Tractor tires are routinely filled with liquid at relatively low pressure. Water is not compressible so the only softening of ride you get is from the expansion of the tire.
Un-regulated water pressure at our house is 180 psi. I sure did blow up some hoses and values, nozzles, etc. until I found out about the pressure. Of course the house pressure is regulated (hope that regulator doesn't fail). Both of our outside standpipes and hose bibs now have pressure regulators. Even they fail from time to time.
