Frequently Asked Questions

Q: When do I need new tyres?
A: It is important that you are familiar with tyre wear and damage. Tyres support nearly every function of a cars motion, including but not limited to road handling, braking and steering - so it is vital that you are sure your tyres are in top notch condition for the road. All tyres over 6 years old should be checked professionally at a Bob Jane T-Marts. Even relatively new tyres need regular checks for sidewall damage such as cuts or bulges, and treads need checking for nails or tears. Contact your local T-Mart on 13 2625 to have your tyres inspected.

Q: What pressure should my tyres be?
A: For everyday motoring, tyre pressure should never be lower than the manufacturer's recommended pressure. This information is usually mounted on the drivers' door edge or pillar, or in the glove box. Tyre pressure should only be checked when the tyres are cold. If you have to check the tyres when they're hot, add at least 2psi (or 13.8kpa) to maintain optimal levels for safety. A good quality tyre pressure gauge allows you check tyre pressure before driving on the tyres; these are available at all T-Marts.

If you are unsure when checking your tyre pressure, drop in to your local T-Mart. They can inflate your tyres to the correct pressure and teach you how to get it right, every time. Call 13 2625 to be through connected to your nearest store.

Q: Why is my steering wheel shaking?
A: The most common cause of steering wheel shake is your wheel balance, so it's important to have this checked as soon as possible at your nearest T-Mart. Besides causing annoying steering wheel vibrations, seat vibrations and increased fuel consumption, improperly balanced wheels reduce road holding ability and also increase wear of shock absorbers, struts, suspension and chassis components.

Only perfectly balanced wheels will give you the assurance that you can keep control of your vehicle even when things get critical. If you are concerned about your wheel balance, we'll have a look for you. Just call 13 2625 to find your nearest T-Mart.

Q: I have a puncture - what do I do?
A: A puncture in your tyre can lead to rapid tyre deflation, so it's important to have a punctured tyre inspected as soon as possible to make sure you avoid permanent wheel damage. The first thing to do when you have a punctured tyre is to change that tyre for your spare.

It's critically important to organise for the punctured tyre to be repaired as soon as possible. Depending on the area of the tyre where the puncture occurs will determine if the tyre is repairable. Generally tyres with punctures in the tread area are repairable, and the technician at your local T-Mart will be more than happy to assist.

  • Cracking Between Tread can be caused by:
    • Fatigue
    • High Torque
    • Incorrect Air Pressure
    • Overloading
    • Age
  • Lug Base Cracking can be caused by:
    • High Torque
    • Incorrect Application of tyre
    • Heat
    • Overloading
  • Shoulder Wear can be caused by:
    • Bent Axle Beam
    • Underinflated Tyre
    • Overloaded
    • Lowering of vehicle with incorrect springs
    • Rotation of tyre not properly timed
    • Defective Wheel Alignment
  • Sidewall Damage can be caused by:
    • A number of factors. It's very hard to identify, however generally it's the result of impact damage or a faulty tyre. In most cases if it's not clearly impact damage, the tyre will need to be cut open to determine the cause.
  • Tyre Abrasion (wrinkles or discolouration) can be caused by:
    • Underinflation
    • Diagonal Wear can be caused by:
    • Underinflation
    • Defective Suspension or rotating parts
    • Rotation of tyre not properly times
    • Defective Wheel Alignment
  • Centre Wear can be caused by:
    • Overinflation
    • Incorrect tyre fitment for wheel
    • Tyre has been inflated for loaded vehicle on a vehicle with no load.
  • Flat Spot can be caused by:
    • Faulty brake system
    • Rapid starting or sudden braking when driving
    • New brakes (drum brakes only)
    • Wheel weight imbalanced

If you have come across any of these symptoms of tyre wear, our staff are always more than willing to assist you in locating the cause of your problem and rectifying the matter. Simply call 13 2625 to find your local T-Mart.

Q. Do I need a new battery?
A. On average a car battery will last between 3 to 4 years. Once a battery has started to fail it rarely responds to recharging, usually due to the positive plate of the battery self destructing, resulting in no plate left to hold a charge that starts your vehicle.

If you've been having difficulties with your battery we can test your battery free of charge, just call 13 2625 to find your local T-Mart.
