TECHNICAL INFORMATIONS

I. Mounting instructions

Wheels from RONAL are products of high quality.
It is important to observe the following steps for correct fit and for maintenance:

1. Delivery

• Please check whether the wheels were damaged on transport in consequence of
  incorrect handling.

• Transport damages have to be announced to the carriers without delay.

• Please check whether the shipment is complete and in full accordance with your order.
  

2. Application

• Please refer to the attached registration papers to make sure the wheels and tire
  dimensions are admissible for your car (concerns: countries with specific registration
  prescriptions for wheels as accessories; i.e. Germany – TÜV/ABE).
  Attention!
  In view of steady innovation of vehicles, it is indispensable to mount the
  wheels first without the tires to make sure enough space is available to
  brake caliper, springs, stabilisator etc.
  

3. Mounting of Tires

• Before mounting used wheels those should be carefully cleaned and checked
  for damages and ware. Never lay wheels down on the styling side (it might be damaged).

• To mount the tires please use an assembly appliance with rotating head that
  does not touch the wheel (no manual mounting). Please make sure that the
  base of the wheel is not damaged by the breaker. Beads should be treated
  with mounting paste. By means of safety, please make sure that your tires
  always have the correct pressure (please refer to the recommendation of the
  manufacturer).
  Attention!
  Wheels having a negative base rim have to be mounted from the rear side
  only (please refer to wheel indications in TÜV registration papers).
  

4. Balancing

• The balancing works of wheels should be executed on the balancing machine
  over the centre hole (centre lock flange).
  Herefore please adjust tire width, diameter, and position. Electronic
  balancing of the wheels while being mounted on the car only in addition to
  the above stationary balancing; not necessarily being required, however, in
  most cases.
  To avoid corrosion, stick-on weights should be used, if possible. When
  balancing the wheel inside (with stick-on weights behind the spokes) please
  make sure that there is sufficient clearance to any part of the brake
  system.
  

5. Mounting of the wheels

• The surface of the hub must be clean and free of burrs.

• Please use only the mounting parts provided with each wheel.
  For further details regarding the utilization of serial fittings, please refer to the
  registration papers (TÜV/ABE).
  Do not damage the bolt holes when mounting the wheel.

• Please consider the torque as recommended by the manufacturer when fitting
  the wheel.

• After 100 – 200 km the bolts/nuts have to be newly tightened.
  

II. Maintenance

• Regular cleaning (in case of polished wheels in 3 components every week)
  helps to keep the wheels clean and to take pleasure in them in the future.

• For the wheels you may use the same cleaner as for the body of the car. We
  would not recommend special wheel cleaners as they partly contain acid
  substances. By no means should you wash the wheels per steam jet, as the
  transparent coating might be damaged.

• Metal cleaners, scouring pads or other materials that might scratch the
  surface shouldn't either be used.
