Currently running a set of potenzas on my vrs diesel at 2.7bar due to carrying a full load for a few days.

I've covered 9.5k miles with no problems and that's been with the 2.4bar since day one, the car feels quite nice with the 2.7 so I'm tempted to compromise at 2.55 - without running the gauntlet of being overinflated and provoking uneven wear.

skoda state 2.4 for normal loads I'm wondering what other people are running, and most importantly any problems?

I run 19" Pirellis as per the door card which is 2.7 bar for normal use

 

I have run them at the "eco" (which is 3 from memory) setting and found them a little firm, but still usable.

 

If you are running 18" @ 2.7 you should be well within the limits of the tyre (as you said, this is specified for full load) so all good!

I run my 19" Nokian zLine at 3 bar, as per recommendation of the tire installer shop. I tried the door card 2.7 and I did not like how the car handled. But indeed, they are a bit bouncy.

I experimented a bit in the first year of ownership. 18" Sport contacts. Went as high as 40 psi where they started to be crashy and settled on 37-38 psi. Wear is even, ride seems fine, grip fine, fuel economy noticeably better than when down a few psi, and a bit of extra protection for the rims in the event of meeting a big pot hole.  I ran my nokian winters at 38 psi too.

I run mine at 36 psi all round for normal use and it seems a good compromise.

Higher than recommended pressures can also enhance road safety

A common theme in defensive driving courses here in Aus is to inflate tyres about 4psi over manufacturer's recommendations.

Under very heavy emergency braking not only is most of the weight of the car thrown onto the front tyres but that weight is multiplied by the braking g force.

Without sufficient inflation to resist it this can cause deformation of the tyre walls which lift the tyre centre off the road reducing the contact area and effective braking.

Before ABS this effect could be seen from crash scene parallel skid marks from the outer edges of the tyres only.

 

I was told this years back when I did the course and apparently it is still preached according to an motoring web-site journalist who attended one such course recently.

For 18"s on the VRS that is pretty much Skoda spec anyway isn't it?

 

I found it interesting how under-inflated my tyres were from the dealer when I picked it up - around 34ish I think, which is both way lower than manufacturer spec for 19"s and obviously compromised the handling during spirited cornering.

I carry a 3/4 to a full load in the boot most of the time, I'm on 18" rims & I run 2.5 bar at the front & 2.7 bar for the rears, in the petrol cap there is information on what bar/psi to run for your size tyres & what load you are carrying etc...I always drop -2/-3 bar from what it specs, I have only just replaced my rear wheels with the fronts, vice-versa & my tyres have been wearing very evenly all-round, but now have 8mm at the fronts & 6mm to the rear & this is after having 4 x tyres fitted in october/november last year. 

Interesting. On my MK11 I had to run 29psi to get even wear, and that was supposedly a heavier car. Running 32 in my 19's now, will see how they wear.

At work we have a 15 plate Passat on 18's, a 15 plate Leon ST FR on 18's, a 64 plate Superb on 18's and an 11 plate Leon FR on 17's, all of which only wear evenly if pressures are between 29-32 psi. Maybe it's my gauge.

32 is pretty low if you have 225/35/19 on - you may risk damaging your rims on bigger potholes or bumps and the handling will be compromised - noticeably so I would have thought.

 

Skoda spec should be the starting point and that is 39psi/2.7 bar for the 19" under normal load...I assume that is what it tells you in the fuel flap?

Since no one said it here yet - manufacturer tire pressures are recommended for comfort, so... They are not necessarily the most correct ones.

It is obvious that a fuller tire will be more bouncy and less comfortable, but it will also be safer, as was pointed out above, more economical, handle better (if not over inflated) due to less sidewall flex and in the case of low profile tires, almost essential not to damage the rims on bumps and holes in the road.

I prefer mine to the higher side.

Also, an under-inflated tire will get warmer and increases the risk of it exploding.

I put mine back to the recommended "eco" setting today - 3 bar/43.5 psi. Actually not much more firm than 2.7 and handling does feel sharper...

 

Will see how I go...it is colder here at the moment.

Apologies for the typo - it should have said 38 psi.
