How to Install the 6in Pneumatic Tires

Gather the assembled kit, four wheels, and two 330M belts

Remove one washer and locknut from the truck

Slide a wheel onto the truck that has a pulley, with the pulley facing inward

Secure the wheel with a washer and locknut

Loosen the two motor mount screws if they aren't already

Get a piece of printer paper, and fold it in half three times (so it is 8 pieces thick)

Move the motor mount back from the wheel so there is a gap, ensure that the wheel is as far back as possible

Place the piece of paper between the motor pulley and rim of the tire

Move the motor towards the tire until the motor pulley is lightly pinching the piece of paper

Tighten the two motor mount bolts half a turn at a time to evenly clamp the motor mount

Remove the piece of paper, and you should have a small gap between the motor pulley and tire hub

Remove the locknut and one washer

Then, remove the wheel and add a belt around the motor pulley

Reinstall the wheel with the belt around both pulleys

If you secured the four motor bolts, you will need to loosen them to allow the motor pulley to be close enough to the wheel pulley

Secure the wheel with a washer and locknut

Pull back on the motor to tension the belt

While holding it in this position, tighten the one exposed motor bolt

Remove the one washer, locknut, wheel, and belt

Tighten the other three motor bolts

Reinstall the wheel and locknut to finish the assembly of this side!

The order of parts on the truck from inside to outside should be:

Washer, wheel, washer, locknut

Repeat steps 2-8 to install a wheel (+ pulley) on the other side of the truck

Then, remove one washer and locknut from the front truck

Place a wheel on the truck with the stem facing outwards

Add the washer and locknut back to the truck and tighten (washer, wheel, washer, locknut)

Repeat the process for the other side of the truck

Now its time to inflate the wheels!

We use this nifty protable air compressor from Amazon

Inflate the tires to 50PSI. You should set the compressor to 55-60PSI because some air will leak out when you remove the connector
