- tire pressure inflation is generally between 90psi to 110psi depending on the mfg of the tire. the tire should have the name of the mfg on it, also the inflation specs, the tire mfg should have all the information of load ratings etc for that tire as long as you have all the information off of the tire so they can identify it for accurate information.

- if you deflate the tire any less than its rated inflation then you risk stability issues. As far as a solid cushion tire there will be no stability issues pertaining to inflation but the tire mfg should also be able to give you rated capacities on that tire as well as long as you have ALL the information off of the tire to give them.

- if you want center of gravity specs for the lift you will have to contact the lift mfg with the model and serial number of the lift in question, their sales reps can get you the standard factory specs on the lift which includes the specs your looking for.
