Common Alloy Wheel Questions
PCD (Pitch Circle Diameter) is the measurement, in millimetres, of the diameter of the circle on which the wheel studs or bolts are located. For example, a PCD of 5×112 means there are 5 studs/bolts and the circle they form has a 112mm diameter.
Your car’s handbook or online resources specific to your car model should list the PCD. You can also physically measure it (centre-to-centre distance of two diagonally opposite studs/bolts for even numbers, or a more complex calculation for odd numbers).
However when purchasing from Crumpsall Alloys, we ensure the wheels are the correct PCD for your vehicle, so you dont have too!
No. The PCD must match your car’s hub. Using adapters is generally not recommended and can be dangerous.
The centre bore is the diameter of the hole in the centre of the wheel. It’s designed to locate the wheel precisely on the hub.
Spigot rings are used when a wheel’s centre bore is larger than the car’s hub. They fill the gap and ensure a snug fit, preventing vibrations.
If the wheel’s centre bore is larger than your car’s hub, yes, you’ll need spigot rings. This is something we supply free of charge with alloy wheel purchases.
Offset (ET) is the distance, in millimetres, between the wheel’s centre line and the hub mounting face. A positive offset means the wheel sits further inboard, while a negative offset means it sits further outboard. Remember, the lower the number the further out the wheel sits.
Offset affects wheel clearance and handling. A wider offset improves vehicle handling, as it provides a wider track for the vehicle.
Wheel width is measured in inches and refers to the width of the wheel’s rim. Wheel diameter is also measured in inches and refers to the diameter of the wheel rim. These should be compatible with your car’s specifications and the tyres you intend to use. Going too wide or too large can cause clearance issues. We will ensure that the wheel widths are within the correct parameters for your vehicle.
Remember: an alloy wheel which is 8 inches wide would measure 9 inches wide from edge to edge, this is because the width is calculated from the inner barrel.
Alloy wheels are typically made from a mixture of aluminium and other metals, primarily magnesium. Small amounts of other elements like silicon, iron, zinc, and manganese may also be added to enhance specific properties.
No. The specific alloy composition can vary depending on the manufacturer, intended use, and desired properties of the wheel. Different alloys offer different balances of strength, weight, and cost.
Different alloying elements contribute specific benefits:
- Magnesium: Reduces weight.
- Silicon: Improves castability and strength.
- Iron: Increases strength and hardness.
- Zinc: Improves strength and toughness.
- Manganese: Improves strength and workability.
Cast Wheels (Including low pressure cast)
- How they’re made: Molten aluminum is poured into a mold and allowed to cool.
- Strength: Generally the weakest of the three. More prone to bending or cracking.
- Weight: Heaviest of the three. Can impact vehicle performance.
- Cost: Most affordable option.
- Best for: Everyday driving, budget-conscious buyers.
Flow-Formed Wheels (Hybrid forged)
- How they’re made: Start with a cast wheel, then spin it while applying heat and pressure to stretch and compress the aluminum.
- Strength: Stronger than cast, but not as strong as forged.
- Weight: Lighter than cast, offering a good balance.
- Cost: Mid-range price point.
Best for: Those seeking a performance upgrade without the high cost of forged wheels.
Forged Wheels
- How they’re made: A solid block of aluminum is hammered into shape under intense pressure
- Strength: The strongest of the three. Highly resistant to bending or cracking
- Weight: The lightest option. Significantly improves performance and handling
- Cost: Most expensive
- Best for: High-performance vehicles, racing, those who prioritize strength and weight savings.
Ultimately, the best choice depends on your needs and budget. If you prioritize performance and have the budget, forged wheels are the way to go. If you’re looking for a balance of performance and affordability, flow-formed wheels are a great option. And if you’re on a budget and primarily use your vehicle for everyday driving, cast wheels will suffice.
Purchasing wheels on Ebay or Facebook market place can result in a disaster purchase, we have seen this many times, Whether you purchase wheels from ourselves or another company, we ALWAYS recommend purchasing through a retail store.
Incorrect fitment can lead to various problems, including:
- Rubbing: The wheel or tyre may rub against the wheel arch, suspension components, or brake calipers.
- Poor Handling: Incorrect offset can negatively impact handling and stability.
- Damage: In severe cases, incorrect fitment can damage the wheels, tyres, suspension, or even the car itself. We have seen instances where wheels have worked their way loose due to incorrect fitment.
