Set front at 55 psi rear at 65 psi rides like a new truck.. will fill all tires to recommended 75 psi when towing thanks to all
Outstanding... I'm glad you didn't go with the 44psi recommendation.
Glad you're happy with the ride now, however, unless you're trying to keep the tpms light off, on an empty truck, 55 is the right range in front, 65 is still way more than you need in back. Nothing bad will happen. Likely won't even have increased tire wear unless they're really wide tires that will balloon up a little more.
Not trying to start an argument and know there's a lot of ways to skin a cat, but I'd still encourage you to try less pressure in back when empty. If you look up load/pressure charts I believe you'll see that for your given weight (15-1700lbs per rear tire empty) 65 is a lot.
Or think of it this way, loaded 1/2 ton crew cab running OE 35psi tires. Back half of a HD pickup is not THAT much heavier, supporting the need for only 5-10psi more.
And no need to air up the front anymore than it already is unless your Adding significantly more weight to the front when you're towing.
Wdh putting a lot of weight up front, not likely on a HD, front hitch with heavy stuff?
Otherwise, why air up the don't when you're really only putting weight on the back?
Again qualitying these pressures are for the common srw 275-295 ish size tires on newer HDs. Have some big 35-37" tires, pressure will be correspondingly less for the same weight. Running 235/245 hi profile donut tires, proper psi for the same truck will go up some.
