What's the correct tyre pressure on bicycle wheel size 700 x 38c?
Answers:
A 700 x 38 tyre is a high pressure tire. This means you should inflate to 65- 95 psi. Pressure and volume when it comes to filling a tyre are not the same. Consider the difference with a car tyre. a bicycle tyre uses a very low volume of air at a high pressure- there isn't much air in them but it is under high pressure, while a car, with pressure of 28 to 32 psi has a much larger amount (volume) of air but is at a much lower pressure. This is why you should never use a petrol station filler hose on a bicycle. too much volume and too little pressure!..
It will say on the tire's sidewall. (But I believe it's around 65 lbs.)
In the days when loads of people cycled to and from work, we pumped up our tyres by that amount needed to resist the pressure from the thumb and forefinger when squeezed tight against the side walls of the tyre.
According to the link below pressure should be 50 - 85 psi
maximum pressure is on tyre wall, You choose pressure to suit your comfort and terrain, Low pressure is important in icy or muddy conditions
ragingmk is correct for the schwalbe tire, but keep in mind that tire pressure runs different for different tires for example, a Hutchinson 700x23c is rated at 125 max psi while the Vredestein 700x23c is 160 max psi and the Continental is rated at 125/95 psi. Each company is different.
I think the best advice is to look at the sidewall of your tire and it should have the tire max psi (pressure) for you particular tire posted there.

This is extremely tire-dependent. Some will be between 40-60psi, others will allow 120+psi. Definitely check your tire.
it all depends on what your gonna be riding on if its rough terrain you want a softer tire (55/65 psi) if your gonna be riding on roads etc you want a harder tire beetween 65/80 psi
4 road rideing it should be very high so when you press on the tyre it should be pretty hard to press down even for 3 cm. but for trails or just off road you might want to let out some air so that you can press down for 1-2 cm so that your bike gets a better grip on the road. and the exact pressure depends more on the tube NOT THE TYRE!!
i would said it between 85psi to 100psi, i using 100psi on my 1.0 tire.
