MAINTENANCE AND LUBRICATION 257
CAUTION Never bleed air from your tires in an attempt to gain traction for a vehicle stuck in snow, ice or mud. This practice provides no additional traction and typically results in underinflated tires. Never bleed air from a hot tire since that tire will then be underinflated.
To adjust for pressure fluctuations induced by temperature changes associated with winter weather, it is recommended that tire inflation pressure be checked daily when the tires are cold (i.e., before the vehicle is driven). Always use an accurate tire pressure gauge. Inspection Inspect your tires daily. Look for bulges, cracks, cuts, penetrations and/or oil contamination. If any such damage is found, the tire must be thoroughly inspected by a qualified tire inspector and repaired or discarded immediately, at his discretion. Also, check for uneven wear. If found, a thorough inspection of front end parts and alignment should be made by a qualified mechanic. Refer to the Maintenance and Lubrication Manual (TS494) for more information. Tire Manufacturer’s Data Book Specific and more detailed information can be obtained by referring to the technical data books provided by each tire manufacturer. Subjects of interest are: • High-speed or low-speed operation • Repair, retreading and regrooving • Use of tire chains • Mixing radial and bias tires on the same vehicle • Use of dynamometers • Tire mounting/dismounting
