E. Tires and Tubes
1. Tires
Bicycle tires are available in many designs and specifications, ranging from
The size, pressure rating, and on some
!WARNING: Never inflate a tire beyond the maximum pressure marked on the tire’s sidewall.
Exceeding the recommended maximum pressure may blow the tire off the rim, which could cause damage to the bike and injury to the rider and bystanders.
The best and safest way to inflate a bicycle tire to the correct pressure is with a bicycle pump which has a
!WARNING: There is a safety risk in using gas station air hoses or other air compressors. They are not made
for bicycle tires. They move a large volume of air very rapidly, and will raise the pressure in your tire very rapidly, which could cause the tube to explode.
Tire pressure is given either as maximum pressure or as a pressure range. How a tire performs under different terrain or weather conditions depends largely on tire pressure. Inflating the tire to near its maximum recommended pressure gives the lowest rolling resistance; but also produces the harshest ride. High pressures work best on smooth, dry pavement.
Very low pressures, at the bottom of the recommended pressure range, give the best performance on smooth, slick terrain such as
Tire pressure that is too low for your weight and the riding conditions can cause a puncture of the tube by allowing the tire to deform sufficiently to pinch the inner tube between the rim and the riding surface, or damage the wheel rim, making the wheel unsafe.
!CAUTION: Pencil type automotive tire gauges can be inaccurate and should not be relied upon for consistent, accurate pressure readings. Instead, use a high quality dial gauge.
Ask your dealer to recommend the best tire pressure for the kind of riding you will most often do, and have the dealer inflate your tires to that pressure. Then, check inflation as described in Section 1.C so you’ll know how correctly inflated tires should look and feel. Some tires may need to be brought up to pressure every week or two.
