Looking for advice to buy portable car tire inflator

[Rhiannon12866]

25. I've had to add air to three different tires in recent weeks, I was told that it was the weather

And my brother told me yesterday that he's experienced the same thing. But I brought my car to the dealership last week for service and an oil change, they rotated the tires but didn't let me know that anything was wrong with any of them. The issues that I seem to have with cars are tires and windshield wipers and I did have to get my wipers replaced, yet again.
