The Importance of Air Pressure

RECOMMENDED AIR PRESSURE CHART: FOR MTB TIRES

For these tires, the pressure varies according to the weight of the rider and the terrain, but also other parameters such as the tire volume, the bicycle (no suspension vs. short travel vs. long travel suspension) and the use are all important factors in the final choice. These three tables should help with the choice of the proper pressure according to use.

TIRE SIZES 47-559 > 52-559

Example: For a cyclist of 178 lbs riding cross-country use, the air pressure should lie between 36 and 44 psi. 36 psi is the low limit to avoid pinch flats. 44 psi is the high limit, beyond which the casing flex is very limited, and in fact the tread rubber is all that deforms to absorb the irregularities in the terrain; the risks of degradation and fast wear are increased. Note: tubeless tire pressure recommendations would tend to be at the middle or lower pressure of the range given. The tubeless tire pressure recommendation for a 178 lbs rider would be 40 to 36 psi.

TIRE SIZES 54-559 > 56-559

TIRE SIZES 58-559 > 62-559

Note: Attention all these values are given only as recommendations. Depending on the experience of the user, they can be adjusted.