- Legal Issues: Wheels that protrude beyond the wheel arches may be illegal in some jurisdictions.
It’s best to have your wheels fitted by a professional tyre or wheel specialist. They have the expertise and equipment to ensure correct fitment and balance.
We offer home fitting and fitting in store, we also have a number of recommended garages throughout the UK who will fit your wheels with absolute professionalism.

Common Tyre Questions
- Q: How do I know what size tyres I need?
- A: Your vehicle’s tyre size is listed in your owner’s manual, on a sticker inside the driver’s side door jamb, and sometimes on the fuel filler flap. It’s crucial to use the correct size for your vehicle’s safety and performance.
- Q: What do the numbers and letters on my tyre sidewall mean (e.g., 205/55 R16 91V)?
- A: This code provides key tyre information:
- 205: Tyre width in millimeters.
- 55: Aspect ratio (the ratio of sidewall height to tyre width).
- R: Radial construction.
- 16: Rim diameter in inches.
- 91: Load index (indicates the maximum weight the tyre can carry).
- A: This code provides key tyre information:
V: Speed rating (indicates the maximum speed the tyre is rated for).
- Tyre pressure is the amount of air inside your tyres. Correct tyre pressure is crucial for safety, handling, fuel efficiency, and tyre life. Underinflation can lead to overheating and blowouts, while over inflation can reduce grip and ride comfort.
Ideally, check your tyre pressure monthly, including the spare tyre. Also, check before long journeys or when carrying heavy loads.
Your vehicle’s recommended tyre pressure is typically found in the owner’s manual, on a sticker inside the driver’s side door jamb, or sometimes on the fuel cap.
Use a reliable tyre pressure gauge. Check when the tyres are cold (not driven for at least three hours or driven less than a mile) Always go to a reputable garage to check tyre pressures, as Air pumps at petrol stations are rarely maintained and can give false readings.
Tread depth refers to the depth of the grooves in your tyre’s tread. Adequate tread depth is essential for grip, especially in wet conditions. Insufficient tread depth significantly increases the risk of aquaplaning (loss of control on wet roads).
The legal minimum tread depth varies by region. In the UK, it’s 1.6mm across the central three-quarters of the tyre. However, it’s recommended to replace tyres well before reaching this limit.
You can use a tread depth gauge or the “20p test” (in the UK). Insert a 20p coin into the main grooves of the tyre. If you can see the outer band of the coin, your tread depth may be below the legal limit.

There are various types of tyres, including summer tyres, winter tyres, all-season tyres, and run-flat tyres, each designed for specific conditions.
Summer Tyres
Summer tyres are the most common type of tyre, offering adequate grip throughout most of the year.
Winter Tyres (Snow Tyres)
Winter tyres are designed for optimal performance in cold temperatures (below 7°C) and snowy or icy conditions. They offer better grip and shorter braking distances compared to summer tyres in winter
All-Season Tyres
All-season tyres are designed to provide a compromise between summer and winter tyre performance. They offer decent performance in a range of conditions but are not as specialized as dedicated summer or winter tyres.
Run-Flat Tyres
Run-flat tyres allow you to continue driving for a limited distance and speed after a puncture, allowing you to reach a safe place for repair or replacement.
Remember: Run-Flat tyres have many drawbacks, they can decrease ride comfort and increase the risk of cracked or buckled wheels, this is due to the steel belted sidewall which provides no impact damage protection. We do not recommend Run-Flat tyres, even for vehicles which come with them from the factory!
Tyre balancing ensures that the weight is evenly distributed around the wheel and tyre assembly. Imbalanced wheels can cause vibrations and uneven tyre wear. We offer free balancing for wheel and tyre packages.
Tyre alignment refers to the angles at which the wheels are positioned relative to each other and the vehicle. Proper alignment is crucial for handling, tyre wear, and fuel efficiency.
We offer this service in house.
Common tyre problems include punctures, cuts, bulges, uneven wear, and sidewall damage.
What should I do if I get a puncture?
If you get a puncture, safely pull over to the side of the road. If you have a spare tyre, you can replace the punctured tyre. Otherwise, you’ll need to call for roadside assistance or have the tyre repaired by a professional if it’s repairable.
What is a tyre sidewall bulge?
A sidewall bulge indicates damage to the tyre’s internal structure and is a serious safety hazard. Do not drive on a tyre with a sidewall bulge. Have it replaced immediately.
We offer free tyre health checks in store!
