Tire Uses

Installation Instructions

Note :
These installation instructions apply for installation on most standard wheelbarrows.
For installation on other equipment, please see the original equipment manufacturer’s manual.

You will need: Crescent Wrench, New Wheelbarrow Tire, Gloves and Eye Protection

Step One:
Put on your gloves and eye protective-wear.
Use your crescent wrench to unscrew the axle brackets that attach the axle to the wheelbarrow. Remove brackets on both sides (Fig. 1).
Step Two:
Remove the axle from the tire and set the axle aside. Dispose of your old tire. Get your new wheelbarrow tire and place the axle through the center (Fig. 2).
Step Three:
Replace brackets onto each end of the axle and rest the brackets into place on your wheelbarrow. Make sure the tire is tight on your axle and cannot move from side to side.
Step Four:
Reattach your axle brackets to the wheelbarrow. Tighten the brackets with a crescent wrench only after you are sure the tire spins freely on the axle and isn’t moving from side to side.

Helpful Hint:
If the tire moves from side to side on your axle, add spacers or washers along the axle on each side of the tire until the tire no longer moves.

Bearing Replacement

You will need: a hammer, screwdriver, block of wood, replacement bearings, gloves and eye protection.

Step One:
Prop the tire up to allow room for the bearings to be removed from the hub. For example, you may use a bucket.
Step Two:
Place the screwdriver through the bearing hole until it hits the backside of the bearing on the opposite side.
Step Three:
Hit the top of the screwdriver with a hammer until the bearing pops out into the bucket below (Fig. 1).
Step Four:
Turn the tire over and repeat steps 1-3 so that both bearings are removed from the hub
Step Five:
To reinstall bearings, rest the new bearing on the opening in the hub and place the block of wood on top of the bearing to avoid hitting the bearing directly (Fig. 2).
Step Six:
Hammer directly onto the block of wood to get the bearing in the hub (the wood block will give you a more even hit). This will require a few hard pounds (Fig. 2). Repeat on the other side to install both bearings.

Helpful Hints:
If the bearing drops freely into the hub prior to hitting with a hammer, remove the bearings and tap gently along the edge of the hub to create a tighter t for the bearing.
Change the location on the backside of the bearing periodically for easier removal.

Inflation Instructions

Safety Warning:
Inflation over 30PSI may cause serious injury/explosion. Never use air compressor. Inflate with a manual pump only. Max inflation 30 PSI. Never overfill your tire.
You will need: Manual Pump, Gloves and Eye Protection

Step One:
Put on your gloves and eye protective-wear.
Remove any weight from the tire. Do not fill the tire when it’s on the wheelbarrow.
Step Two:
Inspect tire and rim for any possible defects. If you see any, don’t fill the tire.
Step Three:
Remove the cap from the valve stem and connect the tire pump to the valve stem. Make sure you follow the tire pump instructions. Use the manual pump to pump up the tire and keep a good eye on the pressure gauge. Don’t go over the tire’s max. 30 PSI.
Step Four:
Disconnect the tire pump from the tire. Set the tire pump aside and put cap back on the tire. Your tire is ready to go.
