How To: Installing 9:00-16 tires on CMP wheels

[Bob Carriere]

The proper slow inflation of the tube is critical to avoiding creases in the tube wall.

We actually took a 900x16 tire off the rim and discovered inside an almost new, circa 1980, GoodYear tube that had a bad crease in the sole area and probably would have cause a blowout eventually. Interesting enough the Good Year tube had the following inscription...... 900x16 tires ....for 5 degree rims......

The crease had now become permanent and the rubber was showing signs of cracking.

On the tube inflation we do the following ... inflate the tube to full round before inserting into the tire carcass then allow to deflate while re-inserting the valve to retain "some" air inside. Having the tube valve removed greatly speeds up this simple operation.

Once the tube is inserted we add some air and manually spin adjust the tube stem with the indentation of the rim..... leftover of the "snoth" greatly facilitates moving the tube.

We then deflate the tube, but not totally, to allow installation of the flap.

then do the final reinflation... in slow stages..... listening for the creaking of the tube/flap/tire bead as everything falls in place.

I fully agree with you and would recommend a full deflation and re-inflation of the tire to minimize the chances of any parts being out of place.

Thanks for your comments/suggestions and will do a PS Edit to the slide section.
