Hello,

             

             I run a  2017 fabia state tsi SEL 110 on 16 inch tyres.   I am a great believer in having the correct tyre pressures for any car I have owned.  The plate in the fuel filler cap says 2,2 bars all round  on 16 inch tyres for normal use so 32psi. I cannot find any other source that says 2.2 bars. I have checked on Briskoda (of course) and have been on a lot of websites that invite you to find your tyre pressure. I have rechecked by the fuel cap and it definitely says 2.2, I didnt imagine it. The sites I have looked at all say 2.1 bars all round or 2,0 bars all round and some say 2.0 bars at the front and 2.1 bars at the rear.

 

             I do realise that tyre pressures are always going to be a subjective matter. Some people will tweak them up or down to get better fuel economy or better performance or a combination of the two. Even so it does seem a little strange to me that not one source confirms what is on the plate of my car.  The handbook refers you to the plate and there is nothing on the sill about tyre pressures.   I even wondered if the 4 cylinder 110bhp cars have a different tyre pressure to the 3 cylinder ones because the former weigh more than the latter and need a higher tyre pressure? Mine is the 4 cylinder  1.2.  Just a thought.

 

             It wont be the end of the world if this remains a mystery but I thought that posting it on Briskoda might shed some light.

   

              Thanks.

Sorry but what is the mystery?,

 the recommended pressures are on the fuel flap and that fuel flap was fitted at the Skoda factory.

Are your tyres 215/45R16? These size tyres have a load index of 86 (530kg) when inflated to 3 Bar (44psi).

 

32psi all round sounds about right. Does the plate give separate tyre inflation pressures for a lightly loaded and a heavily loaded car?

 

For a lightly loaded car without rear passengers and heavy luggage, I would try 32psi front and 29psi rear. Maybe upto 35psi front and 38 psi rear for a heavily loaded car.

 

215/45R16 might be V speed rated. So up to 150mph capability when the correct tyre pressures are used.

 

If you use the 32psi recommended pressures front and rear and had a fully loaded car, the tyres shouldn't fail by overheating even if they are technically overloaded as you won't be driving at more than 70mph on UK roads. If you drive at speeds approaching 150mph you will need to make sure that your tyres are fully inflated or they will get hot and start to delaminate (ie. fail).

 

Many people are driving on the roads with underinflated tyres, and unless the it's more than about 20% underinflation they are unlikely to fail when a 150mph speed rated tyre is driven at just 70mph.

 

It's always best to visually inspect your tyres before setting off on any journey to check that they are not very low on air pressure. Tyres can pick up slow punctures, and a visual inspection is very useful in these cases.

Normally H rated, as Skoda recommend. Although, V's would be fine of course, as above recommended just keep away from anything lower 😎 Same goes for load index (86 recommended, but higher should be fine)

 

I'd stick to tyre pressures in the fuel filler cap. Keep in mind, it has different pressures depending on load

So you have the car manufacturer's recommendation. The only reason I can see for using a different pressure is if you get an under or over inflation wear pattern at that pressure on tyre brand X.

I noticed on my last service at the main dealer that they set the pressures lower. I reset at 2.2 bar as per manufacturer's instructions. 

What fixed irregular wear on mine, was having the control arm rear bush replaced with a polyurethane one. It's not an easy job and requires a re-alignment of the steering afterwards. But it stops the flex caused by acceleration and braking, the tyres stay on the correct alignment almost 100% of the time, rather than only when cruising.

 

I generally prefer to keep my tyre pressures a little higher. I've tried 30psi and 35psi, on 215/45 R16 tyres, and there was no difference in ride comfort between the two pressures, except that at 35psi, it improved handling noticably in the dry, and even moreso in the wet.

 

I have my new 215/40 R17's at 35psi (though it does recommend a little higher pressure for the lower profile tyres, presumably to protect the alloys). They're louder and slightly harsher than the 16s, but that could easily be due to the fact that Dunlops SP Sport Maxx is a known loud tyre, and the Avon ZV7's i had on the old wheels are a very quiet tyre.

When i get through the remaining tread on the tyres that came on my new alloys, i'll be putting Avon ZV7's on again. Unless i happen to win the lottery or something, then maybe Michelin Pilot Sport 4's (not 4S, just 4).

My first thought was also, use the pressures in the filler door. Remember that other online sources might be referring to a slightly different model than yours. At the end off the day it's the mass of the car that matters, so even added options could in theory mean a different pressure.

 

On this and our previous F3 there are pressures listed inside the flap for comfort and economy, as well as heavy load. The comfort difference between comfort and economy can be felt!
