so you think you know about driving...

well its caused a few arguments in this office, 34 to beat......

I've just done the test, and lets just say that the results were very interesting.

Here is one of the questions I got wrong. What do you think the answers is?

On which TWO occasions might you inflate your tyres to more than the recommended normal pressure?
 
Mark two answers  

A. When the roads are slippery
B. When driving fast for a long distance
C. When the tyre tread is worn below 2mm
D. When carrying a heavy load
E. When the weather is cold
F. When the vehicle is fitted with anti-lock brakes

B & D

[Andy Zarse]

35/35 on the bike test and 28/35 on the lorries. And I haven't got either licence.

[Ballast]

well done ecurie,

But why on earth would you over inflate! At high speed the air temperature inside the tyre increases and leads to an even higher pressure!

That dont make no sense.

Who said anything the Govt did made sense?

This was a serious problem for the gopeds.

The translation of "do not inflate to over 85psi" became "inflate to 85 psi", so when left in a hot tent the tyres pop.  Allowing for this, punctures, bent brake discs, accidents, broken pull starts etc there was only one goped working at the end of the week, and then only because it had been parked up most of the time for not having its airworthiness certificate.

We'll be back in force with Kevlar tyres, carbon discs, electric start, stabiliser wheels etc next year

Done and passed all of them for real and i have the bill to prove it robbing bar stewards.

Passed all four first time only dropped one mark on my motorbike theory test andthat becasue I went back and changed it from the right answer to the wrong one??? should have gone with my gut instinct

[Lawnmower Man]

Trie all th etests and failed one of the lorry ones.  

[Perdu]

I think some people should read their own cars manuals

All the ones I ever read gave reasons B and D as times to increase (slightly) the pressures in their tyres.

But even SAAB don't actually tell you why...

Any tyre engineers in the house.

Maybe sidewall deformation is kept to a minimum at higher pressures, frankly me deario, I just don't give a durn!

If I run higher pressures and have failures I get somebody to sue when I gets outa me plastercast... If!

 

[Lawnmower Man]

Hell this is sad I'm getting too serious and it's only two weeks ago.

B.  The extra Pressure will make the flat spot smaller and so the tyre won't get so hot.
      Thus there is less chance of a tyre failure.  

D.  The extra pressure returns the tyre to it intended shape.  Agian this reduces the         amount of tyre on the road and so the tyre will run cooler.

Just make sure you're not running on Michelins

I would seriously fail my driving test today I think.
