I haven't gone through the complete thread as this query must have been answered. Just for curiosity and as experiment, I tried to get tyre pressure checked at 3 different pumps which are very close to one another within a matter of 7-10 minutes. However at every pump the tyre pressure was different.

Pump 1 - checked and filled to 32 psi.

Pump 2 - checked (showed 29 psi) so filled to 32 psi.

Pump 3 - checked (showed 30 psi) so again filled up to 32 psi.

How can you come to know which of the three pumps filled the correct 32 psi?

Can the experts tell me what is the correct tyre pressure in psi for 2.7 and 3.1 bar as indicated in the label below ? This is for the skoda kodiaq with tyre size of 235 55 R18. Google conversion suggests 39 and 44.96 psi which my gut tells me is too high, but i dont have any idea of this tyre size.

I think if you are usually driving with 2-3 people and little or no luggage then 32psi would be ideal for your car.

The pressure you have mentioned is when the car is fully packed with people and luggage. I’m guessing that isn’t as often hence for daily drives 32psi is good. Increase by few points if you are going on the highway with a full house.

I usually maintain 2psi points lower than the recommended as I usually drive alone or with one other person.

I was just going through the Ford Fiesta's owners manual when I came across this, how can the front tyre pressure be lesser than the rear? also under full load isn't the difference between the front and rear tyre pressure (14psi) too much? I somehow think they got it wrong, and am maintaining 35psi in all the tyres, am I wrong in doing so? should I stick to the tyre pressures in the owner's manual?

One of the tyres (front left) in my Wagon R was slowly leaking air. I sent it with one of my known driver's to get it checked. That fellow said that the air is leaking from the rim and tyre margin and can be blocked using some liquid sealant costing Rs. 300/-.

I was not convinced with that product as you can see from the snaps (Japnes) so I asked my driver to get the car back. I drove the car yesterday and found to have a lot of bumpiness and sounds from left front side. So I checked the pressure and saw this!

Since I did not purchase his product, he inflated it to 95psi! Had I not checked, the tyre could have burst and lead to a catastrophe. This is a reason why we should always check tyre pressure, especially after getting a repair or any work done on tyres.

I don't see a reason to doubt him if 95 psi air was filled only in leaking tire. Since the tire was leaking and it was not repaired, he would have thought of over filling so that it can be driven for more time before becoming complete flat. Usually this is done by everyone

If he had filled 95psi to all tires, it is a different story.

Terrible.

This is why I keep my own pressure gauge. Besides being able to check the pressure myself at home, this saves me from the wrong readings on the roadside shops. The gauge lasts for 2-3 years on an average and I don't hesitate buying a new gauge.

Why would someone pump in 95psi so that the tyre can easily maintain air despite leaking? He should have left it at 32 or at max, 40psi. He had no reason to inflate it to 95psi. If there was a tyre blowout, who would be responsible? As far as not getting the sealant is concerned, I would trust a better brand rather than a shady one.

For reference, Bridgestone tyre says that for normal load carrying of that specific tyre, a maximum of 44psi is required. 44psi is not the blowout pressure but then 95psi could have meant a possible blowout.

Hello BHPians,

Question for Ciaz owners: What is the tyre pressure maintained by you in case of a single person driving and in case of 3 people (driver + 2)? The car is Ciaz Alpha petrol MT (MY2019). Further information if it may help: my usual driving is in Gurgaon city roads.

I have also noticed the variations in readings returned by the tyre pressure gauges in different petrol pumps. On asking around, the below response seemed most sensible:
Petrol pumps have no incentive to calibrate the tyre pressure gauges as it is a free service.
To ensure that the correct pressure is filled in tyres, the best place would be the puncture shops.

Another line of thought I have: try filling air from a few petrol pumps, find one from which the FE returned as well as ride quality is consistently good. Stick to that place.

I think repair shops usually fill more air to easily detect leaks but 95psi is too much. But, they should have reduced the pressure after checking for leaks. This is the reason, I have TPMS installed in the car to know the pressure of all tyres during driving. Also, I fill air at home and have pressure gauge with the pump. The difference between the pump and TPMS is hardly 1psi.

Guys, just wondering if the pressure from a spare tire can be used for blowing/cleaning like the output from an air compressor? I know the compressor would have a higher output but if the tire has say 35 psi, wouldn’t that be good enough for some quick cleaning if needed? Any idea?

A chart showing the recommended tyre pressure for cars/ two wheelers found in a petrol pump. This could be slightly more than a decade old, but is nevertheless useful.

You would have to hold the tyre, with one hand while keeping tthe pin of the Schraeder valve depressed, all the time aiming it for the compressed air to do your quick cleaning. All the best

A quick observation : I feel that front & rear tyre pressures have got swapped in the chart. Usually, engine side gets more pressure. Or ?
