Lug Nut Torque Requirements

It is extremely important to apply and maintain proper wheel mounting torque. Be sure to use only the fasteners matched to the cone angle of the wheel. Proper procedure for attachment of the wheels is as follows:

1.Start all wheel lug nuts by hand.

2.Torque all lug nuts in sequence. See Figure 37. DO NOT torque the wheel lug nuts all the way down.Tighten each lug nut in 3 separate passes as defined by Figure 37.

Table 10. Tire Torque Requirements

wheel size	First pass	second pass	Third pass
	FT-lBs	FT-lBs	FT-lBs
12"	20-25	35-40	50-65
13"	20-25	35-40	50-65
14"	20-25	50-60	90-120
15"	20-25	50-60	90-120
16"	20-25	50-60	90-120

NOTICE

NEVER use an pneumatic air gun to tighten wheel lug nuts.

3.After first road use, retorque all lug nuts in sequence. Check all wheel lug nuts periodically.
