NOTICE
• It is permissible to add 3 psi to the standard tire pressure specification if colder
temperatures are expected soon.
Tires typically lose 1psi (7kPa) for every 12°F temperature drop. If extreme
temperature variations are expected, recheck your tire pressure as necessary to
keep them properly inflated.
• Tire inflation pressures will vary with changes in elevation. If driving in areas of
higher or lower elevation, be sure to check and adjust for proper tire inflation.
CAUTION
• When replacing tires, use the same size originally supplied with the vehicle.
Using tires of a different size can damage the related parts or not work properly.
• When replacing tires, ALWAYS use the same size, type, construction and tread
pattern supplied with the vehicle for all tires.
