miles) total under any circumstances
• load the vehicle beyond maximum vehicle load rating listed on the

Conventional spare tire information
If you have the conventional spare tire that is the same size as your
other road tires, you can use the spare as you would any of the other
tires. The spare tire will be equivalent to your road tires, although it may
not have the same appearance (black-side wall instead of outlined-white
letters).
