FAQ - Wheels

How do I determine the best offset for a wheel?

The best way to determine the offset for a wheel is by first measuring the non-valve side of your wheel. To do this, place the wheel flat on the ground with valve side up and measure from the ground to the underside of the disk on the non-valve side. If you provide this measurement to our sales department (or via your dealer) our staff can calculate the exact offset for you.

Offset (for wheels with a fixed disk)

The offset expresses the position of the disk in the rim relative to the centre of the rim.
An offset can be 0, negative or positive:

Positive offset
Relative to the centre of the rim, the disk is closer to the valve side. The disk is between the rim centre and the valve.
Negative offset
Relative to the centre of the rim, the disk is located towards the non-valve side. The disk is between the rim centre and the non-valve side.
Offset 0
The disk has the fitting positioned exactly in the centre of the rim.

Molcon Interwheels is available to help you determine the offset. The first step is measuring the non-valve side of your wheel. This is done by placing the wheel flat on the ground with the valve upwards and measuring from the ground to the bottom of the disk on the non-valve side. If you provide this information to our sales department (or via your dealer) our staff can calculate the exact offset for you.

For an adjustable wheel (with screw-off wheel disk), in calculating the offset, you must take into account the position of the lugs and the mounting position of the disk.

How should an All Position Ring be welded in place?

The short side of the All Position Ring is welded on the exterior, the long side on the interior, with welding seams approximately 10 cm long.

In what colours can you paint wheels?

What is the difference between the Molcon Masterfit and the Molcon Economy Line?

The Masterfit is our flagship product when it comes to flexibility and strength. It is a versatile, adaptable wheel, and one of the most powerful and best looking on the market. The Economy Line is a cheaper, fully fledged alternative for the Masterfit when less hp is required

What is the difference between a Molcon Rondofix1 and a Molcon Rondofix2?

In the Rondofix1 version, a flanged disk is pressed into the wheel and welded on one side. In the Rondofix2 version, the disks are not flanged on the exterior and they are circumferentially welded into the rim on both sides.

W-DW-TW rim

The difference between Well, Double Well and Triple Well Rims lies in the rim shape. As the name suggests, a Well-rim has 1 profiling, a Double Well-rim has 2 and a Triple Well-rim 3. The trend towards triple well rims enables lighter-weight wheels to be produced without compromising the strength.

Triple Well-rims offer various advantages:

Stronger rim thanks to extra profiling
Lighter weight: fuel saving
Fast and safer tyre mounting
Less chance of damaging the tyre during mounting
Higher load capacity
