WHEELS & TYRES

Matched tyres and wheels :

Tyres and wheels are matchmounted at the assembly

plant. This means that the radially stiffest part of the

tyre or “high spot” marked in RED on tyre is matched

to the smallest radius or “low spot” of the wheel. This

is done to provide the smoothest possible ride. The

'highspot' of the tyre is originally marked by paint dot

on the outboard sidewall. This paint dot will eventually

washoff the tyre. The 'low spot' of the wheel is

originally marked by paint dot on the wheel rim.

Properly assembled, the wheel rims' paint dot should

be aligned with the tyres paint dot as shown in the

figure 2. Whenever a tyre is dismounted from its wheel,

it should be remounted so that the tyre and wheel are

matched. If the tyre's paint dot cannot be located, a

line should be marked on the tyre and wheel before

dismounting to assure that it is remounted in the same

position.

Inflation of Tyres :

The pressure recommended for any model is carefully

calculated to give a satisfactory ride, stability, steering

tread wear, tyre life and resistance to bruises.

Tyre pressure, with tyres cold, (after vehicle set for

three hours or more, or driven less than onmile) should

be checked monthly or before any extended trip. It is

normal for tyre pressure to increase (4 psi) when the

tyres become hot during driving. Do not bleed or

reduce tyre pressure after driving. Bleeding reduces

the “Cold Inflation Pressure”.

Higher than recommended pressure can cause :

Hard ride

Tyre brushing or carcass damage

Rapid tread wear at center of tyre

Unequal pressure on same axle can cause :

Uneven braking

Steering load

Reduced handling

Swerve on acceleration

Valve caps should be on the valves to keep dust and

water out.

Lower than recommended pressure can cause :

Tyre squeal on turns.
