You will just hear a GBOUA sound, you know the rest.

Man! This really got me laughing my head off, I can still see people glaring at me, haha. GBOUA!

Again...you can't go by the size of a car to determine correct tyre pressure. I doubt this car in question is recommended to run tyre pressures that high, but...

My car's recommended tyre pressures are 36psi unladen, and 42psi with 4 adults on board. It's an '00 Audi A4 2.8 V6 Quattro Sport.

Does it mean you gauge your tires when there'll be people on board and gauge again when there won't be people on board?

Hello what is the psi for nissan pathfinder 98

donshaddow:
Hello house, I read on a thread about a guy who changed his tire and his vehicle refused to start.

I will be willing to give you a recommended PSI for you vehicle to ease your safety and that of other road users.

Before you go to that "Kazeem vulcanizer" and he will tell you to put 45 psi

@siena please with a tire inscription of 195/65R15 91T and my gauge of 30psi written on the car door,my tire is not well pumped until the Guage is 45.
Is it a different measurement or is the 45 as in psi?

Siena:


How do you know the tyre is not well pumped till 45 psi, when your manufacturer clearly states 30 psi is recommended?

There is something in Auto Industry called Specifications which contradicts the above post and title of this thread.

We have Peugeot 406s produced in 2001. They are all have different recommended Tyre sizes and Tyre pressures. Some came with Steel wheels, while some have Alloy wheels from factory. Some have R15, while some have R16. Some have size 195/65, some 205/60 and some 205/55. The same way they all have different recommended Tyre psi. The same goes with Peugeot 407, 607, etc.

Each Peugeot car has recommended wheel sizes, Tyre sizes and psi stamped on each. That is the way to go, for me. Pay attention to your car to learn this things, because not all free information found online serves one.

I had a serious arguement with a manager of a service bay in a popular filling station in Abj. This guy was too full of himself. Though their wheel balancing and alignment is usually good but they insist on inflating tire to 40psi. One time i insisted he does as i instructed but the guy told me "you dont know anything".

I had to show him what was written on the door and tire (inflate to 40psi max which had a corresponding maximum weight). The guy saw that as a justification for what they do. I told him max stands for maximum, and cars have different weight and pressure specifications so the warning on the tire means if a car specifies above 40psi, this tire is not suitable for the car.

The man wont have anything i said and wont budge after insisting that he should treat my property as ordered. He went ahead without my consent to inflate to 40. I told him he wasted his energy as i would stop by their gate were a road side vulcanizer is to deflate to what i want and he cant stop me.

I prefer roadside mechanics to the high end so called mechanics that always take me for a fool even when i know they are lounging in ignorance. Roadside mechanics do as ordered with no questions asked but those ones manning expensive equipment think the know all.

I guess its that new tyre/wheel balancing stand opposite Kubwa NNPC.

Siena:


If there is a brand I know like the back of my hand, it's the VAG brand.

My cars are all Quattro, and the tyre pressures differ from those of FWD models. I go by the values in my Owner's Manual, also repeated in the fuel filler flap.

No one knows the best settings for a particular model better than the manufacturers themselves. It would appear you know better than Audi themselves. I repeat - there are several factors that determine the optimum tyre pressure settings for a vehicle. Mass in service is just one of them.

Here is the inside of the fuel filler flap of one of my vehicles. This is a 2000 Audi A4 2.5 V6 TDI Quattro:

Thanks vut pleas can you explaain 'H 29 29 S' and 'V 32 30 S, V 30 30'
Cos my vulcanizer always says my gauge is 45- wonering if it's the same measuring equipment

God bless you for your contribution... Please stand by recommendation from manufacturers.

one clown put 50 in my tires over the weekend. i had to pay additional 200 to reduce them all to 35psi. Rubbish

adanny01:


I go above but certainly not 40psi

Front i usually have 32-35psi as acceptable range while back is 30-32psi.

Manufacturers recommendation or less than that the tire looks under deflated for my liking and a little effect i feel on the steering while on high speeds especially while making corners.

nurey:


The problem I noticed is when you change tyre size to be bigger, when I mean bigger let's say factory fitted is 195/65/R15 and then one upgrades to 205/70/R15 when you use the recommended of 30psi, the tyre will not be well rounded, the part touching the ground will have more flat surface hence the reason for the guys question. People guage tires when it is well round which I noticed makes the car bounce like snopp doggs pimped ride, very very bad indeed

Siena:


The portion of the tyre in contact with the road is NOT meant to be round. It is meant to have a flatter, bulgier profile. This is what provides the "footprint", so to speak. If it is completely round, then that tyre is over inflated.

The flat footprint is what provides grip. Remove that flat area, and the contact patch becomes smaller, and grip, both forwards / backwards and lateral (sideways) will reduce. That flat section you appear to have issues with is important. Even a 18-wheel rig has a flat portion where it makes contact with the road.

Over inflated tyres will:

Reduce steering self-centre effect. Resulting in more driver input to return the wheel to straight ahead after making a turn.
Cause lateral stability issues. More likely to slide sideways if a turn is taken at moderate speeds.
Cause reduced braking, braking distances will be longer.
Give a harsh, bouncy ride. More shock damage to suspension load-bearing areas of the chassis.
Increase tyre wear in the centre of the tyre tread.

205/70x15 is the wrong size tyre for the average sedan. That is the size that comes on a Toyota Hilux IF it has factory 6"x15" steel wheels.

Another aspect worth noting - a larger, lower profile tyre MOSTLY runs LESS pressure than a smaller, higher profile tyre, fitted to the SAME car. An example:

2014 Toyota Prius, 195/65x15: 32 psi.
2014 Toyota Prius, 225/45x17: 36 psi.

An Okada (100 - 250cc engine) has skinny tyres. These require greater tyre pressures than the average family sedan to be anywhere safe to ride. Typically 36 - 44 psi, depending on model and bike manufacturer's recommendation. We're talking about a bike that weighs around 165 kilos with an average size adult.

I'm beginning to see the relationship between the all too frequent RTA's in Nigeria. Running tyre pressures approx. 3-4 psi above the manufacturer's recommendation MAY not be dangerous. Running 8 psi and higher WILL make a marked difference to the way a vehicle behaves, and I'm not talking positive differences. Tyres pressures are also set based upon the sort of suspension fitted to the vehicle in question.

My apologies for digressing here, but once you delve further into why vehicle manufacturers recommend certain tyre pressures, it is difficult not to seemingly digress. Keen technicians who under the dynamics of a motor vehicle WILL however understand.
