Michelin Pilot Sport Two (PS2) 225/40/18 92Y Extra Load : Review

[Teutonic_Tamer]

good advice, 2.6 (37psi) seems on the high side, even for the exaltos  tbh
I run  2.2 (32 psi) all round
let us know how you get on ...

No - NEVER run below the manufacturers recommeded setting -which is 35psi front, and 35psi rear!

Inside my fuel flap says 2.6 bar front and rear, fully loaded 2.8 and 3.2! 

Hence I run at around 38 - 40psi.

I think on the other forum, there was a thread on different tyre pressure stickers on identical spec GITs - did you GTI come with 17s as standard?

[Teutonic_Tamer]

Finally I think running 44PSI is dangerous and I'm surprised you're recommending it. On a spirited drive I can see my pressures come up by around 4-6PSI depending on the weather, by that same reckoning, you'd be near or at the maximum limit of 50PSI and serious risk of tyre failure.

What an utter load of bollox!  I supposed you think I should get locked up for attempted manslaughter by running 85psi in my bicycle tyres!

HTF can 44psi be dangerous?  What about the 61psi in the space saver - do we have to have a 'Hazardous Substance' warning sticker on our tailgates!

The mind boggles how you can even post such statements!

I think he was talking about the maximum limit printed on the side of the tyres. IIRC, they state you should not exceed 50psi.

I think the confusion arises about the 50psi:

 - is it 50psi when the tyres are cold?
or
 - is it 50psi max (which means that potentially 50psi could be reached and breached if the tyres are say at 48 psi and then the pressure increases due to temp when driving)?

Re tyre temperatures, I'm finding it fascinating how much the tyre temps vary during a drive via my TyreSure TPMS.

Some manufactures recommend their own Psi settings.

Vedesteins must be 40psi as ive been told by the retailer.

Nope, Edition 30 comes standard on 18's.

Can I kindly suggest you actually read the full text on the side of the tyre to which that comment relates to!  I'll give you a clue - it does NOT apply to the UK or EU.

I think the confusion arises about the 50psi:

 - is it 50psi when the tyres are cold?

There is absolutely NO confusion.  Tyre pressures (on tyres for highway use, so not 'specialists' such as F1 slicks, or Dakar sand tyres, or whatever) should ONLY be checked when the tyre is cold, and at the ambient air temperature.  You can read every handbook or workshop manual on the planet, and I'd strongly bet that it will categorically tell you NOT to check (and more importantly, adjust) tyre pressures when the tyre is hot.  And just to clarify, a tyre can heat up in as little as half a mile.

or
 - is it 50psi max (which means that potentially 50psi could be reached and breached if the tyres are say at 48 psi and then the pressure increases due to temp when driving)?

Tyres are categorically and specifically designed to cope with increases in pressue as the tyre heats up - and they have absoultely MASSIVE threasholds for 'overinflation'.

The 'dangerous' scenarious which can wreck a tyre is excessive heat, and NOT excessive pressure.  And one of the primary causes of excessive heat in a tyre is too LOW a tyre pressure.

I've regularly inflated road-legal tyres to over 140psi - and have NEVER had a tyre fail due to over pressure!

Sadly, there is some clearly very serious cases of uneducated and/or 'old skool' 'head in the sand' opinions regarding tyre pressures.!!

Yes, they certainly do fluctuate - and whilst it may seem a little unusual at first, you will (hopefully) soon get to know how your tyres behave.

Rain can throw up some interesting readings, as can when the car is parked outside for a long time, and the sun is only heating up one side of the car.

Anyway, I can't remember if you answered this or not in your original post - do you have to mount any kind of receiver in each wheel arch to pick up the individual wheel sensors?  Or are the receivers all self contained in the main unit?

Exactly.  Different tyres all perform slightly differently.

And the crucial word in that above post is 'recommend'.  Tyre pressures have ALWAYS been a RECOMMENDATION - and not some absolute 'sheeple' measurement or setting.

And just to clarify, a tyre can heat up in as little as half a mile.

....Based on the data my TyreSure TPMS is displaying I've been surprised how long and not how quickly the tyres have taken to heat up. Bear in mind that I'm not ragging it from the word go.

Doh, my bad - completely forgot you had an Ed30!

I'll go and stand in the corner with the dunces cap on for 15 minutes - is that long enough?

....A reciever transmitter in each wheel with the valve and not in the wheel arch.

And that is exactly the same sticker I have on mine with factory 18"s ????  Yet there are other stickers too for GTIs????  So has VW c0cked up somewhere?  Because the load index for 17" tyres is different from the 18" boots?

Thanks - yes, I knew that your kit had the transmitters in the new valves, which get mounted on the inside of the rim - but when something 'transmits' - then there also needs to be a 'receiver' too.

So on cars with factory fitted 'direct acting TPMS' (direct acting means it measures the actual pressure, rather than uses wheel rotational differences from the wheel speed sensors) such as Renaults, Vauxhalls and Audis - they use those same valve transmitters as you have in your TyreSure kit, but they also have four remote 'antenna' in each wheel arch.  So basically, not only are the actual tyre valves 'coded' to the TPMS 'head unit' (for want of a better phrase), but also the wheels are 'positioned' on the vehicle too.
