America's tire technician overfilled my tires

[jiffyjhn]

Almost a month ago I got some new continental tires at America's tire which they installed. Today my OCD kicked in and I checked the tire pressure(tire's max rating is 51), and found one of the front tires was filled to 86psi!!.
How bad is this? I've been driving in 100F+ heat for a few weeks like this, was I in danger of a tire blowing up? Should I get them to replace the tire?
Also curious what tire pressure y'all prefer for daily/spirited driving.

First off, I suggest you get a second opinion from another air pressure gauge or calibrate yours.

If your tires have not blown from that pressure, they should be OK, once the pressure is reduced.

I have found that it is not unusual for shops to overinflate tires (usually about 5 psi).

Your car should have a sticker around the door jam that gives the recommended tire pressure. The same pressure will usually work OK for both daily and spirited driving.

LOL when I first saw 86 psi I thought my gauge was broken, so I checked on 4 other ones I had lying around and they all read similar pressure.
I'm starting to think they did it as a joke to put 86psi in a 86.

I hope they didn't top off any of your car's fluids. No telling what they would have put in there.

Yes, check and make sure there isn't oil running out of your car's dipstick tube -

Brings to mind the time, waaay back in the day, when I witnessed a dumb ass pumping up a large truck tire. An older mechanic suggested he put the tire in a cage. He replied that that would take too much time. He did have the sense to place the tire with the snap ring down, however, the tire did blow and blasted the wheel and him about 5 feet off the ground. Looked kinda like this.

Probably fine if you reduce pressure down to a decent setting. Might have a bit more wear in the center on that tire but if it was only a month shouldn't be perceptible in the long run. Wouldn't go back to that location again if I were you.

Recommend to keep checking pressures every few days.

Welp, back in the day, with bias plied tires, one could just look at a tire to see it was low on pressure, then confirm that by pounding on the tire with the palm of your hand.

When radial tires came out, they always looked low on pressure (to me at least). So, check the pressure more often was a good idea.

Most newer cars come with a little figure that pops up on the dash that warns of low tire pressure. However, it won't tell you if the tire is over inflated -

Since tire pressures won't get too much over inflated, all by themselves, someone would have to over inflate them.

Back in the day, most people wouldn't over inflate tires because it took too much effort -

It must be my nap time!

Totalled, please sell car and flood used market so I may buy a used one cheap.
