What to Check and How to Check

Tire Pressure

Proper air pressure for your tires is printed on the

sidewall. Check pressure while tires are cold. Do not

raise or lower pressure to meet load. Pressure other

than recommended pressure will lead to excessive tire

wear or tire failure. Balancing recommended.

Preferred

balancing method is to center off of stud holes, since

13” through 16.5” wheels are not hub piloted.

Wheels

Check wheels for hole elongation or “out of round”. This

condition can be caused by lug nuts not being tight or

being too tight. Trailer wheels can be damaged by

chuck holes or curb jumping. You may not be aware of

the road shock to the wheels without periodic checks.

Replace any wheel that is bent. Replace any wheel if

you see elongation of the bolt holes.

Wheel Lugs

Wheel lug nuts must be tightened with a torque wrench.

Refer to the chart below for proper torque

1. Start all bolts or nuts by hand to prevent cross

threading.

2. Tighten bolts or nuts following

sequence at right.

3. The tightening of the fasteners

should be done in stages.

Following the recommended

sequence, tighten fasteners

per wheel torque chart below.

4. Wheel nuts/bolts should be torqued before first

road use and a fter each wheel removal. Check and

re-torque after the first 10 miles, 25 miles and

again at 50 miles. Check periodically thereafter.
