Aquaplaning...

[jimbobsimmonds]

hi all, just witnessed a poor chap aquaplane clean off the road lucking into a drop kerb and a playing field, so not damage done! but the thing that shocked me is that he was only doing around 40mph...

so PHeaders i was wondering at what speed aquaplaning can become as issue? I know there are many factors, i would imagine a fat tyred/lightweight car would have a lot of aquaplaning issues!

cheers

Don't forget the tread depth on the tyres too...

.. and the volume of water.

Was it really aquaplaning, though? Whenever there's a wet day it seems everyone shouts AQUAPLANING but it rarely is. More often than not it's just a penis.

It's often the case that people are only resting a hand on the wheel, so when they hit a nearside puddle, the n/s/f wheel turns abruptly left, by which time it's too late for the driver to correct the car. Cue ensuing agricultural excursion.

When approaching standing water, hold the steering wheel more firmly than usual (i.e. not a vice-like death-grip, but firmly enough so that it can't be tugged away from you), and keep the front wheels pointing forwards. Job's a good 'un.

Succinctly put.

Very true. Usually just asking too much of the the tyres on a wet road.

I never know why people buy tyres based on their ultimate dry grip. On the road the wet grip is more important in the real world - especially in soggy UK!

nah, either the guy just let go of the wheel or aquaplaned... he was turning, then all of a sudden he was going in a straight line!

now the let go of the wheel comment i just made sounds plausible

I guess some people do it because they only use their cars on dry days?

Anyway, yes I agree with you, wet road performance is important in the UK.

Whenever they seem to test the real cheapie tyres the big differences in performance ( between the top brands ) seems to arise in the wet.
The dry road performance is usually much closer in all the tests I've seen

I was always told that the speed at which you can aquaplane in mph is;

9 times the square root of the tyre pressure in PSI

But only if the depth of water is greater than the available tread depth.

It's surprising how slippery these penises are. You only have to look at the number of A&E admissions where someone inadvertently slips on one in the shower and it inadvertently lodges itself in the victims anus - inadvertently you understand.

Wait a minute, I've heard of that before. I call it understeer.

It's always penises and anuses with you, isn't it?

Well one has to have a hobby and track days are becoming so expensive these days.

Seriously, bumsex is not a valid alternative to a trackday.

Well they both leave skidmarks.
