It's a Drag...
Ditto to all of the above.
I have run 30PSI in 500X5 and 380X150X5 tires in my RV's for 20 years. It's the best compromise for ease of moving around hangars, landing on turf and reduction of shimmy on pavement as you decelerate. Maintaining a wheels landing stance after touchdown as long as you can seems to help reduce shimmy also.
If you have a persistent dragging brake, remove the wheel pant, remove the brake pad bolts and slide the caliper out of it's dual ports. (inspect the pads) Take some 2000 grit sandpaper or mineral spirit enriched cloth (I prefer the sandpaper), roll it up and gently hone the inside of the ports and the caliper pins till they are clean.
Re-install, test brakes.
