Wheels And Tires, Matching
Hunter RFT33VAG Road Force Touch™ Wheel Balancer:VAS6230B4 can be inserted as an alternative to matching. Refer to Hunter RFT33VAG Road Force Touch™ Wheel Balancer .
General Information
If radial or lateral run-out from rim or tire meet each other, the untrue running of the wheel and tire is increased.
For technical reasons, 100% true running is not possible.
Drive the tires until they are warm before matching them to the tires already on the vehicle. This eliminates any existing flat spots from standing.
Work procedure for match-mounting
-- Let the air out of the tire.
-- Remove the tire bead from the wheel rim flange.
-- Coat the tire bead all the way around with Tire Mounting Paste.
-- Turn the tire um 180° against the rim.
-- Inflate the tire to approximately 4 bar.
-- Tension the wheel with the tire on the balancing machine.
-- Check the run-out or the radial and lateral run-out, as necessary.
If the radial and lateral run-out value is not exceeded, the wheel can be balanced to 0 grams. Specifications are found on.
If the radial and lateral run-out lies outside the specified values, the tire must be turned again.
-- Let the air out and remove the tire beads from the wheel rim flanges.
-- Rotate the tire 90° (one quarter of a turn) relative to the rim.
-- Inflate the tire to 4 bar again and check the run-out.
If the radial and lateral run-out value is not exceeded, the wheel can be balanced to 0 grams.
If the radial and lateral run-out is still outside the specified values, the wheel must be turned again.
-- Press the tire beads off the rim flanges.
-- Rotate the tire 180° (half a turn) relative to the rim.
If the values for radial or lateral run-out are still outside the specified values, check the rim for radial and lateral run-out.
If the measured values for radial and lateral run-out of the rim are within the specified values, then the tire has excessive radial or lateral run-out. In this case, the tire must be replaced.
Assembly paste from mounting tires is located between tires and rim flanges.
Avoid strong braking or acceleration maneuvers during the first 100 to 200 km. Otherwise the tires can turn on the rim. Then the work would then be undone.
