PHUKET: -- A teenage woman was injured in an accident on Thepkrasattri Road at about 8:15pm last night, when a pick-up truck spun out of control on the slippery road, hitting two motorbikes parked on the side.

Krittiya Kengreng, 19, a passenger in the pick-up truck, suffered injuries to her right leg and forehead. Rescue workers rushed her to Vachira Phuket Hospital, confirmed Lt Sunan Pechnoo of Phuket City Police.

“We found a badly damaged Toyota pick-up truck and two motorbikes on the ground at the scene,” Lt Sunan said.

Again Thai women,big truck,wet roads,low tyre pressure? Accident waiting to happen.tyre pressure is as important as tyre tread.in the uk the police would be all over the motor,insurance,mot,license,anything defective,speeding and most of all drinking.

I'm of the opinion that low tire pressure creates better friction, not less.

Too much pressure can cause skidding easier than too little.
Just my opinion.

I must have missed the part saying his tire pressure was low.

Sorry just noticed she was the passenger.driver? Who knows but it looks like she never wore a seat belt.

You seem to know everything. Well actually you know pretty much nothing it seems. Just trigger happy to senselessly rant a bit?

Regarding the tire pressure: As mentioned by fiddlehead, low tire pressure actually increases friction and therefor grip due to the increased surface area of the tire that gets in contact with the asphalt. It increases tire wear though.

People like you are dangerous on the internet. Driving with low tyre pressures in no way increases grip, think about it, would a tyre manufacture produce a tyre that performed better at incorrect pressures.

There are disadvantages, like tyre life, heat etc., but in principle: lower tyre pressure increases grip.

Having seen many over here just keep pumping air into pickup tyres until they think it looks right or check it with a kick to the side wall I would say that anywhere near the proper pressure is probably considered low.

From the Michelin website.

ROAD HOLDING

With under- inflated tyres, the vehicle's steering is less precise.

If a bend can be taken at 62 mph (100 km/h) at a tyre pressure of 29 psi (2.0 bar), this speed drops to 54 mph (87 km/h) at 15 psi (1.0 bar), or about 8 mph (13 km/h) less.

Lower pressures = worse road holding

AQUAPLANING

If tyre pressures are 30% below the recommended pressure there is a sharp increase in the risk of aquaplaning.

Lower pressures = higher risk of aquaplaning

BRAKING

In addition, tests show that braking distances from 56 mph (90 km/h) to 43 mph (70 km/h) are 40 metres at 29 psi (2.0 bar) but 45 metres at 15 psi (1.0 bar), that's 5m longer.

15 psi (1.0 bar) under inflation = 5m longer braking distance

As I said, there are disadvantages. You claimed lowering the tyre pressure does not increase grip, which is simply not true.

What do they do at the drag strip...they lower the tire pressure for better traction at the Christmas tree.

So you are saying the mechanics and tyre specialists decide on the correct tyre pressure to run, and then lower it ?

It's good to remember that this time of the year the roads are very slippery when it rains. Lots of accumulated dirt and oil on the roads, which has not been washed out during the long dry period.

Obvious to experienced drivers ....

Not so obvious to the average Thai driver ...

Here is a flight of fantasy, teach all drivers how to drive and teach them how to get out of a skid

Slow news day?

Wonder how it was to be a journalist and resident here if for one simple month, no road accidents, no I have bigger P....... than you brawl, no suicide, no restaurant burning down, no new road project, now new buy of plan villa promotion etc.,

Got to love the tire pressure debate.... Adding to the mêlée.. If N2 is used would the pressure remain more consistent and last for longer or less ? (ok ok - don't go there... !)...

On Topic:

Speculation - this seems like a simple case of someone driving too fast in the wet !... Thats really it.

We could go more into it - i.e. wet road, pickup, no weight in the back, rear wheel drive, greasy road due to fresh rain after a dry spell....

But really, its just poor driving... no real surprised there.

If you heavily underpressurize a tire then yea, you will run into issues. This is obvious if you consider the extreme: a flat tire. But running just low pressure (a few psi under the rated value) increases traction. The examples from Michelin are 50% underinflated in two cases and 30% in one. That's HUGE. If you run way too low pressure then your vehicle will start wobbling around (road holding), have issues with big water patches (aquaplaning) or bad breaking. The tires might get also so hot that they drastically lose traction. The fact remains: a bit lower pressure increases traction under normal circumstances which is why amateur racedrivers usually underinflate the tires a bit.

Rule of tump: try to always inflate tires to the manufacturers recommended values under normal circumstances.

Note that there are pressure ranges under which tires can perform, not only one value. The pressure inside tires actually changes a lot during operation as the heat up.

Amazing you can tell she never wore a seat belt, were you actually there, or like so many,on TV, only GUESSING.

The thais are actually putting too much airpressure in their tyres.

watch some drag races and you will see. They don't call them wrinkle walls (slicks) for nothing.
