Adhesive weights
OE-Adhesive tape - tested by automotive manufacturers
For usage at car manufacturers the OE-tape has to meet high standards. The backing material thicknesses match optimal to each weight and the tape is temperature resistant from -40°C to approx. +250°C. The weight can be moved immediatly following adhesion and with careful handling. The complete adhesion force will be reached after 72 hours. All single adhesive weights are equipped with OE-tape.

Installation of knock-on weights
-
SELECTION OF THE RIGHT WEIGHT
Prior to installation, select the appropriate weight from the HOFMANN POWER WEIGHT range on the basis of the rim shape. The choice is determined by the rim design. The rim flange thickness varies (steel rim/aluminium rim) and different rolling processes are used. Put the weight beside the rim flange before installation to check the shape.
-
POSITIONING THE WEIGHT
Put the weight to the calculated place. Before knocking the weight on the rim, make sure that the clip is correctly touching the rim flange.
-
APPLYING THE WEIGHT
After positioning of the weight, apply it with an adequate tool (such as mounting pliers or hammer). To install the weights, no more than two forceful knocks should be used. A higher number of knocks can damage the coating of the weights.
-
CHECKING THE PROPER INSTALLATION
After application, make sure that the weight is securely fitted.
Installation of adhesive weights
-
PRE-TREATING THE RIM
Clean the rim thoroughly with a cleaning agent that is compatible with varnish (e.g.IPA 70 %) in order to remove any residual grease, silicone or adhesive.
PLEASE NOTE: A minimum of 15 °C is required in terms of both the room temperature and the rim temperature.
-
PRE-BENDING THE WEIGHTS
Separate the correct gramage (as calculated) from the bar. Mould the shape of the weight to match the rim radius (with protective film).
PLEASE NOTE: You need to bend the weights gradually, otherwise they will break apart at the joins. You should bend the weight to a little more than the rim’s radius.
-
REMOVAL OF THE PROTECTIVE FILM
Remove the protective film.
PLEASE NOTE: Do not touch the glued surface after peeling off the film.
-
STICKING THE WEIGHT ON
Attach the weight to the calculated point on the rim, making sure that the weight is distributed evenly either side and the weight is parallel with the edge of the rim.
PLEASE NOTE: Press down on the weight hard, working from the centre to the left and right. A minimum pressure of 1kg/cm² is required. The angle of the sticking surface should not be higher than 15° to normal.
