Hankook Dynapro AT2 psi

My new/used Tundra came with these new tires. Max tire pressure says 51lbs. My trailer is the single axle Hideout. 4K lbs. with a 500lb tongue Weight…I think. Wondering if running the full 51lbs is the recommended. Thanks for the advice…this is all relatively new to me.

You shouldn’t need to run them at 51. With only 500 lb of tongue weight you also don’t need a weight distribution hitch, but a single axle trailer can get squirrelly. You’re kind of in catch 22 spot with those. You could use a WDH with sway control to help with stability, but that will remove even more tongue weight which will cause the trailer to be less stable. Best thing I can recommend, play with the air pressure and see what feels best. You may find a happy medium somewhere.

Tony, while I agree with most of what Brent says, I'd keep the rears at the 51 pounds. I believe that year Tundra has a maximum hitch capacity of 500 pounds and you've obviously gotten to that point or more. With the 'tail wagging the dog' that comes with a single axle trailer, I wouldn't let the sidewalls have any more flex than necessary.

I guess I should have asked a couple questions before answering. I get too used to a 3/4 diesel that has high load rating tires and 500 lb hitch weight wouldn’t have any affect on them. How much weight do you currently have on your rear tires? What weight are they rated for at 51 psi. As we’ve mentioned, single axle trailers can be a handful at times. I use different air pressures in mine depending on if I’m towing my 5th wheel, car trailer, or utility trailer. There’s a balance of having max psi for load/sidewall stiffness and not having too much or not enough air so you get maximum tread contact. That’s why I mentioned trying different pressures to see what works best, but you do need enough to handle the load which may be max. Id run it across a scale to see what your numbers really are.

I'd first ask: Are the current tires the correct size for the vehicle (OEM recommended size) or are they "a part of an owner modification which includes a lift kit, larger size tires and other vehicle changes ?????

The answer to what pressure to run comes from understanding the tire size, vehicle configuration much more than the brand of tire on the wheels.

I have a 2021 177 rd also 500# tongue weight I max my f150 tires out at 35# he pulls perfect with friction sway bar. If you don't have a sway bar get one we didn't have one on our pickup trip last year and ordered one the minute we got home. Nothing super bad just makes a huge difference in the wind or being passed. Just some extra info for you to ponder.
