The right tyre pressure?

lilMonSter · 17th September 2009, 22:23

Hi i have an alto running 175/60/r 13 yokohama a drive tires.
What correct air pressure should i maintain in them. i'm running at 28 right now. the guy who i got them from said to keep it at around 28. but i'm not sure if thats correct.

Gansan,

The difference will be minimal. If ever you have to change it then you can safely use it with 31 psi and then check it again when the tyre is cold the next morning and you should be fine.

28 psi is far to low for the Alto. It is best you stick to 30/31 psi for city drives and perhaps 31/32 psi for runs on the highway.

30-33psi is the most common range for almost every car in the hatchback segment.

30 psi would be idle for your but again it all depends on how you want your ride to behave with you ....

Coming back to my earlier query, what is the best tyre pressure for a ton heavy vehicle like Tavera? How good is Nitrogen? I have 4 new tyres. And I want them to last long! Two of my old tyres gave me 72k kilometres.

Team, please guide me on this query of mine! Right now I am having 32 and 35 psi respectively. The ride quality is better and sturdier now!

I have upgraded my stock tires to Yoko ES100 195/60/15. and currently front 35 and rear 33. i feel ride is bumpy. should i lower the pressure ? but i feel as swift DDiS have heavy engine on front. MUL recommend 36 for front and 33 for rear.

U guys worry too much!!!

There is no such thing as an ideal tyre pressure. Pressure requirements keep constantly changing with road surface, load, weight distribution, driving style etc....

So keep experiementing with diff combinations for varying driving conditions.

When driving alone, you might find a certain tyre pressure is the best but the moment you have 4 passengers and luggague on board, you need to re-calculate the settings. Same goes for when you're driving for economy vs performance.

Gurus,

What is the recommended tyre pressure for Chevy Spark? 32 at front and 30 at rear, are these OK?

cuttingcrew · 14th October 2009, 22:49

Hi All,

I will be driving to Kodai from Bangalore over the Dewali weekend. My car is NHC iDsi. I hardly cross 100KM/H even on GQs. We will be 4 adults and one kid. I maintain 32 (front) and 30 (back). Is it OK for highway driving or a bit under pressured? I am a bit scared after reading in one of the threads about front tyre bursting and 90KM/H. Though mine is tubeless. Please advice.

Thanks in advance.

Hi All,
I am confused with the recomended tyre pressure for Maruti Zen and Alto.

According to Owners manual both Zen (the old model) and the Alto uses the same size tyre. Details are below.

Zen - Details
Tyre Size : 145/80R12
Recommended Tyre Pressure : 1.7 kg/cm2 (24 psi)
Weight : 750 - 765

Alto - Details
Tyre Size : 145/80R12
Recommended Tyre Pressure : 2.1 kg/cm2 (30 psi)
Weight : 740 - 750

I dont understand why there is a huge difference in the tyre pressure, where the tyre size is the same and the weight is also comparable.

I noticed it after long time when the A.S.S. told me to use 24 psi with my Zen.

Thanks in advance
Vijay

Yesterday I purchased an issue of WhatCar so I could keep myself awake on a journey to my inlawful place. There were quite a few articles on tyres in this issue. Among the advice on selecting the correct tyres, maintaining proper pressure and a very informative article on how to react to a tyre burst, I came across a couple of statements that I found interesting (meaning I didn't know them till I read them). So I am presenting them here to check if they are fact or fiction.

1. More air in a tyre helps reduce heat build up: Is this true? Does this mean by default a tyre with a 35psi pressure will run cooler than an identical tyre with 30psi ?

2. When going on journeys in excess of 100kms, always overinflate the tyres by 1-2 psi: This statement has been made in a Q&A section with some guy labelled a "tyre expert". I have been running on tubeless for last four to five years and have never overinflated the tyres on purpose. The air leakages in modern tyres/valves are too small to warrant overinflation. So is there any substance to this statement?

I always though that on long journeys the pressure increased slightly. In that case shouldn't the pressure be kept on the lower side? Correct me if I'm wrong.

I switched to alloys and changed my tyres to Yokohoma's, the installer told me to keep a lower pressure as the tire was wider. He told me 23 psi would be enough. Myth or Fact?
