25 psi is indeed the Maruti recommended pressure for the 185/65 R 14 tyres that come with the VXi.. I used to keep 30+ psi and now my car is about 20000 kms old (185/65 R 14 Goodyear Eagle NCT5) and I notice more wear in the centre of the tread compared to the sides. It is not very significant though and my tyres will probably last another 15-20 k at least.

So now I keep 26-28 psi....and just to add...no difference (no noticeable difference at least) in the FE figures that always range between 11.5 to 13.5.

In a baleno if you migrate from 165/80 R13 to 175/80 R13 should you increase the tyre pressure or decrease it ?

Anybody has a clue as to what would be the correct tyre pressure so as not to over inflate or under inflate the tyres?

why would you migrate to 175/80R13..it is wrong upsize...correct one is 185/70R13 or 175/70R14 (if you want to stick to 175 width)

To increase the ground clearance...

Exactly!
marginally increases the height plus and the contact patch.

also there would a great increase in ride comfort and not at the expense of anything .

If you travel with a full boot and try negotiating the air-port parking lot speed breakers then you start appreciating the increased ride height.

Default The real way to increase ride height

Increase of ride height is a serious endeavour, which involves suspension changes.
Typically stiffer, taller springs. Granted that bigger wheels and/or taller tires can help too.

But in your specific case, you are barely achieving an increase in height of
7 mm = 0.7 cm = 0.27 inch.



This is miniscule and not enough to prevent your speedbreaker mishaps.

Hey ram...!!!!

The case u have taken is a different one....

Abhijit has upgrade from 165/80-13 to 175/80-13

Overall hieght of
165/80-13 = 297.1mm
175/80-13 = 305.1mm

Even then the ground clearance has only increased by 8mm.....But i've seen this upgrade on cars preventing them from speedbreaker mishaps.....
I've a doubt here does tyre pressure variation help in this case????

Tyre pressure variation will change the ground clearance by a couple of mm too!
For example: Consider the case when a tall truck gets stuck in a railway underpass. The truck's crew let a little air out of the tires. This reduces the overall height (and ground clearance) of the truck and gets it unstuck.

Just consider one fact... when I changed in my Fiat uno from 145/80R13 to 155/80R13 (did not know a thing abt tyre sizing then and went with what the tyrewallah suggested). I faced two problems..

1. On full lock the tyres scrubbed against the wheel well
2. A More serious problem... and since I drive hard...realised it easily.. the body roll of the car increased!!! maybe due to the increased clearance...
In my view the Baleno is an OK handler.. not in the league of Ikon.. and increasing the GC will make the handling worse..of course if that is not so imp to you then go ahead and do it...you might have to face one of the two issues that I faced...
Of course the uno is no longer with me now..only the happy memories (first 3 years of onership) remain!
