 Mounting the Tire

1.  Remove dirt and grime from the 

mounting surfaces of the wheel and

WARNING

Make sure the mounting surfaces of 

the wheel, hub and lug nuts are clean 

before changing or replacing tires:

When changing or replacing a tire, 

not removing dirt and grime from the 

mounting surfaces of the wheel, hub 

and hub bolts is dangerous. The lug 

nuts could loosen while driving and 

cause the tire to come off, resulting in 

an accident.

2.  Mount the tire.

3.  Install the lug nuts with the beveled 

edge inward; tighten them by hand.

WARNING

Do not apply oil or grease to lug nuts 

and bolts and do not tighten the 

lug nuts beyond the recommended 

tightening torque:

Applying oil or grease to lug nuts and 

bolts is dangerous. The lug nuts could 

loosen while driving and cause the tire 

to come off, resulting in an accident. 

In addition, lug nuts and bolts could 

be damaged if tightened more than 

necessary.
