Default Inquiry about Baleno Upgraded Tyre pressure

Good Morning!
As posted earlier,I'd changed the wheels and alloys of my Baleno from 165/80 r13 to 195/60r14 tubeless with alloys.

I'd like to know what tyre pressure to keep for daily driving over smooth and bumpy/ rough terrain and how much to keep for fast highway blasts ( good surface, mountain twisty roads)

I've been experimenting with 25- 28 psi but am worried that I'm gonna damage the tyres/ rims if i got it wrong.

Please advise. Thanks.
-Puffy.

What is your stock tyre pressure...i read in autocar india that if you upsize your tyres its better to increase the pressure a bit. The stock pressures on the accent were 30 psi all around...but when i changed the tyres from 175/70R13 to 185/60R14 i was running the pressure higher at 33psi front and 30psi rear on rehaans advice after the amby valley drive.

Now in a few days im getting 205/50R15...so should i increase the front pressures a bit more? Need to keep a good balance between ride and the wearing rate. Rehaan or any other tyre expert you listening?

32 in the front and 30 at the back seems to be the best option. Above 32 will be too high.

A friend of mine here uses 30 on all tyres. If you feel it is too hard I would suggest atleast 28. Lower than that is dangerou sfor your new rims too.

That's too low for the Baleno. Don't go below stock, which is 29. Try between 29-32.

I recently, about a month abck ,went to 30psi on all tyres, from 29
Havent really noticed any chgange in the ride. so am sticking to that , was toying ith the idea of 31, but havent gobe there yet

I'm running 195/60 R 14's

PUf i woul suggest you bare minimum stuck to 29psi at the very least. with a lower profile you should be running a slightly higher pressure than reccomended

Talk about overkill!!! Good to see Rehaan finally managed to make you fill air in your tyres. So this time they should last you longer!

Rt there are reasons for the overkill here hehe. Apart from that im getting the box as well...so have to keep those 3rd gear wheelspins in check as well.

I have a slight disagreement here..

.I have clocked nearly 5k on my new tyres..generally used to keep pressure @ 30-31 psi on all 4 (185/65 R 14 Goodyear Eagle NCT5) .. I have realised that my front tyres are loosing tread from the centre...while the sides are spankingly new...this ..at least to me shows that 31 psi is too high for Baleno with wider tyres..since this is the pressure recommended for an OPtra on the same tyres...the Optrs...BTW is 250 Kgs heavier...
I have now shifted to 27 psi...and the ride is more comfortable...no noticeable change in FE though...and the tyre wear (I hope it is not my illusion) seems to be more even...

Buffetfan, if you are noting extra wear on your tyres from the centre,then you are are right, your pressure is too high.
However i fear you are making the same error in converse by dropping below the reccomended pressure, that too on a lower profile tyre. and are now running them under inflated. Suggest you stick to 29
(unless you are trying to run under, so the tread wear will even out )

Was using Stock baleno 165/80 R 13 tyres and air pressure of 30 Psi on Bridgestones..
the ride was a little harsh..

I have decreased the tyre pressure to 28 psi ( 1 below the recommened 29psi) - the change in ride qualiy is amazing. The car seems to stick to the road now and feels much much more comfortable.

Maybe it's a good idea to keep the Baleno underinflated.

Haven't checked any FE effects yet. Although there was no discernable difference in the pickup.

surprisingly, all the air pumps are not calibrated to the same scale ... so, its best to stick to one pump and check the pressure after u've tanked up or something. i go to the shell petrol bunk on lavelle road and keep the pressure checked/maintained at 34 psi in the front tyres and 33 psi in the rear.
probably out of topic, but any idea when one should rotate (swap) the tyres? i've done about 3k km.

I too have put these tyres on my baleno. This is the same size/brand of tyres provided for current vxi model. The manual has almost a page devoted to instructions regarding tubeless tyres (sep 05 print, page 9-20). Recommended pressure (in specs chapter) is 1.7kgf/cm2 (24.2psi). They have also mentioned that for "continuous driving at high speeds", pressure should be increased by 5psi above recommended. Therefore, for this car/tyre combination 24-29 psi is the MUL recommended range! above 30 may be too high... I had no idea about it when I upgraded stock tyres, and put 29psi (recommended for lxi stock tyres) which happens to be within the range.

Any idea why we need higher pressure for higher speed? my guess is to reduce chances of alloy damage, should it badly hit a pot hole or bump. Are there other reasons too?
