Tyre pressure

IMO an upsize tyre would need a notch less air to keep it flat on the ground shoulder to shoulder, reason being it would have a higher load bearing capacity (check sidewall and compare max load capacity). Logic being , if it is put on car which is lighter than what that tyre was intentionally meant for (which it would be since you are upsizing), it would stand a bit more upright, its shoulder being off the ground a bit.

So a point less pressure might bring it flat on the ground which is how it should ideally be.

My 2 cents....expert please advise.

 

What's that you follow Abdul? I usually maintain 32 all around, yesterday notched up front wheels to 34 and rear at 32. Now I'm noticing that the ride has become bumpy.

 

Go in for 33/34 PSI on all tyres for cold and warm weathers respectively. I have been driving my Linea with these specifications now. I have not felt anything negative in ride quality.

 

teky,

I fill up 32 front and 30 rear in Cold . It is more stable and the tyre life also seems better.

Thanks Ananth - However in the previous pages it was mentioned that Linea has a different pressure specifications due to it's weight possibly

Since it's the active version does it have the original 165/80 R14 or have upgraded to the 195/185 'ers?

 

Teky,

I have done no upgrades to my tyres .

jumu@ for oem 195 tyres recommended prs in all tyres is 32 ,why? What is ur suggestion? ATUL

 

I do recon normal air is the best for tyre life rather than anything else.

Warm tyres after 5 kms - 10kms of ripping run upto 80 - 100 kmph needs 36psi- 37psi (especially city+highway)

Cold tyres would ideally be with instant cold starts and be filled as per FIAT Recommended tyre pressure with respective models will pose no harm.
(I do 33psi in all tyres 195/60 R15 any season to avoid underbody bumps and to avoid scrapping thy protection plates)
when i was running the Stock Tornados 165/80 R14 it was sumthin like 34 psi front & 33 psi rear - cold tyres

OT : Please condemn all rumors about Ground clearence from FIAT-BASHERS elsewhere,
all FIAT cars have adequate ground clearence and hold a niche for itself in the indian automotive segment compared to XYZ brands. (DARN HAVE A LOOK AT REGULAR PADMINI TAXI's) they seldom have anything such as protection plates and still run on those flat tyres...Absouletly SNUG!
To my dismay i still havnt witnessed a Taxi Wreck caused to do less traction or low tyre inflation problems on mumbai roads since puberty hit me!!!!

Hope this helps, Happy Inflation - Drive Safe

Well said TORQUEY.

Punto should be good with same pressure on all 4, in a Linea pressure distance should be maintained coz of its longer wheelbase (unequal weight distribution between front and rear).

I am on Nitrogen on my T-jet and I am all positive about it till now. no variation in heat or cold. Ride quality alwaz remains the same in hot or cold. The car also feels lighter to drive(but it can be pshycological).

As long as there is a heavy engine in the front and the weight distribution is uneven as determined by the manufacturer who has done severe testing to arrive a the conclusion that a differential tyre presure is reqd ,it will be ideal to follow that. Even if you go for a higher pressure of your own psi , just maintain the difference between front and rear.

I have used Nitrogen and I found it not suitable mainly because you tend to forget the maintenance of tyre pressure on a weekly basis and any kind of loss of pressure tends to go on for a month and more and it is too late to realize it. I have lost a bit of tyre life on one of the tyres due to this. When on normal air I have the pressures checked every week and it helps for sure to catch any loss of pressure within a week.
