 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 is a sway bar - also called an anti roll bar

https://en.wikipedia.org/wiki/Anti-roll_bar

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.

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.

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

Thanks for your input, truly enlightening !!

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

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.

Welcome. Also, why not post a pic of the tyre pressure sticker that is by the door jam. Once other posters have seen what the manufacturer recommended pressures are, they can better advise a good operating pressure for you.

Those tyre pressures aint far off - esp when carrying a load.  Don't, like many, expect a pick up truck to handle like its on rails - it won't.  A pick up is designed to carry goods and as such has fairly rigid/basic  suspension esp the rear and in standard form, run on very high profile tyres.  Pick ups are also relatively high compared to a car.  Remember your driving what is in essence, a goods vehicle and you'll be fine.

 

Depending on where you live though, a pick up is a good choice for Thai roads - they ride the potholes much better ????

Guessing the pictures have to do with shocks..... bad shocks will

 make handling difficult.

 

Had a 49 Chevy once paid $300 in 1975 great truck ran and ran and ran 6 cylinder 

My father did not give me much advice. But one thing he told me was buy the best tires possible for your vehicle. They are the foundation of your vehicle and in reality could prevent an accident or even safe your life.

Vigo's have many sizes of tyres, my 4x4 had 29 PSI all round loaded or unloaded...Other small tyre Vigo's had waaaaay higher pressures.....The door jam tells all for your ride..

Door jam? Did you close it on your foot accidentally?

Yes it is. A slow day on TV.

Folk who go in for a top up are probably not getting the correct pressure anyhooo because the tyre and inside air is hot and PSI will have increased and the advised PSI is for cold tyres..

 

My Vigo PSI was 29/30, if I called in on route 35 would be OK but check them myself the next morning cold, if I had a new tyre or puncture repair I would insist on 29/30..

Here is the Vigo advised cold tyre PSI page from their handbook, yes it can be confusing but just shows the huge difference between different models and tyre sizes regarding PSI..

 

 

 

Apologies if this slightly strays from the topic but given that knowledgeable guys are on this thread I wanted to ask about ‘chipping ' my Isuzu pickup as it’s 4 years old and out of warranty. 2015      3 litre manual 4 door. I understand the process can deliver better economy and power . If anyone can guide me ,or indeed has kit that they now want to sell , I’m all ears.

I did learn from this thread about the different suspension between 2 and 4 door ,subsequently checking my 4 door to notice there are just 2 leafs in the spring and Bridgestone tyres - so thanks for that! 

From my perspective I can say the ride is reasonable other than on patchy surfaces but guess a live axle and leaf springs will always be inferior to a car's setup.

I see.  You usually drive along on your tyres, but sometimes you take it for a scrape on the roof.

Car manufacturers are in constant competition to make cars that deliver better economy and power to increase sales. If by simply “chipping” the ecu this can be achieved, I wonder why their engineers whom are no less brainier, don’t do this already in the first instant.
There must obviously be some long term adverse effects.

There are several car shops across Thailand that can do this. The two best ones I think are:

ECU Shop - https://www.ecu-shop.com/

Powerlab - https://www.facebook.com/powerlabthailand/

I started off getting 2 piggyback ECUs installed that fit in my glovebox. One controls fuel pressure and boost control, the other is a diesel management system.

It took a few hours to install, then one of the mechanics got me to drive the car while he adjusted the tune to suit my driving style. What we found was it was making too much power and the clutch was starting to slip. So he detuned it a bit until I went back a few months later and fitted an upgraded clutch.

The boost controller has 3 power settings, the dms computer has 2. Even on the lowest settings it's like a completely different car to drive. Overtaking is much easier and faster. Throttle response is much better.

I got mine done at Powerlab, but ECU Shop would be just as good I think. The customer service I've had at Powerlab has been great, they really go out of their way to make sure you're happy.
