passengers..

So many scenarios, so many right answers.
