FITTING AMERITYRE PUNCTURE PROOF BIKE TYRES
 
Step 1: Measure the rims inner width to make sure you get the right tyre for your bike.

To measure your rims, remove your old tyre and tube and measure the rims inner width from 'bead lip' to 'bead lip' as shown in the rim cross-section (above). Measurement should be taken in millimeters. It is extremely important that you get the right tyre for the right rim. Use the tables to determine the appropriate tyre/rim combination. The color of the tyre does not effect the rim size.

Please note that it is easy to use a one pence piece to identify your alloy rim (18-20mm) as illustrated in this Pic.
 
Step 2: Mount your tires on the rim.
Once you have the correct tire size, you can begin mounting the tire onto the rim. Amerityre's Flatfree™ closed-cell polyurethane foam bicycle tyres have been designed with groove on each side which locks into the 'bead lip' on edge of the rim as shown in the illustration below.
Start with a small section of the tyre and angle it onto the rim so that one side of the groove fits onto the 'bead lip' on one edge of the rim. Then press the tyre into the interior channel of the rim so that the 'bead lip' of the rim snaps into the groove on each side of the tyre as shown in the figures below.
Work your hands around the rim and tire, pressing the 'bead lip' into the grooves on each side of the tire as you go around the full circumference of the rim and tire. You may need two tire tools to assist in the mounting process, one tool to maintain tire position while mounting and the other tool to lever the tire into place on the rim (bottom left).

CAUTION: TO REDUCE THE CHANCE OF DAMAGE TO THE TYRE OR HARM TO THE INSTALLER DO NOT USE A KNIFE OR SHARP METAL OBJECT TO MOUNT THE TYRE.
Once the tyre has been completely installed on the rim, to ensure proper fit, grip the tyre with both hands leaving a space of approximately 4 to 8 inches, then attempt to unseat the tyre from the 'bead lips' by rotating your hands and wrists forward and backward (bottom right).

CAUTION:


Make sure that the rim size is correct. There are some rims that will have a measurement smaller than 18mm or have a measurement somewhere between the tolerances stated above (example - between 14mm and 18mm or between 20mm and 22mm). DO NOT ATTEMPT TO MOUNT THE TYRE IF THE SIZE IS NOT CORRECT!
