A Catholic shouldn't assign supernatural meanings to natural causes. That is the very definition of superstition.
If your tire went flat, it means that a sharp object penetrated it, or that your tire tread wore too low and the tire was ready for replacement. If your tire went flat, it means that you need a new tire -- not that God is displeased with the destination from which you were leaving, or to which you were going.
Any good Traditional priest would give you the same answer:
"Hey, Father. I have been having chest pains. What is God trying to tell me?"
"I think God is trying to tell you to go see your doctor, my good man!"
or
"Hey, Father. Can you bless my car? It has been shaking a lot every time I apply the brakes."
"Sure, my son, but only if you promise me you'll take it to a garage to have the brakes looked at."
Catholic priests represent the true God, and serve the truth. They are eminently practical. There is not the slightest friction or strife between the Truth/Reality/Science and God and His religion.
Remember, our religion is NOT superstition. And our priests are NOT charlatans and frauds, unlike the protestant ministers, psychics, shamans, and witch doctors that exist out there to siphon a living off of unsuspecting, ignorant dupes.
If your car broke down in some way, likewise there was probably a natural explanation for it. Mechanical parts of a car fail on a daily basis, all over the country. Brakes, transmissions, radiators, hoses, starters, batteries -- you name it.
Not to say that God doesn't intervene sometimes, but when He intervenes, there's no mistaking it. Protestants constantly attribute God to things that are merely natural -- because those pathetic nincompoops don't HAVE any REAL miracles! They have neither saints nor miracles in their false heretical sects. They're desperate for anything more interesting than the common and the ordinary. For the desperate, even a strange coincidence will do!
If you were thinking and praying to God, "Maybe I should sell my house and move closer to a large Trad group with daily Mass..." and then a young couple knock on your door out of the blue, asking if by any chance you'd be willing to sell your house (even though you have no for sale sign, and your house wasn't for sale) -- now that would be a sign. Especially if they said they wanted to buy this house badly because it's close to the church they attend and that church is important to them.
