Tyre pressure

@sungoa, picture on the right shows the tyre bulging out..

 

Yes slightly.

 

Is it front or back wheel ?

If its front there will be a slight tyre size diff , you can do any as its engine weight. Even though you fill correct psi It will be common in all cars.

Its better to keep the recommended with +1 or 2 , think the car/tyre would have tested a lot on diff vehicles and FIAT would have given correct psi because FIAT wont disturb the comfort inside the car

 

I don't know since the picture I got from net. The tyre size was 235. On our tires there will be slight bulging since they are of lower width.

 

What should be the ideal pressure for front and rear for 185/70 R14 tyres.

 

31 psi is the correct pressure mentioned on my emotion. I don't know whether one has to change the pressure when go for tyre upgrade?
royj use 185/14" for his punto emotion and probably he can clarify this factor.

 

Tyre pressure - new car

Hi

After a goa trip (not by car unfortunately, car was new so wanted to gain confidence driving it around first) i filled 36/33 in the front/rear tyres on 21st August 2012 and have driven it in Mumbai city since. During the massive rains last week i was stuck in traffic and while moving ahead heard a distinct noise from the front left tyre. A motorcyclist indicated to me that the tyre went over a glass bottle which was on the street. I drove around but have been checking the tyre pressure since then regularly (digital tyre gauge purchased through ebay).

Today (2 weeks have passed since the air fill up) front left tyre shows 33.5; front right - 34; rear tyres - 32.

Is this okay ? should i be worried ? What do i need to do ?

 

Went through all 9 Pages and understood the following . Please correct me if i am wrong!

Maintain tyre pressure as recommended by fiat [we can find that on the driver side when the door is opened].

Warmer tyre might give a excess PSI measurement, so to maintain 32 PSI, if you the car is driven [tyres are not cold], fill for 34/36 PSI.

All the above is for Fiat recommended tyre sizes.

I am using a different sized tyre. What should be the tyre pressure[Cold] for 205/45/17 tyres?

 

You can stick with recommended tyre pressure for city drives... or when you might not touch speeds beyond 60 to 80...

But for highway drives, Bridgestone site recommends increasing the pressure by 5 psi (0.3 kgf/cm2) than the recommended inflation pressure.

I have seen this work in practice. Most of my drive was on highway. Initially I was maintaining the recommended pressure; after 30000 kms I found that the shoulders of the tyre were worn out but the center portion of the tyre still had good-life. And driving with such tyres were difficult.
Then I changed to new tyres and also came across this tip and followed it.... after 20000 Kms the tyres had even-graining and I assume that I will get much better tyre life.
Not to say, the torque, cornering and braking was only improved.... only downside is the slight increase in noise and bad roads are not filtered-off.

Also somehow I could not find the difference between filling when the tires are cold or warm. There is a petrol bunk very near to my in-law's place.
Early morning I have gone there fill up the recommended pressure; then went out for a 50 kms drive; then came back to same bunk and rechecked the tire pressure and it had not changed!!!

So the choice is yours....
