Did you find that 95 PSI on the tire sidewall or in someones PDF file?

Load ranged tires maximum inflation pressures are determined by the TRA who also approve all manufacturer charts/tables. 95 PSI is standard for LRF tires and 110 PSI for LRG ST tires, that includes the GY G614 RST.

The load index (129) for the LRG ST tire is 4079#, very close to the load range letter "G", 4080#.

NOTE: If you found that 95 psi on the ST LRG tire sidewall it's a very serious safety violation and should be reported to the provider, manufacturer and NHTSA for recall consideration. It could cause the tire to be seriously under inflated when carrying a load greater than the 95 psi would support.

Additionally, Discount Tire, the provider of the Heartland tire have 110 PSI in their PDF file.

There are a number of very good references to read when "plus sizing" your RV trailer tires. Toyo and Firestone/Bridgestone have the easiest ones to work with. Just follow the path to your situation.

It's interesting to note that every one of them note that the plus sized tires should first be recommended by the vehicle manufacturer.
