Specifications for the wheels and tires (pressures, torques, etc) can be found at the same link.
When replacing wheels or tires you must comply with local legislation regarding health and safety and correct fitment.
If the vehicle is fitted with TPMS, only Jaguar approved wheels and tyres should be used. If the wheel and tyre size is changed (for example from R18 to R20) the TPMS module should be updated with the correct pressure information appropriate to the new wheel and tyre set. Update the TPMS module using the Jaguar approved diagnostic system.
As a general guideline, only replace tires in pairs or as a set, and only with tires of equivalent size and specification.
Confirm the symptoms of the customer complaint.
As much information as possible should be gathered from the driver to assist in diagnosing the cause(s).
1 . Before a road test, carry out a basic inspection to make sure the vehicle is safe and legal to drive.
Basic inspection •
Correct tire inflation. Specifications
•
Legal tire tread depth. •
Cuts/Bulges in tire sidewall(s). •
Tire ply separation. •
Embedded objects. •
Wheel rim damage. •
Correct tire fitment (specification, direction of rotation, etc). •
Any obvious distortion of the tire (flat/high spots). •
Worn/Damaged steering or suspension components. Front Suspension
Rear Suspension
Road test If the results of the basic inspection are acceptable, carry out a road test to confirm the symptoms.
To reproduce the symptoms, test the vehicle on similar roads to those on which the fault occurs and at similar speeds (provided it is legal to do so).
If the vibration or noise can be reproduced, note the speed at which it occurs and see if it is possible to drive through the symptom, meaning, is it possible to alter the fault by driving faster or slower than the speed at which it occurs?
If it is possible, it is likely that the fault is caused by an imbalance in the wheel or tire. |
