Heavy loads or towing puts an extra strain on your tyres. So if your vehicle is fully loaded with passengers and luggage, the general rule is to add 28kpa (4PSI or 4lbs).

At high speed, (defined as driving at 120km/h for over one hour), your tyres will wear out twice as fast as when you drive at 70-80 km/h. If your tyres are under-inflated by twenty per cent tyre life can be reduced by thirty per cent. The rule here is to add 28Kpa (4PSI) from your Minimum Compliance Plate Pressure. Don’t inflate your tyres above 40 psi or 280 kPa. When the tyres get hot from driving, the pressure will increase even more.

so according to this,atleast 4psi should be increased at expressway speeds

hey another new problem created by the driver guys is to insert tubes into tubeless tires !!
Im serious ,this is done because it is far cheaper to repair a punctured tube than a punctured tire. This is also ,in my opinion a major factor contributing to the tire bursts since the tubeless are simply not designed to operate with a tube within them.
I ve seen this modification on a Chevy Optra. Its a growing trend amongst drivers since most cars sold today are with tublless tires.

Default Highway Tyre Pressure

The sumo and qualis taxiwalla's are the same... they think that if they inflate the tires up the average of the car will increase.... though not giving any thought to what the concequences would be.
GR8... it was a family in their own car!! Really sucks
As per Bridgestone the tyre pressure should be increased for continuous high-speed highway driving. This is taken from their website which has a pdf file called Bridgestonedatabook_2005.pdf. I have a copy if anyone is interested.
"7. Inflation Pressure
Car manufacturer’s tyre pressure recommendations should always be followed and can de found in the car manual.

Most tyre trouble is caused by incorrect tyre pressure. This seriously affects driving performance and tyre life.
  • Measure and adjust pressure when the tyre is cool.
  • For continuous high-speed highway driving, increase tyre pressure by 0.2 to 0.3 bar (3 to 5 psi)."

Its not the number of people who are legally supposed to be in the vehicle thats important. The driver shoudl be driving sensibly and speeds of 100 with 10 paseengers I guess he was on a speed run!!

Sad that such an incident happened. God help those drivers who drive this like this and the passenger who are inside them.

Vincentt. thanks for the info and the bump.. I read in the papers the other day that the courts have now banned luggage being carried on top of vehicles i e on carrier's.. but lets see how effective our police is in enforcing this ban...

Maybe this does belong in the tyre section, but current radial tyres in our hot conditions, do not last for more than 4 years, irrespective of the mileage. The sidewalls become stiff and inflexible and results in too much friction between tube and tyre, resulting in burst tyre.

And yes most drivers and people are under complete misconception that for highway driving pressure must be lowered by 2-3 psi. They reason that due to heat and load, air pressure will go up so pressure must be made lower. This is completely wrong and psi must be INCREASED by 2-3 for highway driving. If pressure is less, there is increased friction between sidewall and tube which finally results in localised overheating and burst tyre.

Inserting tubes into tubeless tyres is done in an emergency, if roadside fellow has no clue how to correctly repair tubeless tyre. However, at the earliest, tyre can be taken to auth./good dealer and repaired back to tubeless.

sandeep108: thanks for that lil bit of info. had been reducing the pressure taking the trusted petrol bunk fellows advise all these years! fortunately nothing major ever happened and ur theory does make more sene.
The owners manual doesnt mention anything about tyre pressure on long drives though...they ought to!

Actually reading on that tyre pressure thread (should be made compulsory reading for all newcomers to team-bhp) indicates that the plate tyre pressure as indicated is minimum.
