Frequently Asked Questions
I want to fit lower profile tyres to my car because I’m changing my alloy wheels from 15in to 17in - how can I find the right size?
When fitting a different sized tyre, you need the overall diameter to remain the same. You can try this yourself or visit our shop or simply get-in-touch and will glad to help you. However, always check that a wider than standard tyre will fit inside your wheel arches - the only sure way to do this is to get a tyre fitted to a wheel and try them back and front to ensure they don’t catch on the wheel arches, inner wings, or suspension components.
When should I have my tyres changed on my car?
When the wear indicator appears on the tread, the tyre needs replacing. The minimum legal depth is 1.6mm across the central ¾ of the tread.
We recommend changing your tyres when they reach 2mm.
What kind of tyre is suitable for my vehicle?
You should always accept the manufacturer’s recommendation to obtain the best combination of performance, safety and handling characteristics. Whilst it is sometimes possible to fit a tyre with a higher performance index (speed, load) it is recommended not to fit different types of tyre, for example directional and asymmetrical, on the same axle. There are also many different profiles available with different tread patterns for different applications.
Why, when and how should I check my tyre pressure?
Correct tyre pressure is a key factor in ensuring safety, long tyre life and healthy fuel consumption. Ideally the pressures should be checked when your tyres are cold. Please refer to the manufacturers recommended tyre pressures for your vehicle.
How important is wheel alignment?
Think of it this way. Research indicates that the average car is driven about 12,000 miles per year. A car with toe alignment just 0.34 degrees (Just 0.17 inches) out of specification can drag its tyres sideways for more than 68 miles by the end of the year!
What are the “symptoms” of a car that's out of alignment?
Have your car checked if you notice:
- Excessive or uneven tire wear.
- Steering wheel pulls to the left or right.
- Feeling of looseness or wandering.
- Steering wheel vibration or shimmy.
- Steering wheel is not centred when car is moving straight ahead.
How often should I have my car aligned?
Follow the vehicle manufacturer's recommendation noted in your owner's manual. But, as a general rule, have your vehicle's tires checked every 10,000 miles or at least once a year.
My steering wheel vibrates when I reach a certain speed, why?
The steering wheel vibrates due to an imbalance between the wheel and the tyre. Call into your local Autofit service centre and one of our technicians will check your vehicle. Contrary to popular belief, the rear wheels also need balancing to ensure comfort, optimum tyre life and fuel efficiency.
What should I do when my tyre receives an impact?
You must check the condition of your tyre as quickly as possible. Your Autofit service centre will be happy to arrange this for you. Wheel alignment should also be checked as this may have been affected by the impact.
My car veers when I let go of the steering wheel. Why?
This can be caused by several problems: road camber, tyre pressure, tyre assembly, condition of the tyre or wheel alignment. Your Autofit service centre will be happy to help you identify any problems.
How can I tell if my car has faulty brakes?
Veering
If your car veers to one side when braking then there could be an imbalance in the braking system and you should have your brakes checked at your Autofit service centre as soon as possible. You should also check that your tyres are inflated to the correct pressure.
Excessive pedal movement
If the movement of the pedal is excessive this could indicate a loss of brake fluid, or a mechanical defect such as loose or worn bearings.
Spongy brake pedal
If the brake pedal is spongy to the touch, this could indicate the presence of air or water in the braking system. It could also indicate a mechanical defect.
Brakes feel jerky
If braking is jerky and the steering wheel starts to vibrate when braking, this may be due to wear on the brake discs.
Grinding or squealing noise
A grinding or squealing noise could indicate any of the following problems with your car’s braking system: worn brake pads, rust on the brake disc, missing or incorrectly fitted anti squeal shims.
