Tire Diagnosis
Irregular and/or Premature Wear
Irregular and premature wear has many possible causes. Some
of them are: incorrect inflation pressures lack of tire rotation, driv-
ing habits, improper alignment.
If the following conditions are noted rotation is in order:
Front tire wear is different from rear.
Uneven wear exists across the tread of any tire.
Left front and right front tire wear is unequal.
Left rear and right rear tire wear is unequal.
There is cupping, flat spotting, etc.
A wheel alignment check is in order if the following conditions are
noted:
Left front and right front tire wear is unequal.
Wear is uneven across the tread of any front tire.
Front tire treads have scuffed appearance with “feather”
edges on one side of tread ribs or blocks.
Wear Indicators
The original equipment tires have built-in tread wear indicators to
show when tires need replacement. These indicators will appear
as 12 mm (0.47 inch) wide bands when the tire tread depth
becomes 1.6 mm (0.063 inch). When the indicators appear in 3 or
more grooves at 6 locations, tire replacement is recommended.
Radial Tire Waddle
Waddle is side to side movement at the front and/or rear of the
vehicle. It is caused by the steel belt not being straight within the
tire. It is most noticeable at low speed, 5 to 30 mph. It is possible
to road test a vehicle and tell on which end of the vehicle the
faulty tire is located. If the waddle tire is on the rear, the rear end
of the vehicle will shake from side to side or “waddle”. From the
driver’s seat it feels as though someone is pushing on the side of
the vehicle. If the faulty tire is on the front, the waddle is more
visual. The front sheet metal appears to be moving back and forth
and the driver feels as though he is at the pivot point in the vehi-
cle. Waddle can be quickly diagnosed by using a Tire Problem
Detector (TPD) and following the equipment manufacturer’s rec-
ommendations.
If a TPD is not available, the more time consuming method of sub-
stituting known good tire / wheel assemblies on the problem vehi-
cle can be used as follows:
[A] : Hard cornering, under inflation or lack of tire rotation
[B] : Incorrect wheel alignment, tire construction not uniform or wheel heavy acceleration

1) Ride vehicle to determine whether the front or rear waddles.
2) Install tires and wheels that are known to be good (on similar vehicle) in place of those on wadding end of
vehicle. If wadding end cannot be identified, substitute rear ones.
3) Road test again. If improvement is noted, reinstall originals one at a time till waddle causal tire is found. If no
improvement is noted, install known good tires in place of all four. Then reinstall originals in the same man-
ner as above.

Radial Tire Lead
“Lead” is the deviation of the vehicle from a straight path on a level rod even with no pressure on the steering
wheel.
Lead is usually caused by:
1) Incorrect alignment.
2) Uneven brake adjustment.
3) Tire construction.
The way in which a tire is built can produce lead in a vehicle. An example of this is placement of the belt. Off
center belts on radial tires can cause the tire to develop a side force while rolling straight down the road. If one
side of the tire has a little larger diameter than the other, the tire will tend to roll to one side. This will develop a
side force which can produce vehicle lead.
The procedure in above figure (Lead Diagnosis) should be used to make sure that front alignment is not mis-
taken for tire lead.
1) Part of the lead diagnosis procedure is different from the proper tire rotation pattern currently in the owner
and service manuals. If a medium to high mileage tire is moved to the other side of the vehicle, be sure to
check that ride roughness has not developed.
2) Rear tires will not cause lead.
Vibration Diagnosis
Wheel unbalance causes most of the highway speed vibration problems. If a vibration remains after dynamic
balancing, its possible causes are as follows.
1) Tire runout.
2) Wheel runout.
3) Tire stiffness variation.
Measuring tire and/or wheel free runout will uncover only part of the problem. All three causes, known as loaded
radial runout, must be checked by using a Tire Problem Detector (TPD). If TPD is not available, alternative
method of substituting known good tire and wheel assemblies on the problem vehicle can be used, although it
takes a longer time.
[A] : Tire out of round 1. Smooth road
[B] : Tire stiffness variation 2. Suspension movement (loaded runout)
[C] : Rim bent or out of round

Preliminary Checks Prior To Adjusting Front Wheel Alignment
Steering and vibration complaints are not always the result of improper alignment. An additional item to be
checked is the possibility of tire lead due to worn or improperly manufactured tires. “Lead” is the deviation of the
vehicle from a straight path on a level road without hand pressure on the steering wheel. Section 3 of this man-
ual contains a procedure for determining the presence of a tire lead problem. Before making any adjustment
affecting toe setting, the following checks and inspections should be made to ensure correctness of alignment
readings and alignment adjustments:
1) Check all tires for proper inflation pressures and approximately the same tread wear.
2) Check for loose of king pin bearings. Check tie rod ends; if excessive looseness is noted, it must be cor-
rected before adjusting.
3) Check for run-out of wheels and tires.
4) Check vehicle trim heights; if out of limits and a correction is to be made, it must be made before adjusting
toe.
5) Check for loose of suspension arms.
6) Check for loose or missing stabilizer bar attachments.
7) Consideration must be given to excess loads, such as tool boxes. If this excess load is normally carried in
vehicle, it should remain in vehicle during alignment checks.
8) Consider condition of equipment being used to check alignment and follow manufacturer's instructions.
9) Regardless of equipment used to check alignment, vehicle must be on a level surface both fore and aft and
transversely.
Toe Adjustment
Toe is adjusted by changing tie rod length. Loosen right and left
tie rod end lock nuts first and then rotate tie rod to align toe-in to
specification.
In this adjustment, right and left tie rod should become equal in
length (“A”).
After adjustment, tighten lock nuts to specified torque.
Tightening torque
Tie rod end lock nuts
(a) : 65 N·m (6.5 kg-m, 47.0 lb-ft)

Camber And Caster Check And Adjustment
Should camber or caster be found out of specifications upon
inspection, locate its cause first. If it is in damaged, loose, bent,
dented or worn suspension parts and axle housing, they should
be replaced. If it is in vehicle body, repair it so as to attain specifi-
cations.
Steering Angle Check And Adjustment
When tie rod (2) or tie rod end (3) was replaced, check toe and
then also steering angle with turning radius gauge (1).
If steering angle is not correct, check if right and left tie rods are
equal in length “A”.
Steering angle
Inside : 35° ± 3°
Outside : 32° ± 3°
Side Slip(Reference)
For inspecting front wheel side slip with side slip tester:
If side slip exceeds limit, toe or front wheel alignment may out not
be correct.
Side slip limit
: Less than 3 mm/m (Less than 0.118 in/3 ft) NOTE:
To prevent possible incorrect reading of camber or
caster, vehicle front end must be moved up and down a
few times before inspection.
NOTE:
If tie rod lengths were changed to adjust steering angle,
reinspect toe-in.
