Look on the door to see what psi is reccomended, i'm thinking 32-34 psi

I would say that is very high. Chalk test them if you are worried or go by what your door says. You can watch this horrible video explaining how to chalk test your tires. It's painful though. :wow:

The tires must have felt like they were loaded cement instead of air. At times the tire installer over inflates to pop on the bead to the wheel but then should adjust to normal PSI.
Each tire is different, I like a firmer tire thus I start at 36 PSI with my Wild Peak AT3W but liked 33 PSI in Wild Peak AT (older model).

Haha, yes they fail miserably at their jokes, but the video is helpful non-the-less. But man, strap anyone to a chair and make them watch the video. After the third time they will confess to anything. :lol:

Awww, it wasn’t all that painful. I kinda liked it. Ha!
It did illustrate the method, but it was not quite right.
Actually, if you’re OCD enough to run a chaulk test, you should load your vehicle as it normally is driven. All the gear, full tank of gas, passenger and driver seated. For this video he should have at least chaulk tested the DRIVER’s side where the most weight was.
I suppose you should also test EACH tire.
That could be a long process to tweak in the optimal pressure for each tire.
And you have to do it quickly before the day heats up the air, tires, and pavement.
I guess you also should do it at night for a more stable thermal environment.
Damn, I’m not going to be getting any sleep tonight!

Yep, 52 Lbs is a lot. When I first got mine home I checked pressures. They were all at 41 Lbs. I lowered them to 36 and am happy. My last 2 cars were delivered with over 40 Lbs. From past forums it seems that's SOP with Subaru for shipping but ... it should be a part of the pre-delivery set up to lower to prescribed pressures.

When I took delivery of my 2018 I installed my Scanguage 2 and when it reported the stock Dunlops were at 55 pounds I didn't believe it. When I finally checked each tire with a digital pressure gauge they were indeed at 55 pounds.
I've no idea why Toyota would unsafely overfill the tires at any stage of building and delivering the vehicle to America

When I picked up my '17 TRDORP it was set just like yours. I have a feeling they are set at the factory or port to make sure they stay inflated while the truck is in transit.
Just lower the pressure to about 36psi. 32psi is what is recommend by toyota but even dealers (here in Denver) don't suggest that. It give no room for running a little low. If you run 36 and forget to check your tires, you may drop to 34 or 32. You're still all good. If you run 32 and loose 2-4lbs, then your tire is really low.

Are the tires really supposed to be like this?
Mine (stock) 2019 SR5 came at 49 PSI?!
Today I took it down to 39 and the tire looks flat'ish. Have a look at picture. Not sure I want to take further down to 32psi - which toyota recommends (and I certainly am not trying to second guess their engineers..) So i wonder if I am doing something wrong?

All foreign manufacturers overfill tires. That makes it safer to strap them down properly during the long boat ride.
Part of the PDI (pre delivery inspection) is to adjust the psi to the setting in the door.

It is impossible to determine if a tire is low (or high, for that matter) by looking at it unless it is virtually flat.
Old school bias ply tires would look low when they were low.

Buy an ARB tire deflator and go to town.

They are members here with their 5th 4Runner and make pretty good videos.
