Ah, who pays attention to recommended tire pressures? Them engineers, they don't know nothin'...
My 16 ply tires stay at a minimum of 90 PSI...I ordinarily drive at 55 MPH maximum in any weather...

I worked on A6's in the Corps. Dry weight of the aircraft was 26,000 pounds with a full load of ordnance and fuel it came to 56,000 pounds. We only had two main tires and the nose gear tires to support that weight. So I am guessing our tire pressure was more than 35 PSI. Will check with a couple of plane captains that I know for the actual pressures required.

From personal experience......It depends largely on the tires and vehicle.
With new Pilot AS 4's on my Mustang, I could drive pretty fast in some serious rain. 5 year old Hankook's on my pickup....not so much

Having been raised in the UK I have driven in all kinds of rain. Heavy rain doesn't concern me much given the right tires. However, a light shower on city streets after three weeks of no rain makes anything with wheels a greasy weasel even at walking pace, and that situation works just as well in London as it does in Vegas. BTDT.
Then there are the subtleties of the temperature while the rain is falling. I have found that even so-called 'All Season' tires fall over in the wet when the temperature gets below 40°F. Due to their mediocre performance in other conditions, I think it is more accurate to call them 'No Season' tires. When it comes to pouring rain at temperatures above 50°F, summer tires are better than no-seasons because of their optimized tread pattern.
The best wet weather tires I ever used in drizzly, cold conditions were a set of retreads made by a company called Colway in the UK. They made these for the very low end racing market and came in two flavors, red spot (sticky) and white spot (two-part epoxy). I had a set of red spots on a Fiat 131 and I could run rings around any car on mainstream tires in tricky conditions. They stuck like chewing gum on mohair.
Then there is the front versus rear wheel drive question. A properly handling FWD car* will always be more stable in the wet than a RWD car of similar weight. My old Volvo S60 on 50 series Pirellis shrugged off soaking wet conditions on the freeway at speeds I would probably not attempt in my BMW 3-series.
* Definition of properly handling FWD car: A car that does not rely on electronic stability control (ESC) to prevent lift off oversteer at even moderate cornering speeds. Too many cars of today rely on ESC as a band-aid for poor design resulting in ill handling. Lots of FWD cars were designed in Europe during the 80s that did not require ESC because they handled properly out of the box.

I did not even need to see the clip to know what that is from. Classic movie.
speaking of tire pressure and airplanes a tire from a Delta airplane. The wheel parts were being disassembled for maintenance were not attached to the plane at the time of the explosion. It killed 2 men and seriously injured a 3rd.

The AF procedure was deflate the tire before removing it from the axle. Then, that stuff doesn't happen.

Worked on aircraft for 20 years. Never heard of a tire blowing up when being worked on.
Article said the lead guy, who was one of those killed in the incident, was a retired Air Force mechanic.

The intermediate tires on my 3200# touring car had 3/32" tread at 26 to 28 psi and it often went well over 100 mph in monsoon conditions. Never saw the need for full wets. The class I ran did not allow slicks.

I always wondered why semi truck drivers speed up in heavy rain.
The harder it rains, the faster they go. I have seen this many times.

Way back when, I remember many a hot summer days sitting in a cruiser alongside the highway, watching a thunderstorm moving in, knowing odds were good I would be responding to a MV accident within the next 15 minutes. I even knew pretty much which exit / off ramps it would be.
That hot pavement releases a lot of oil when the rain first starts. Especially off ramps that see a lot of truck use. Slick as ice. Combine that with an exit ramp with a short approach, then a sharp, decreasing radius turn....

I think they maintain the same speed. Everyone around them slows down. The driver in a tractor trailer is usually above most of the road spray. His visibility is most likely better than yours. Nowadays most commmercial vehicles are governed at 65-69 mph. This explains why they get hung out in left lane and can’t get around another vehicle on a grade.
Excuse me if I ignore the equivalent of a federally mandated warning label.
How can the auto manufacturer account for multiple tire brands with different specs?
I've gotten max mileage and handling by reducing the tire's max p.s.i. by 10%. YMMV

Had forgotten about how we worked on tires in Vietnam. Duce and a halfs had the old split rims that could/ would kill or maim one if rim blew off. We had no cages so simply turned tires upside down with rim on bottom. Attached air line and stepped back 10-15 feet until we heard the “ lock” . Also remembered my Dad telling me of one of the then new rubber tired logging machines tires hitting a stump in the woods knocking the rim off and rim cut down a small tree. Think what it would have done to a man…

You can always use an online calculator. There's one for everything.
