About OZ Racing Wheels...
Born on the track and raised on the street, OZ Alloy Wheels is the brand where Street Style, Racing and Prestige wheels come together to produce one of the most impressive wheel ranges in existence. OZ Alloys have been setting trends on the road and track for years, and are set to continue trend setting well into the future. Perfect lines, impeccable quality, and good enough for Formula 1 – OZ Wheels have it all!
´HIGH LIGHT TECHNOLOGY´ (HLT) - Look out for the HLT logo on some selected OZ designs. Wheels that feature the High Light Technology have undergone further development to drastically reduce the weight of the wheel. This process uses specialist equipment to remove excess alloy to enhance the characteristics of the wheel and reduce the weight. This process DOES NOT affect the structural strength of the wheel!
How to fit your new Alloys...
Fitment Guide
1. When buying wheels only, before fitting tyres to the wheels always check the wheel on the vehicle first. Make sure the bolt holes lines up, that the wheel spigot locates on the hub and that there is suspension strut and calliper clearance.
2. If spigot rings are supplied with your wheels you must ensure they are fitted. Spigot rings are the plastic or metal rings enclosed with your wheels if needed. They basically fit in to the back of the wheel into the centre bore (the hole in the centre of the wheel) and allow you to correctly mount the wheels to the hub, align the bolt holes correctly, and ensure a perfect fit with no vibration once driven upon for added safety and comfort.
3. Once you have mounted the wheel and tyre, before lowering the vehicle, spin the wheel and tyre VERY slowly by hand to ensure that it is not touching on the body, suspension or brake callipers. This will also make sure that if you have fitted bolts that they are not too long.
4. Ensure that the supplied wheel bolts or nuts are correct in relation to both vehicle and wheel. This can be easily tested by hand prior to fitting.
5. The wheel bolts or nuts must be tightened to the manufacturer's specified torque. The bolts and nuts need to be re-torqued 25-50 miles after being fitted. Tightening of bolts or nuts must be done in the correct sequence and progressively i.e. tightening each nut or bolt a little at a time.
6. Check your tyre pressures regularly to ensure they are even and correct. An incorrect tyre pressure can cause increased petrol consumption, uneven tyre wear and poor handling. The correct tyre pressure for your car can be found in your manufacturer handbook.
Alloy Wheels Explained
P.C.D. (Pitch Circle Diameter) explained...
|
|
This is the diameter of an imaginary circle drawn through the centre of the bolt holes. The P.C.D. of the wheel should match the P.C.D. that your car came with as standard.
P.C.D. is measured in mm. e.g.: 4x100 means the wheel has 4 bolt holes and the diameter of the imaginary circle through the bolt holes is 100mm. These details are shown in the Wheel Specifications section on the main product page. |
The Wheel Offset explained...
|
|
The offset determines how far under the arch or how far towards the outer arch a wheel will sit. Each car has its optimum offset and a range within which the offset can be for the wheel to fit the car properly.
If the offset is too low for the range allowed, the wheel could stick out from the side of the car, if too high from what it should be the wheel may catch on the suspension or bodywork as it will be too far under the car.
This is due to the fact that if you put a wheel on your hub with a higher offset than before, the wheels bolting face will have to move further under the car to meet the hub, in extreme cases causing the wheel to sit too far under.
If you take a wheel and cut it in half and draw a line down the centre of the width of the alloy wheel the offset will be the distance between the back face (mounting face) of the wheel and the centre line that you have just drawn.
The offset is commonly shown as the letters ET followed by a number, e.g.: ET49. The offset is always measured in mm and can normally be found stamped on the back of the wheel or behind the centre cap (if fitted). |
Using spacers to change the offset
If the offset of a wheel is too high for your vehicle, in most cases spacers can be used to reduce the offset, pushing the wheel further out to make it sit correctly in relation to the cars bodywork and arches. Rimstyle.com automatically checks if spacers will be required, and if they are, it will tell you. This allows you to fit wheels to your car that aren’t initially made in a direct fit, widening your choice of wheels and is completely safe and road legal to do. However, if the offset of a wheel is too low compared to the offset your car needs, there is no way of rectifying this as they will already sit too far out from where they should be.
Wheel Width and Diameter explained...
The alloy wheel size is shown as follows: Wheel diameter x Wheel width - e.g.: 15x6.5J
The width is the section between the tyre mounting flanges on the wheel / the diameter is the height of the wheel
Wheel Centre Bore and Spigot Rings explained...
This is the diameter of the centre hole in the back of the wheel. It is crucial that the centre bore of the wheel locates properly on the lip on the hub of the vehicle to get a perfect fit. Most wheels work on a spigot ring locating system because most wheels have a centre bore bigger than the size of the hub lip allowing them to fit a wider range of cars. A spigot ring is fitted into the back of the wheel with an outer diameter the size of the centre bore, and an inner diameter the size of the hub lip to allow the wheel to be correctly located onto the hub and to fit tightly onto the vehicle for safety and comfort.
There are wheels that are hub centric i.e. the wheel is manufactured with a centre bore to fit precisely onto a specific vehicle and in these cases we would not supply spigot rings as they would be unnecessary.
If the wheel does not locate onto the vehicle's hub assembly correctly it will cause a vibration on the steering wheel and can lead to bad wear on the tyres and bearings so if spigot rings are provided you MUST use them.
Why fit Alloy Wheels?
1. A set of alloy wheels will improve the appearance of your vehicle and in doing so will make your vehicle stand out from the crowd.
2. Alloy wheels will reduce the weight of a vehicle fitted with standard steel wheels. The benefit of reduced weight is more precise steering as well as a nominal reduction in fuel consumption.
3. Alloy is an excellent conductor of heat, improving heat dissipation from the brakes, reducing the risk of brake failure under demanding driving conditions.
4. There will be a noticeable improvement in the steering response and road holding, especially when cornering!
