Speedy Corporation Pty. Limited is privately owned and was founded in 1999. The company imports, warehouses and distributes automotive steel wheels, alloy wheels and wheel accessories.
The company markets these products under the Speedy Wheels brand, within Australia, New Zealand and the Pacific Islands aftermarket industries.
Speedy Corporation Pty. Limited also provides specialised logistical services for the tyre industry, from it’s company owned state of the art warehouse and distribution complex at St Marys, in Sydney.
The origins of the Speedy Wheels brand dates back to May 1957, when the now famous brand was foundered by Mr. Keith Tonkin with the establishment of a family run steel wheel repair and steel wheel widening business, operated from a rusty old disused tin dairy shed, at Brighton in southern Sydney.
Over the ensuing years, Speedy Wheels has gone on to become an iconic brand within the Australian Automotive Aftermarket.
From the most humble of beginnings back in 1957 to the present day, where the brand is sold through a national network of authorised retailers. The Speedy Wheels brand enjoys strong consumer recall, built upon a reputation for quality of manufacture and engineering excellence, innovation in design, technical superiority and a range of value for money products, which are underwritten by the wheel industry’s leading product warranty guarantees.
Fitting a set of wheels with the correct offset is most important. Yet, because there are two commonly used (but different) methods for measuring offset, much confusion reigns.
At Speedy Wheels we understand both the “backspace method” and the “centreline method”, so a short explanation of each may assist you in selecting the correct offset wheels.
Backspace Method: Measure from the extreme rear edge of the rim to the hub mounting face. Distance “A” in millimetres.
Centreline Method: Measure the overall width of rim (Distance “X”), halve this measurement to find centreline then measure backspace (Distance “A”).
Subtract “A” from “X/2” and you now have the centreline offset, which in Australia is written 35P or 10N to denote either positive or negative centreline offset. In Europe, centreline offset is usually written ET35 or ET-10 etc.
NOTE: The centreline offset measurement is “rim width dependant”, ie. as the width of the rim changes, so does the centreline offset, eg. if you have 14 x 6 wheels with 47P offset and would like to fit 14 x 7 alloys with the same backspace, then the same offset in 14 x 7 is 35P. In both instances, the backspace remains at 135mm.
P.C.D. (Pitch Circle Diameter)
The P.C.D. of a wheel refers to the diameter of an imaginary circle drawn through the centre of the nut/stud holes in the mounting face of the wheel.
An example of a P.C.D. is 5×120, where 5 indicates the number of holes (for studs/nuts) and 120, a diameter of 120mm.
Hub Location – Alloy Wheels
The hub hole is the hole in the centre of the wheel which mates with the centre hub of the car.
By not locating a wheel on the cars’ centre bore, the vehicle can sometimes encounter vibration problems.
All Speedy alloy wheels are either supplied with centre bore locating rings or are machined to be a perfect fit with the vehicles hub to completely eliminate any of the above mentioned scenarios.
