3F-4 WHEELS AND TIRES
INFLATION OF TIRES
The pressure recommended for any model is carefully calculated to give a satisfactory ride, stability, steering, tread
wear, tire life and resistance to bruises.
Tire pressure, with tires cold, (after vehicle has set for three hours or more, or driven less than one mile) should
be checked monthly or before any extended trip. Set to the specifications on the tire placard located on the left door
(right door for right-hand side steering car) lock pillar.
It is normal for tire pressure to increase 28 kPa (4 psi) when the tires become hot during driving. Do not bleed or
reduce tire pressure after driving. Bleeding reduces the "Cold Inflation Pressure".
Higher than recommended pressure can cause:
1. Hard ride
2. Tire bruising or carcass damage
3. Rapid tread wear at center of tire
Unequal pressure on same axle can cause:
1. Uneven braking
2. Steering lead
3. Reduced handling
4. Swerve on acceleration
Valve caps should be on the valves to keep dust and water out.
Lower than recommended pressure can cause:
1. Tire squeal on turns
2. Hard Steering
3. Rapid and uneven wear on the edges of the tread
4. Tire rim bruises and rupture
5. Tire cord breakage
6. High tire temperature
7. Reduced handling
8. High fuel consumption
MATCHED TIRES AND WHEELS
(For vehicle equipped with steel wheels)
Tires and wheels are matchmounted at the assembly plant. This
means that the radially stiffest part of the tire, or "high spot", is
matched to the smallest radius or "low spot" of the wheel.
This is done to provide the smoothest possible ride.
The "high spot" of the tire is originally marked by paint dot on the
outboard sidewall. This paint dot will eventually wash off the tire.
The "low spot" of the wheel is originally marked by paint dot on the
wheel rim-flange. Properly assembled, the wheel rims' paint dot
should be aligned with the tires' paint dot as shown in left figure.
Whenever a tire is dismounted from its wheel, it should be re-
mounted so that the tire and wheel are matched. If the tire's paint
dot cannot be located, a line should be scribed on the tire and
wheel before dismounting to assure that it is remounted in the
same position.
