Sorry to post what some might consider to be a pretty basic question but just want to make sure I get it right. I have a 2012 Vrs hatch fitted with 225/40/18 tyres now the details on the fuel flap say standard pressures should be as follows

Normal

Front 2.0 bar

Rear 2.1 bar

Fully loaded

Front 2.3 bar

Rear 3 bar

Which is fine but the pressure gauge I have only gives me the pressures in psi so I just wanted to make sure I have got the conversion right from Bar to Psi which i get to be as follows

Normal

Front 29psi

Rear 30.4psi

Fully loaded

Front 33.3psi

Rear 43.5psi

The reason I ask is i have I drive down to Cornwall at the weekend for a weeks holiday with me the mrs 2 dogs and what looks like half the Contents of the house so just want to make sure I get the pressures right first time so if you could just confirm my conversions are Accurate that would put my mind at rest greatly also any further help or advice you could give me regarding tyre pressures would be Gratefully appreciated

Thanks

Paul

1 bar = 14.5psi so your pressures seem correct.

 

I have the same car and tyre size and that is the pressures stated (in bar) on the inside of the fuel flap.  However, the rear pressures for fully loaded do seem very high.  I would have thought that 36 to 38psi would have been adequate.

 

I usually run my car at F31/R33  .

 

Hopefully some-one with more experience of the car will be along to give advise.

Follow the figures on your fuel flap and manual. Why  would you not?

I have used the  3 bar figure many times when heavily laden. The front and rear tyres feel the same temperature after a long run at 140kph.

I suggest you invest in a new tyre pressure gauge with dual calibration when the time comes.

I run mine at 35 Psi all round. to me it feels better than the pressures on the Fuel Flap

 

The wear is even, they don't seem over inflated

 

My personal choice

Definitely go higher than 29psi on the fronts, unless you want to be replacing pothole-damaged rims every 6 months.

I run 34front 32rear.

I tend to find that the manufacture specified unladen tyre pressures are an absolute minimum and that higher pressures tend to be better, particularly if you are doing some spirited cornering which puts pressure on the shoulders of the tyres so you want more pressure to push the centre of the tyre out a bit more.

 

That said I was also surprised that the laden pressure is a whopping 0.9 bar more than the unladen pressure - must be to do with the large loading capacity and relatively narrow stock tyre width.

We run our 17s on 32 all round unladen. So I'd expect higher than 29.

Don't a number of members run 34?

Thanks for all your comments and advice guys its much appreciated

After considering what's Been said here I'm going to go with 35psi in the front and 40psi in the rear for my trip to Cornwall. When I get back I'm going to go with 32psi all round and see how that feels while keeping a close eye on tyre wear.

Thanks

Coincidence...

We're also doing a longish trip this weekend with four adults and enough luggage for a long weekend.

I've opted to increase the fronts to 2.2 and the rears to 2.6 as the boot won't be fully loaded.

About right.

Now...

Each time I look at the fronts, set to 2.0 bar, they seem to be under inflated compared with the look of the rears.

The car seems to corner well with great grip, but the edges of the fronts seem to wear quickly.

I'm thinking....

Increasing the pressure on the fronts should put more of the centre of the tyre on the road, taking some of the load from the edges.

Question is how much of an increase and how much difference will it make to grip?

I run 32 all round and do 99% motorway.

 

Works for me.

1 bar = 14.5psi so your pressures seem correct.

Just noticed that I quoted the tyre pressures that I use the 'wrong way round'.  I meant to type F33/R31.  Think I'll try F34/R32 as used by a few other vRS owners.

34/32 for me.

Ok so in standard spec Skoda have the highest pressure in the rear tyres but am I correct in thinking most of you guys tend to have it the other way around with the highest Pressure in the Fronts and the lowest in the rear and have found that to work better

Another one at 32's all round.

I am with Andy, when I got all four of my wheels aligned at ABC on their Hunter Rig he said all low profile tyres run better with higher psi ,and he said 36 psi which I ran for two years with no problems , My R36 runs at 39 psi all round all year, and that is recommended on the flap .Tyres are more resistant to punctures when running higher pressures as well
