Want to know what tyre pressure do i need in my pw 50

Possible the recommended pressure is printed somewhere on the tires themselves but will be the maximum. The recommended tyre pressures are Front 25 psi and Rear 30 psi. The tyre pressure must not exceed 50 psi (psi = pounds per square inch).

I dont think these kind of tyres also give maximum load on sidewall, but if so , the needed pressure can be calculated if you know weight on seperate tyres.
I once got hold of the formula for car tyres and went running with it. But for bicycle kind of tyres someone already determined 15% of free flexible part of sidewall deflection is a good starting point.
For car tyres always both sides on the axle the same pressure.
I dont know what kind of vehicle this is about, but system can be used for it.

Weights can be weighed with a persons weightscale in this case I think.

So see what you can find on sidewall and give it here .
Then I will try to calculate.

depending on the vehicle /weight and expected speed, 26-28 psi. heavy vehicle or travelling at high speed it can go up to 30psi. The recommended tyre pressure will be on the specification plate for wheels and tyres on the door edge or door opening pillar. Some makes of tyres have the tyre pressure moulded into the side wall of the tyre.

Hi Anonymous

Your best answer will be found on the tyre the manufacturer will state what the pressure should be but a general guide for an unloaded car (IE no luggage etc) with normal day to day driving conditions would be
front; 2.1 bar, about 30-31 psi
rear; 1.8 bar, about 26 psi

Hope this helps
Kind regards

The required tyre pressure is established by the amount of load or weight that the tyre is carrying. Over or under inflation can cause excessive tire tread wear. The recommended pressures for your tyres are shown in raised lettering on the sidewall of the tyres.
Depending on what you are towing, you will know how much additional weight is being placed on the cars rear tyres, and you can adjust the pressure accordingly.
Personally, When I am towing, I increase the tire pressures by about 5 psi just to reduce sidewall flexing and create a more stable towing package.
Hope this helps.

Yup nice question. For any vehicle accurate tyre pressure will give you better tyre life, low running cost, etc. Here is a chart for car tyres click here.
For bikes i havent found any chart. basically in india rear tyres having 100/90 18inch maximum tyre pressure is 32psi. front tyre having 2.75P or 80/90 18 inch uses 24 psi pressure. and do check your tyre pressure twice a month.

35 psi is the assigned "maximum load" pressure for standard load tires and 41 psi is the assigned "maximum load" pressure for extra load tires.
