• Tire Inflation pressures may increase as much as 6 pounds per square inch (p.s.i.) when tires are hot.
• For continuous high speed operation (over 75 mph) increase tire inflation pressures 4 pounds per square inch over the recommended pressures up to a
maximum of 32 pounds per square inch-cool for 4 ply rating tires or 40 pounds per square inch-cool for 8 ply rating tires. Speeds above 75 mph are not
recommended when the 4 pounds per square inch adjustment would require pressures greater than the maximum stated above.
• Cool tire inflation pressure: after vehicle has been inoperative for 3 hours or more, or driven less than 1 mile. Hot tire inflation pressure: after vehicle has
been driven 10 miles or more at 60-70 miles per hour.
• Vehicles with luggage racks do not have a vehicle load limit greater than specified in the tire inflation pressure table.
• When towing trailers, the allowable passenger and cargo load must be reduced by an amount equal to the trailer tongue load on the trailer hitch.
