Is 25 PSI too low for tires?

The low tire-pressure warning light will display when the tire’s air pressure is 25 percent below the automaker’s recommended PSI. A 25 percent reduction in tire pressure is considered severe. So take the low-tire pressure warning as the warning it is!

Is 38 PSI too high?

Higher pressure generally is not dangerous, as long as you stay well below the “maximum inflation pressure.” That number is listed on each sidewall, and is much higher than your “recommended tire pressure” of 33 psi, Gary. So, in your case, I’d recommend that you put 35 or 36 psi in the tires and just leave it there.

What should tyre pressure be for moderate underinflated tyre?

Moderate underinflated tyre is a tyre in the range 20-49 kPa (0.2-0.49 Bar or 2.90-7.11 psi) under the recommended pressure. These “definitions” are based on Federal Motor Vehicle Safety Standard 138 (THE ROLE OF TYRE PRESSURE IN VEHICLE SAFETY,INJURY and ENVIRONMENT). Tyre manufacturer’s recommended tyre pressure

What happens when tire pressure goes up or down?

As tire pressure goes up or down, so does the load capacity of the tire. Too much air can wear the tires unevenly in the center and can create a wondering effect on the vehicle’s handling. Too little air can wear the tires unevenly on the outer edges and will reduce the tires load capacity below the engineered level.

How is the pressure of a tire rated?

Each tire is rated with a load range, load index number, and max pressure rating. Passenger tires will be rated Light Load (LL), Standard Load (SL), or Extra Load (XL). Extra Load tires of the same size will typically have the same load capacity at the same pressure as the Standard Load tire.

What happens if you have too little or too much pressure on your tyres?

If too much air escapes from your tyres and they are under-inflated, you can experience a range of problems. Too little pressure can result in tyres having uneven contact with the road, increasing wear around the edges. It can also lead to greater flexing, causing damage to the tyre wall structure.
