| Seen a set of wheels in a magazine? Know our model or design number? The “Search Wheels” box (above) allows you to specify exactly which alloy wheels you’re looking for by typing in design or model number directly e.g. “AP1”. Click “GO” to display the result. Making absolutely sure they fit? Getting technical…. Pitch Circle Diameter (PCD) Firstly, you need to know the PCD dictates how the wheel bolt holes line up so it is important that this is correct. A PCD of 4x100 meaning 4 bolt holes drilled through the centre of a 100mm circle. Another common PCD is 5x114.3 meaning 5 bolt holes drilled through the centre of a 114.3mm circle. If this is different on your chosen wheels you won't be able to bolt them on! However, we supply many models blank. This means that for a small extra charge your chosen wheels can be drilled to fit your car. Most European cars with 4 studs have a PCD of 100mm (Vauxhall, Volkswagen, Honda & early BMW), Fords & Peugeots have a PCD of 108mm. Also consider whether your car has metric or imperial hubs. Real Minis & MGs have a PCD of 4" which is pretty close to 100mm but not exact so you couldn't swap one with the other. Check the hole in the centre! Many aftermarket alloys have a plastic ring in the centre to take up the gap. Measure the hole in the centre of your vehicles own wheel and compare it to your chosen alloys.  Offset Offset (or often referred to as ET) is the distance between the centre of the wheel and the edge of the rim. This has to be pretty much the same on your new wheels as your own as it will effect the way your car handles. Positive offset is when the hub mounting surface is toward the front or wheel side of the wheel. Positive offset wheels are generally found on front wheel drive cars and newer rear drive cars. Negative offset is when the hub mounting surface is toward the back or brake side of the wheels centerline. "Deep dish" wheels are typically a negative offset. Another reason to be aware of the offset is if the wheel is offset too far one way or another it may contact the wheel arch or suspension.  Offsets can be corrected by machining the alloy wheel or using an appropriate spacer. Please contact us for more details and pricing. Wheel Size Finally, consider the overall diameter. As a rule, if you can achieve the same rolling diameter your original wheels, everything should be fine. Fitting low profile tyres will allow for an increase in wheel diameter. All our prices include low budget tyres. Obviously, speaking to other owners who have fitted larger wheels will help you decide how much of an increase your car can take. Remember a different rolling diameter will affect the reading on your speedo. Use our tyre calculator to show you what the percentage change in your speedo reading will be. |
