1987 MAZDA 626 Workshop Manual

1 2 WHEELS AND TIRES
Regarding tire replacement:
Note the following points when tires are to be removed from or mounted onto the wheels.
1. Be careful not to scratch the tire bead, the rim bead, or the edge of the rim.
2. Apply a soapy solution to the tire bead and the edge of the rim.
3. Use a wire brush, sandpaper, or cloth to clean and remove all rust, dirt, etc., from the rim edge
and the rim bead. For aluminum wheels, use only a cloth for this purpose; never use a wire brush
or sandpaper.
4. Remove any pebbles, glass, nails, etc., embedded in the tire tread.
5. Be sure the air valve is installed correctly.
6. After mounting a tire onto a wheel, inflate the tire to 250—300 kPa (2.55—3.06 kg/cm2,35.55—42.66
psi). Check to be sure that the bead is seated correctly onto the rim and that there are no air leaks.
Then reduce the pressure to the specified level.
7. If a tire iron is used to change a tire on an aluminum wheei, be sure to use a piece of rubber be-
tween the iron lever and the wheel in order to avoid damage to the wheel. Work should be done
on a rubber mat, not on a hard or rough surface. 76G12X-006
