Pirelli Tire pressure

[guest12345]

What is the ideal tire pressure for the golf gti pirelli with the pirelli tires??

I have no idea how to read the sticker!!! I know how to convert kpa/bar to psi... but i don't know which ones i should use... plus the whole "R16/17/18" on the left, what do they mean?

Ps. It would usually be 2 people with the little bag...

But for more people... why is the front tire less pressure than the back tire?

thanks guys.

.

It says for 16" 17" & 18" wheels with up to 2 pax + small luggage run 2.6bar (~38psi) in all 4 tyres.

If you have a full load then 40psi front / 46psi rear as the extra load is applied more to the rear tyres.

oh cool, thanks for that information.

In other cars i have in the past, they sometimes say to have the pressure slightly higher to keep the tires for longer... is that true??

For other pirellis owners, what pressure do you have for your tires for day to day use?

Before i just went and checked the tire pressures and some were 42... some were 38... 39... and 40

So i just went to the petrol station to put it on 39Psi for all 4 wheels, is that acceptable?

Haha - I went through this exact thing the other day. At first look I couldn't understand what that sticker was saying as I assumed the 18s on the Pirelli would need different pressures than the "regular" sizes.

Anyhow - after deciding that 260 kPa was what it recommended I went to the servo and checked my tyres. They were all a little low, around 210-220 kPa so I pumped em up and reset the pressure sensor.

[guest12345]

oh really? i've set it on 269kpa (39 psi)... as i heard having a slightly higher pressure the tires would last longer... not sure it that is true.

BUT how do you reset the pressure sensor???

RTFM, this is a safety system and is covered in the manual in detail.

Take the time to read it as it contains all sorts of other useful information.

And do a search as all the tyre pressure information has been answered before.

extremely helpful, thanks!

PS. i did search the forum and nothing specifically on pirelli tyres. The manual is in the car, its not hard to simply answer a question no? a forum is to help, not to be a smartass.

FWIW, I try to run my tyre pressure a little higher than recommended, only about 2psi higher. Having a slightly higher pressure ensures a more "rounded" tyre, and better side wall rigidity, which in turns decreases rolling resistence - hence better fuel economy. It also helps to minimise the tyre flex if you were to change direction quickly. It also minimises side wall scrub which is typical with underinflated tyres especially with front wheel drive vehicles.

The downside of it is that the contact patch between your tyre and the road is slightly smaller, which results in slightly lesser grip. That's all fine if you use good rubber and the traction rating is A or AA. That's only by 2cents worth. Over to the experts....

Clearly you consider reading the manual as optional so don't go expecting people to walk you through the use of basic functions (especially when they are safety related) when you should be reading the manual. You have to go to your car (and the service station) to reset the TPMS system so presumably you can take a few seconds to RTFM.

As for the tyre pressures there is a tonne of information, I'm sure nothing specific for the pirelli's but the same concept applies and the pirelli's are nothing special.

You're right a forum is to help but it's not there for people to ask the same questions over and over again without taking the time to search for answers first and neither is it to replace the need to read the owners manual. If you do these first you will find you will get a lot more helpful answers.

And BTW the answer to your question about the tyre decal are also answered in the manual.

thats interesting, i heard something similar on the topic of having higher pressure meaning longer tyre life.

Ok, forum nazi. I've browsed through the manual, not all information is there. As i started the topic asking people with pirelli tyres, what their views were on tire pressure, which is totally different to majority of the other 'tyre related questions' as not many would have pirelli tyres.

As for resetting the pressure sensor question, you could of simply answered, "it is here____ next to ____" i don't see why you need to start up a lecture of some sort to point out people should read the manual.

Once again, i searched the forum, and there was nothing specific to the pirelli tyres, well not a heading anyway.

If you answer the questions instead of trying to control others, you would be alot more helpful as well. You going on a forum, you have to expect similar questions being asked, not everyone knows who asked what questions, not everyone check the forum everyday, not everyone joined at the same time and not everyone knows everything about cars and the car language, hence similar questions tend to be asked alot. Just because you think you know it all, doesn't make you better, get off your high horse mate. If you don't have anything constructive, why respond? you can ignore all the "stupid questions", no one is forcing you to respond.

Pirelli tyres are the same as any other tyre, you put air into them and they keep the car on the road.

Sure I could have but you wouldn't understand how it works and if you reset the system without following the instructions and than assume that the TPMS will alert you and don't check the tyres again what good is the system to you?

It's irrelevant as a tyre is a tyre for the purposes of inflation as this forum covers the Golf and that's the car you have 18's fitted to.

Blah blah blah. Clearly you can't lead a horse to water in your case..... but I'll try again and it's called the search button located in two areas on the screen.

I run 38 all round and my Pirelli is a daily driver so nothing special. Maybe you had different figures as it might have been a hot day?

[dimsim]

I have marrangoni tyres on 17's & they recommend 51psi ! IMO read your tyre placard inside drivers door & inflate to that min. I dont over inflat more than 6psi. Ive been told the cops over inflate their tyres 10-12 psi from manufacture recom.

Please describe how Marangoni recomend 51psi? Do you mean the figure embossed on the sidewall? That is the Maximum Recomended Inflation Pressure which is not the same as the recomended running pressure. Or does Marangoni have a table of recomended pressures on a www somewhere?


OP: take a valium, your dealing with Mav.

I think I'm going to buy a H1 Hummer, it's scary how many people don't know the basics about their cars and especially the tyres which are so important.
