Do these guys just pressurise tyres to a 'one size fits all' routine.

Have just spent nearly £400 getting 2 new 19" Pirellis fitted to the front of the Spider - anyone in the know knows these tyres don't last 5 minutes at the best of times.

I Forgot to ask the guy to check the rear pressures as I knew they needed a top up so decided to go to Tesco and check them myself, and to get my 20p's worth (everyone charges for bloody air these days, but thats another rant) checked the newly fitted fronts while I was there - 32 bloody psi!!!!!
They should be closer to 40 for gods sake:mad:

Rant over - moral of the story check your pressures even after you have had new tyres fitted!!!!!

Had my 19s fitted by Kwik Fit Mobile, great service and when I checked the pressures they were spot on so at least some fitters know what they are doing.:)

9 times out of 10 I find that the pressures are way off the mark. Like Scott, I have found that 32 PSi seems to be the standard.

Many moons ago, I had a MKII Escort and I had a couple of new(ish) tyres put on the back of it. All was well until I came to the roundabout near Risley on the East Lancs Road in the pouring rain and lost the back end under braking. Much arm twirling later I got it back in a straight line after a brief excursion onto the grass. The cause was nearly 40psi in quite skinny (by modern standards) 175s on a light car instead of 28psi.

The first thing I do whenever I get new boots now is check the pressures.

I have been using the same outfit for 15 years. They are great - I get all of my tyres from them - must have bought over 50 over the last 15 years.

If, when replacing the GTV's tyres, I say put 37 front and 39 rear they will do it. If I forget - it is 30 - 32 all round.

BTW - I have a set of Dunlops on the front which are still, just, legal and they have covered 21k miles. That's double what I have achieved on anything else.

My garage asked me what pressures I wanted.

They couldn't believe the fronts were meant to be 39psi

In their words "Thats a F****** lot". :rolleyes:


At least they asked me, instead of just putting them up to a default pressure.

In my opinion, it is YOUR responsibility to ensure your tyres are inflated to the correct pressure. I always check my tyre pressures as soon as I can get to a air pump after having new tread fitted.

In my experience they seem more interested in selling you nitrogen than actually pressurising the tyres correctly.

That's true but at least they should be in the same ball park. Mango's fitted mine (well, outsourced the fitting) and 39psi tyres were set to 30psi :tut:

Costco do this as standard. Not 100% sure if it has any real benefit or just another gimmick.
Allegedly it is because pure nitrogen has better temp vs. pressure properties than the *******ised mixture that is compressed air.

That much is true, but would you honestly be able to tell the difference in a road car? Has anyone done a Pepsi chalenge on it?

Weirdly, yes..I just had my fronts replaced and all four wheels balanced and immediately it feels much better, despite the pressure being lower than I usually have it (although well within spec).. Where can I get a bottle of Nitrogen from? (I've got some helium in the garage, do you think that'll help?? :lol:)

Helium will leak out. The atoms are small enough to permeate the rubber.


You can get nitrogen from BOC, but you will need to rent/buy a cylinder to keep it in.

my 'trust no one' approach to safety means the morning after i've had tyres fitted, i check the pressures. Almost always wrong.

When i collected my new C172, i drove home thinking 'this feels a bit wrong'; next morning, i checked it and the tyre pressures were at 28, 22, 41 and 48 (!) psi. IIRC, it should have been 32 f and 30 r.

All good fun... :)

Let's face it, you'd just be offering hits of helium to people at meets so they can sound like that singer girl Duffy.

I have several hundred cubic metres of N2 at work, but it might be hard to disguise a car tyre pumping up operation.

Last time I changed mine they forgot to balance one of the wheels (I was watching and had an arguement with the fitter when he said he had done it). They also forgot to fit back on my dust caps (probably to wind me up). :rant:

I must be one of the luck ones, I;ve been using the same guy for 12 years now, and never had a problem runs a small local tyre shop, always looks after me, always lets me have a good gander at the vehicles when on the ramp.

He always tells me what the tyre pressures should be, and then asks me if I want a dfferent pressure or stick to the book etc

I was at a party and a girl there worked for BOC, she said they'd had people die from inhaling Helium! Taking too much causing asphyxia (spelling, wheres the literate?) as it replaces the oxygen in the air and therfore your lungs!:wow:

I can speak from personal experience: too much helium will knock you out. I inhale it all the time at work (it's great for prank phone calls).

The stuff you get in balloons has some oxygen in it so it won't kill you but commercial or military grade stuff will do bad things.

PS as a member of THE LITERATE, I can assure you your spelling of 'asphyxia' is perfect.
