I don't know what tires you have but if 65 psi is recommended & you're running 40-42 in my opinion they are considerably under inflated.
But this subject goes on forever & nothing ever is agreed upon other than everyone has different options or preferences as to what works for them & none of them are as per the official regulations.
I run the rears at 40-42 unloaded around town. I have Cooper Highway Treads with about 45,000 miles on them. No issues and wear looks good.
T&RA...Tire and Rim Association. Dang using the word RIM rubs me wrong. It's a WHEEL. A rim is part of a 2 piece wheel, like what came off a 1928 Mack truck.
OK, back to pressure washing the porch...

Not to change the subject, but here I go....

Speaking of pressure washing the porch, have you looked at one of these "doo dads" ??? I bought one for the concrete driveway and the approach ramps that are covered with snow part of the year and never really dry out on the north side of our buildings. Mold and dark algae seem to love that environment and the concrete never looks clean.

Anyway, one of these does a 14" path at a time, doesn't have any overspray to make a mess, doesn't need any chemical cleaner (for most stains) and keeps my legs from getting "gooped up with slime" from the overspray....

Between this and the short nozzle "pistol wand" it's hard for me to say which is the most useful accessory I've bought for my pressure washer.

If you "comparison shop" (something I always do) make sure the pressure rating is greater than your pressure washer output rating....

Now back to our "regularly scheduled tire debate" .....

I agree 👍
Reading 2021 Ram owners manual and it clearly states under Inflation pressure "This is the cold tire inflation pressure for your vehicle for ALL loading conditions up to full GAWR"
This was referenced from the tire and loading information placard section of the manual.

Tire threads remind me of this movie…it’s a couple of little clips with a pause in between…I’ll just see myself out now

YES! I told the son I wanted to pressure wash the drive as well. He asked if I wanted to borrow his “surface cleaner”. Heck yes. It made short work of washing the mold and mildew off. I had already bought off Amazon 2 wand extensions. One of those extensions on the round cleaner and I was waltzing around the driveway.

OK, thanks.
Not to be ugly, but I don’t care what they say, they haven’t had 3 back surgeries.

Tires, truck brands, diesel vs gas, shocks and on and on - ain't it a blast? Since we're on tires and looking for something to agree on, would we all agree that a tire at 0 lbs. psi is flat?? We all have our druthers on tires and how we run them but seems like that would be an agreed statement.....?? Sorry, time to run get shrimp.

bought one of these to do my pier and my decks..seemed like it will be less likely to blast away the wood and make it more uniform for staining and sealing

My pressure washer is rated at 3600 PSI, and my floor cleaner will "eat away at the soft wood" on my pressure treated decking. When it dries, it leaves a "rough surface" that needs a little sanding if you have "tender tootsies".. DW does, I can hardly feel my feet any more LOL...

There is no pressure adjustment on my pressure washer output, but I have an old pressure regulator that I "hitched to the pressure washer pump output fitting before the hose is attached. I found that about 2500 to 2700 PSI won't gouge out the soft wood on the decks. When I win the lottery, I plan to replace all the pressure treated decking with Trex composite decking, but that's only after winning the lottery...

with the multiple nozzles in the round surface cleaner does that decrease the pressure equally? two nozzles 1800 a piece instead of 3600?

Pressure from those nozzles is a lot like the "restrictor they call a regulator" in RV city water supplies....

The "speed that a jet of water flows from a nozzle" is dependent on two things. First is pressure and you're right, with two nozzles, theoretically the pressure would be equally divided. Second is the volume of water being delivered by the source. If the source provides more volume than the nozzles deplete from the manifold, then the pressure never drops at either nozzle.

That said, the volume of water supplied to the nozzle manifold, coupled with the diameter of the holes for the water to exit from the nozzle jets will determine how much pressure builds up in the manifold. So, depending on the GPH of your pressure washer pump and the volume flow through the nozzles, you may wind up with "max pressure" to all areas of the manifold or you may wind up with a reduced nozzle pressure from the "large volume flow through the nozzle holes (restrictors)....

Just like the "resistor regulator", if you have a lot of volume, and only a small amount of that volume exiting through "tiny nozzle holes" then you may very well have 3600 PSI supplied by the pump and 3600 PSI built up in the rotary deck cleaner manifold....

Sort of like 3 GPH @ 3600 PSI into the manifold and 1GPH out through each nozzle, you'll never see a reduced pressure in the manifold. On the other hand, 3 GPH @ 3600 into the manifold and 2 GPH out of each nozzle, then the reduced pressure would "average between the two nozzles" at a reduced pressure.....

Just like the "restrictor regulator"... When you're using water, the pressure drops, but as soon as you turn the water off inside the trailer, the pressure starts to rise until it equalizes at the input pressure which flows through the "reducer" and you have input pressure inside the trailer.

So, depending on the volume of water supplied by your pressure washer and the volume of water delivered THROUGH each nozzle, you may have a reduced pressure that's equally divided by the two nozzles or you may have "input pressure at both nozzles as the pressure never drops due to input volume/output flow.

Correct. As your friendly forum pump specialist with 35 years of experience, restricting the flow will reduce pressure, all other things being equal. We used everything from a simple orifice in the pipe to a computer controlled air actuated valve.
Back to the local Fox TV debate program..

Other than that, it's like making ice cream, as we used to say. I think our BD unit was one of the few that hasn't blown up.
