I'm sure the tires are of the P metric variety. the truck is a lease vehicle so changing the truck tires will probably not happen.
Not officially "recommending" this, but I haul alot of trailers with 1/2 tons with factory tires on them and when a little extra support is needed, I'll air them up to 50psi on 44psi tires and 60psi on 50psi XL tires and it helps a bunch. Typically it's not sway issues for me, flatbed trailers with too much tongue weight usually.
Had 1 1/2 ton that I was working hard pretty regularly. Boss wouldn't get me a HD truck and the equip dept wouldn't put new tires on it. Ran those little Hankook P something or others at about 65 psi for months. Basically tried to blow one up. Was not successful at blowing it up, but it did haul trailers much better!
