Tire Balance and Alignment

The tires need to be balanced to prevent vibration when driving.  This involves attaching small weights to the 

rim to offset small differences in rim and tire weight.  The tires also need to be aligned properly.  Alignment is the 

orientation of the tires to the road surface and their being parallel.  This helps the tires to wear evenly, and provide 

better traction.  Both tire balance and alignment require specialized equipment that is not provided with this vehicle.

Tire Repair

To properly repair a punctured tire, the hole needs to be properly plugged and patched from the 

inside of the tire.  Tread punctures can be repaired if they are not too large.  Sidewall punctures 

should not be repaired, the tire needs to be replaced if the sidewall is damaged.  Tires should 

be removed from the rim to be inspected before being plugged and patched.  A qualified 

mechanic should remove the tire from the rim, perform the repair, and remount the tire.

Figure H:  Tire and Loading Information placard Location

The Tire and Loading Information Placard displays the cold tire inflation pressure and the load 

limit for this vehicle.  See the Tire Care section starting on the following page for an explanation of 

tire pressure and see the Vehicle Load Limit following that for an explanation of load limit.

Steps for Determining correct Load Limit

1.  Locate the statement “The weight of cargo 

should never exceed 271 kilograms or 600 

pounds” on your vehicle’s placard.

2.  That figure equals the available amount 

of cargo and luggage load capacity.

3.  Determine the combined weight of luggage 

and cargo being loaded on the vehicle. 

That weight may not safely exceed the 

available cargo and luggage load capacity.

4.  If the Trailer’s load exceeds the cargo and luggage 

load capacity, then the Trailer will be unsafe 

resulting in hazardous effects, such as:  Trailer’s 

tires will not be able to maintain traction properly, 

and stopping distance will be increased significantly.
