driving my new class c

I will add this tidbit. Your front tires probably do not need 80 psi. On certain cars and SUVs I have created better tracking and calmer steering by running higher pressure in rear tires than fronts. This is an old car-tuning trick. Of course, you have to have enough in the fronts to carry the loads. To figure out the possibilities, you have to weigh your RV and then look up the front tire weight loads in an RV tire inflation table. Then you can run whatever PSI it gives. RV makers just say run them full, but they are not the ones living with the RV on the road.

Maybe someone who has done this can tell us if it helped calm down the steering.
