Additionally I am a heavy clyde and in recent months have been using my bike to haul back groceries and I will have 8 x 2 litre bottles of Pepsi Max(approx 16kgs) on a rack basket over the rear wheel and I have a very large backpack that when filled up with the sort of stuff I buy, gets to be anywhere from 22kg to 30kg in weight, so I have been putting a big load on my rear wheel in particular.
Sounds like a pretty extreme use case. 75-80psi is crazy high for a 2" tire, and then you're adding up to ~45 kilo + Clyde ? Rim brakes, or not, that's way outside the design envelope for a 'regular' MTB wheel.
If that's the way you regularly ride, you need to look for something Cargo bike /E-bike rated, or accept that 'regular' rims aren't going to live very long under your conditions.
