5. Why is it not a good idea to fill up car tires before a long drive in summer time?

Answer 1

You top off tires to their proper pressure before starting to drive (when cold), even in summer time. ~
Otherwise your gas mileage will punish you and your tires will wear faster .

Answer 2

ok lets put an end to this myth people car tires need to have at a cold sitting pressure the amount on the sidewall of the tire they are cold tested which means that they are inflated to thier pressure when they are at ambient temperature which means before you go out for a long dirve fill them to your manufactureers recomneded pressure before driving, also a car tire can withstand more pressure then what is recommended on the sidewall i wont tell you how much more because i dont know specifically for each tire but i have aired car tires up to 90 pounds to find leaks before also when a cars tire gets hot and the pressure increases it really isnt that much of a factor in it blowing out or not now if they got to the point that they had 100 pounds inthem and were hot and supporting the wieght of the vehilce then you would a have a chance of them blowing out but as long as your cars tires are set at teh manufacturers recommended pressure then they have already accounted for the pressure changes due to driving on hot pavement in the summer people do test this stuff for a living

Answer 3

Gas expands when the temperature rises. When summer comes, the gas inside your tire will expand too, and it will expand even more due to the rolling friction caused by the rubbing of your car tires to the frying-pan-hot road. When you fill up your tire, then there will be no space for this expansion, and the force of the gas expansion would try to rip your tire off and five you a busted tire.

Answer 4

It is a good idea to keep the pressure up. The tires stay hard and get better mileage. The tires will warm more on a hardday and the pressure will go up but the tires are designed to handle it.

Answer 5

The tires become a bit hotter when the car is in motion, there is friction between the tire and the road (else you would just sit there spinning your wheels!). this rise if tire temp will heat the air in the tire and hot, trapped air will cause a rise in pressure. Check out Boyle's\Charles law. Also check out your tires manufacturers web sites for ideal pressure. Safe motoring!

Answer 6

In theory, once the tires reach a higher temperature, the pressure will be greater than what they are initially set at when cold.
In the real world, this is a minor concern - under inflated tires generate much more heat and are more apt to blow out at speed. Better to set the pressures at the manufacturers' specs before heading out - safer, too.

Answer 7

You dont want to put too much PSI into them. Car tires heat up from friction on the road. The heat causes the air to expand, increasing the PSI. If it increases too much, you blow a tire. However they are built to withstand the required PSI found on the sidewall of the tire, and that is also the best PSI on your gas mileage.

Answer 8

It's not a problem. The implication is that the hot tires on the hot road will expand the air in the tires, making them over-inflated. I think this overinflation would be negligible.

Answer 9

the vehicle is junk and extremely risky at this element it really is russin roulett no longer in basic terms along with your existence yet others. Sorry hun you need to get what youc an for it and get some thing that doesn't have those issues it isn't secure to promote it to all and sundry in the experience that they plane to rigidity it in case you do promote it to some different person make sure they signal the bill of sale that staets this vehicle is for elements in basic terms so that you aren't to any extent further in charge after the sale....

Answer 10

Heat will cause the air in the tires to expand and therefore will cause the tires to blowout.
