Tyre damage always recognizable by high pressure cleaners?

Hello together, yesterday I thought to myself, I wash my new (by the way also my first) car for the first time Now was or is still on the tire a somewhat unsightly stain, which I wanted to get away with the strong water jet of a high pressure cleaner in the SB washbox. I think that I sprayed for good six or seven seconds on the stain water with the high pressure cleaner. The stain then unfortunately did not go away, so I stopped and one day after I did read on the internet that you can never spray the tire with the high-pressure cleaner, that is very bad and dangerous!!! After that I drove 15 km also on the highway and nothing exploded. Now you can imagine that I am a bit worried So one day after that I got to the car and looked at all the tires with the flashlight. The high-pressure cleaner looks like the other three, look neither bubbles nor cracks. is an 18″ Dunlop Sport Maxx and only two months old. What do you think, half as bad or like to replace the tire?
