I’ve noticed that 1/2 ton trucks have the same recommended tire pressures front and rear while 3/4 ton and up always have a pressure offset front to rear. Why don’t they run a offset on 1/2 ton trucks...
The F150 with a 2607 gvwr payload has a 4550 rawr. These trucks rear axle can weigh in the 2200-2300 lb range. Now add 2607 lbs in the bed (payload) = 4800-4900 lbs for a overload condition.
Best is to weigh your trucks front and rear axles separately. That way you will know if those big gvwr based payloads when placed in the bed isn't overloading a tire/wheel/rear spring pack.
