Title: The source of all my Handling Problems
Post by: Anonymous on March 13, 2004, 16:08
About two weeks agoI was at Tesco Express today and noticed that they'd installed a nice new and shiny tyre pressure gauge, it was digital as well.

I went across today with the '2 and thought well lets just double check the pressures.

The fronts were running at 15 PSi and the rears at 21   s:shock: :shock: s:shock:    s:shock: :shock: s:shock:    s:shock: :shock: s:shock:    s:shock: :shock: s:shock:    s:shock: :shock: s:shock:  

The rears are now ack at 32 and the fronts at 28

Its a different car now.......hood down in the sun and LOVING IT   s:D :D s:D    s:D :D s:D  

I am once more in love with the '2   s:D :D s:D

Probably handled similar to a boat before then?

Must check mine on that subject, new car - dealer probably got them on 60 all round

Lol yeah....know what you mean.

I just gotta say i am the HAPPIEST man atm.

All it'd take is for West Brom to win on TV and that'd be wicked.

Never trust a petrol station guage! Not only do they all read differently, thus giving you no comparison at all between different air-lines, but they are calibrated very infrequently, and even then can have hysterisis and linearity errors that can be as much as +or- 15% of the reading. (Trust me folks, I do this for a living  s:wink: :wink: s:wink:  )

You've said yourself how sensitive to tyre pressures the '2 is, so do yourself a favour and go and halfords and spend £15 on a tyre pressure guage. It'll be more accurate than the petrol stations own guage, and even if it is slightly wrong, it'll always be wrong by the same amount. This way you'll have consistent handling regardless of where you check your tyre pressures, and you'll be able to experiment with slightly higher or lower tyre pressures knowing you have a constant datum point.

(It also has the added bonus that your car is less likely to surprise you on a wet corner and spit you backwards into a hedge...)

just check my pressures

front OK
offside rear at 29 instead of 32
nearside rear OK

amazed at the amount of difference

is there any 'stay warm inside the car' auto sensors

inside the wheel sets if so how much

ANY IDEAS

(being lazy again sorry)

I have some of these..they're a really effective visual aid, warning you if the pressure drops below 2psi..

Haha no ! someone else asked that when I posted originally.  I have had my VVTI badges swiped...

And also on my old 206GTI someone nicked the dust caps of my Kahn alloys..which were £10 yes that much each dust cap!

There's also a really fancy electronic gadget you can get (I think it's made by Goodyear, but I could be wrong) - they put a strap & sensor around each hub, and then the in-car display shows the pressures via wireless telemetry.. Apparently very good, and the added benefit of being able to see the 'running' pressure (i.e. when the tyre is being used) and static cold temp.

Not cheap though - £250ish if I recall, and I think most branches of ProTyre / Micheldever are dealerships..
