Why car tire deflates only while driving on free way?

Question

The front tire on the driver side deflates only when I drive on freeway, in other words, while going on or above 65 miles per hour. When I drive locally, it never deflates. For example, I filled the tire with air and had been driving it for more than a month now. It was perfectly fine. But, within an hour I started driving on the freeway, it deflated. This has happened twice already. Is it problem with the tire or some other problem?

Answer 1

You have a nail oe something in the tire. tight fit and only leaks when tire is moving to move the foreign object which in turn lets out a small amount of air. thus going down the freeway the tire is going around a lot more and is therefor more noticeable.

Answer 2

When you are driving in faster speeds, the tire gets hotter and air expands and making the leak hole bigger. That is possibly the closest explanation I can think of. Take the tire to the shop and check for leaks. won't cost you more than 20 dollars unless the rim is bent.

Answer 3

when driving on free way it will get hotter than normal ,so it will probably be leaking round the bead good luck34
