GENERAL DESCRIPTION

WHEELS

Chevrolet, Chevelle, Camaro, Chevy n, and Corvette

are base equipped with welded steel wheels. Five studs

with nuts fasten each wheel to the front hub or rear axle

flange. Disc brake equipped vehicles (except Chevrolet

and Corvette) require special 14 inch diameter wheels

with a revised design for clearance, Chevrolet disc brake

equipped vehicles have 15 in. diameter wheels as do all

Corvettes.

Chevrolet station wagons, Chevelle Super Sport 396,

Corvette and Camaro Super Sport 350 are base equipped

with 6 in. width wheels. All other vehicles have 5 in.

width wheels, except Chevy n 100, 300 and 500 Series

Sedans, which have 4 in. width wheels.

Do not install 6 inch width wheels or snow chains on

Chevrolets equipped with rear fender skirts.

TIRES

The factory installed tires on Chevrolet passenger

cars are selected to provide the best all around tire

performance for all normal operation. They are de-

signed to operate satisfactorily with loads up to and in-

cluding the specified full rated load capacity of the
automobile when inflated as recommended in the Vehicle

Capacity Rating and Recommended Tire Inflation Pres-

sures Table (see Specifications).

Optional Oversize and 8-Ply Rating Tires

{Chevrolet and Chevelle Only)

Oversize or 8-ply rating tires are not necessary on

passenger cars for normal requirements. However, an

extra margin of tire service is available when these

options are used at loads up to and including full rated

load.

Optional oversize 4-ply rating and/or 8-ply rating

tires are available on models as indicated in the Tire

Usage Chart (see Specifications). On some models (ex-

ample—Station Wagon), space limitations do not permit

the use of a larger size tire; hence, the 8-ply rating

tire is an available option.

In either case, these tires are applicable to extended

operation at or near full rated load or for trailer towing

when an extra margin of tire service is desired. How-

ever, use of a larger tire or an 8-ply rating tire should

not be construed as permitting an increase in the full

rated vehicle load (see Specifications).

MAINTENANCE AND ADJUSTMENTS

TIRES

Inflation Pressures

To ensure the proper tire inflation pressure for the

owners particular requirements follow the recommenda-

tions in the Vehicle Capacity Rating and Recommended

Tire Inflation Pressures Table (seeSpecifications). Keep

tires properly inflated, and check inflation pressures

periodically. This will ensure the best tire life and riding

comfort, over the full range of driving conditions.
Inspection

Every few thousand miles and at each lubrication, tires

should be checked for sharp objects or stones in the

tread. H tire is punctured, it should be repaired using

one of several repair kits available through tire manu-

facturers1 outlets.

Wear

Misalignment

This is wear due to excessive toe-in or toe-out. In

CHEVROLET CHASSIS SERVICE MANUAL

WHEELS AND TIRES 10-4

the road and it slips, grinding off the tread on the inside

half of the tire at an excessive rate. This type of tire

shows much the same appearance of tread wear as tire

wear caused by negative camber.

Second, the transfer of weight may also over-load the

outside tires so much that they are laterally distorted

resulting in excessive wear on the outside half of the

tire producing a type of wear like that caused by ex-

cessive positive camber.

Cornering wear can be most easily distinguished from

abnormal camber wear by the rounding of the outside

shoulder or edge of the tire and by the roughening of the

tread surface which denotes abrasion.

Cornering wear often produces a fin or raised portion

along the inside edge of each row in the tread pattern.

In some cases this fin is almost as pronounced as a

toe-in fin, and in others, it tapers into a row of tread

blocks to such an extent that the tire has a definite step

wear appearance.

The only remedy for cornering wear is proper in-

struction of owners.

Fig.
5 - Tire Rotatidh

Rotation

To minimize the possibility of tire noise and to equal-

ize tire wear, it is recommended that tires be inter-

changed every 6000 miles as shown in Figure 5 or more

frequently in the case of extremely heavy wear.

NOTE:
Rotate Corvette tires at 4000 miles or

sooner.

Interchanging tires will effectively prevent undue wear

on any particular tire. II tire interchanging is followed

as recommended above, all tires will have the same

number of miles in each wheel position at the end of the

fourth change. When interchanging tires, inspect for

signs of abnormal wear, bulging, etc., stones, glass, and

nails should be removed before reinstallation.

Noise

Noise caused by the normal action of tire treads on

various road surfaces is often confused with rear axle
gears or other noises in the car.

The determination of whether tires are causing the

noise complained of is relatively simple. The car should

be driven at various speeds and note taken of part

throttle, and sudden acceleration and deceleration. Axle

and exhaust noises show definite variations under these

conditions, while tire noise will remain constant. Tire

noise is, however, most pronounced at speeds of approx-

imately twenty or thirty miles per hour.

The tires may be further checked by driving the ear

over smooth pavement with the tires at normal pressure

and again over the same stretch of pavement when the

tires have been inflated to fifty pounds pressure. Reduce

the tires to normal pressure one at a time to determine

the faulty tire or tires. This high inflation pressure

should immediately be reduced to normal after test. If

the noise for which the test is being made is caused by

tires,.
it will noticeably decrease when the tire pressure

is increased, whereas axle noise should show no change

in volume.

If, on inspection, the tires on the front wheels are

found to be creating most of the noise the alignment of

the front wheels should be checked. Excessive tire noise

usually results from lower than recommended tire pres-

sure, incorrect alignment, uneven tire wear, or defective

(thumper) tire.

Cleaning

A great deal of ordinary road dirt which collects on

white sidewall tires may be sponged off with clear water

or a mild soap solution.

A good brand of whitewall tire cleaner, however, is

a quicker and more effective cleaner for removing dirt

and stains from whitewall tires and in many cases it

will remove stains and discoloration that the simpler

method of soap and water will not remove.

Under no circumstances should gasoline, kerosene or

any cleaning fluid containing a solvent derived from oil

be used to clean whitewall tires. Oil in any form is

detrimental to tire rubber and a cleaner with an oil base

will discolor or injure whitewall tires.

Change (W/Wheels)

To change the road wheels using the jack that comes

with the car, observe the following procedure:

1.
Set hand brake and block front wheels if rear wheel

is being changed.

2.
Remove hub cap or wheel disc and break wheel

mounting nuts loose.

3.
Place the jack as directed tinder, General Informa-

tion,
Section 0 and raise car until wheel clears

ground.

4.
Remove wheel mounting nuts and remove wheel from

hub or drum.

5. To replace road wheel, reverse the above instrue-

. tions. Proper torque on nuts is 55-75 ft. lbs.

torque (70-85 ft. lbs. for Corvette aluminum wheel

nuts).

CAUTION: On models equipped with discs, in-

dex the pilot hole in the disc on the valve stem.

(To insure that the anti-rotation notches in wheel

disc register on lugs in wheel rim.)
