Car tire

[Dusty MI]

Anyone ever have a car tire loose air only while it was being driven?
We were going on a site seeing road trip, after driving a few miles the dash enchanter showed the right rear tire loosing air. We stoped at gas station and blew it back up, then went home. When we got home, I check that tire, it was low again, and I blew it up again, and put the car in the garage.
It's been a few days, I just checked again, and it's not gong down any in about a week.

Maybe it's parked in a position that's pinching off the leak. Mark it, drive it around a little and make sure it's not in the same position when you park it again.

Maybe the wheel?

What pressure is it filled to? What pressure is it now ?

There is probably a nail or something in the tire which driving it moves the nail enough to leak enough to notice. Put some soapy water in a spray bottle and go around the tire spraying it. If there is any tiny leak it should blow bubbles.

Possibly a valve core that sealed properly last time you put air in.

had a sidewall leak do that, they junked the tire.

I would say something very small in it that only lets air out when the tire is flexing while driving. I have had that happen. The soap in water with a spray bottle is what I use to find a leak. Sometimes the leak is so small you really have to go very slowly around the tire, rim, and valve stem.

I once had a tubeless tire valve stem slowly leak air while the tire was rolling; it made the valve stem wiggle in the rim hole. New stem was the solution.

Leave the valve cap off and see what happens. A valve cap on one tyre of a ex military Landrover I had would depress the valve when hot from driving .

Or if you have a small pool of water push tire under and watch for bubbles. Even a very small leak will show.

Does it have Aluminum wheels. I repair a lot of those.

I was going fishing one time. Pulling out of my paved street onto a paved roadway, I felt a funny response from a rear (drive tire) as I was making the turn. Got to the fishing spot and the tire was almost flat. Forget what exactly I did about it at the time, but later on during an inspection I saw that I must have run over a sharp rock when I felt the funny response as it cut through the cord to the tubeless interior......on a near new tire.....wasn't happy about that.

Put some soap and water in a spray bottle and spray it down, be sure to remove the valve cap and spray the valve.

Centrifugal force can be an amazing thing. Ask a pilot, or astronaut, or race driver, or crane operator.

Went to a tire shop yesterday and got it fixed. Didn't ask but think there was something stuck in it.

 

[T.R.K.]

last time I heard of that happening, it was the valve stem in a tubeless tire. On that one, centrufugical force would cause it to bend outward, and then it would leak.

My sister and her hubby live in Sedona, Az. Lots of twisting and turning and hills and mountains put a lot of pressure on the sidewalls and he constantly had tubules tires leaking. He changed to I think Argon rather than air and it solved his problem. Didn't look into the molecular structure and reason behind the change, or if Argon was what he used and why that gas rather than another.

Just to confirm. You took the time to post a question herein. Other men tried to help you, using their time. Then, you had tie silly thing fixed, yet did not bother to take the time to even ask what service you paid for. Did I misunderstan?

A small crack where the sidewall meets the thread can open up when the crack gets on the bottom as the tire flexes.

Probably Nitrogen. Larger molecules than air and not nearly as heat sensitive as air.
