The two, IMO, are similar to water and oil.... They'll combine and work together to pour over a salad, but not so good behind a tow vehicle....
YMMV

I am starting to lean to 1. on our old 5ver I ran the tires at the max PSI. The original tires (TowMax) were load range E and I ran em at Max PSI 80 and had blowouts, Got Hercules 901s ran em at Max PSI 105 and had blowouts. Got Saliun S637s (Max PSI 110) talked to their tech people about PSI, they asked for weight on axles when I told em they recommended 80psi I ran 90psi put about 20000 miles on em never had the first issue, tires still looked like new when we traded it in.
