2E – 8ITIRES AND WHEELS
DAEWOO V–121 BL4
TIRE AND WHEEL
MATCH–MOUNTING
The tires and wheels are match–mounted at the assembly
plant. Match–mounting aligns the radially stiffest part of
the tire, or high spot, to the smallest radius, or low spot, of
the wheel.
The high spot of the tire is originally marked by a red paint
mark or an adhesive label on the outboard sidewall.
The low spot of the wheel will be at the location of the valve
stem.
Before dismounting a tire from its wheel, scribe a line on
the tire at the valve stem to assure that it is remounted in
the same position.
Replacement tires that are of original equipment quality
will have their high and low spot marked in the same man-
ner.
TIRE MOUNTING AND DISMOUNTING
Notice : Use a tire–changing machine to mount or dis-
mount the tires. Follow the equipment manufacturer’s in-
structions. Do not use hand tools or tire irons to change
tires. These tools may damage the beads or the wheel rim.
1. Clean the rim bead seats with a wire brush or
coarse steel wool to remove lubricants, old rubber,
and light rust. Before mounting or dismounting a
tire, lubricate the bead area well with an approved
tire lubricant.
CAUTION : To avoid serious injury, do not stand over
the tire when inflating it, because the bead may break
when it snaps over the safety hump. Do not exceed
275 kPa (40 psi) of air pressure in any tire if the beads
are not seated. If 275 kPa (40 psi) of air pressure will
not seat the beads, deflate the tire. Relubricate the
bead and reinflate the tire. Overinflation may cause
the bead to break and cause serious injury.
2. fter mounting the tire, inflate it until the beads are
seated. Never exceed 275 kPa (40 psi) to seat the
beads.
3. Install the valve core and inflate the tire to the prop-
er pressure. Make sure the locating ring outside of
the bead of the tire shows around the rim flanges of
the wheel on both sides. This positioning of the tire
will insure that the bead of the tire is seated.

ing base rests on the stator shaft.
2. Set dial gauge to zero.
3. Measure axial play by pulling and pressing on the
handle.(repeat measurement)
