Tyre shop topped up rear tires to 45 and front to 35

 That will be for the tyre rating as factory fitted whatever they were.

I am running Maxxis Bravo A/T. Do the  job for me. 

If your maxxis have a max PSI rating that covers 51 PSI then you are OK, if they don't then Wai to your god...🤣

Rated  to  54 but I never have a load anywhere near enough to require it.

Manufacturers' recommendations are there for a reason.  It you under-inflate, you will get better traction, but greater wear and lower mpg. A few extra bar of pressure will give your tyres less grip, but you will achieve a better mpg.  It is also well to remember, if you over-inflate, that the air inside the tyre will expand as the tyres get hotter, with running.

In my experience all Thais overinflate their tyres.

I was once told that the reason was they wouldn't need to bother checking the pressure for a longer period which to me has always meant sheer laziness.

That frame arrangement looks like an "anti tramp bar". If you apply substantial torque to the prop shaft one wheel is pushed down while the other is lifted up.  The wheel lifted up looses traction and spins thanks to the diff then drops back down. Rinse and repeat. This is "axle tramp". The "anti tramp bar" prevents that. Is this likely to be your problem?

Yup. Every trip to the bike shop gets my tyres inflated to 40-50 pounds. I don't think they even have a pressure gauge, it's whatever comes out of the compressor. I prefer 30 front 35 rear. In fairness though, tyres do seem to loose pressure much faster here than they did back in the cold and wet. When I was commuting every day I had to top the tyres up every weekend.

It would have to very level ground before you reached a tree

Where I have lunch sometimes is opposite a B Quik and it’s a constant stream of cars waiting to top up their tyre pressure, some pick ups but mainly cars, it’s like a drive thru , most don’t get out of their vehicles !!

They definitely don’t adjust the pressure for different vehicles, it’s whatever the compressor delivers .

Oh Boy...................a real mechanical genius here.

It is a sway bar - also called an anti roll bar

If  fitted to the front  yes. Standard for MacPherson Strut suspension. Interesting result if  it  snaps !  Have  had it happen  on a  Rally  car. But the  description  someone offered  of  anti-tramp  is  better for this  unit.

Is this really a thread about someone putting too much air in your tyres?

Thanks for your input, truly enlightening !!

I think what he is trying to say is that there is a pressure gauge connected to the compressor. Unlike those compressors you see at a petrol station where you would set your pressure and it cuts off automatically once the desired pressure is reached, the tyre pressure is controlled by hand.
Sorry, it’s rather hard to describe but once you see it, you will know what I mean.

Okay, thanks for the clarification.
