5.11 MatchMaker™ Tire and Wheel Mounting Procedure
Tires Mounted on Rims
GSP9700 Series Road Force Measurement System Operation
MatchMaker™ tire and wheel mounting procedure allows the operator to match four
identical tires on identical rims, to achieve the optimal combination of match
mounting. MatchMaker™ provides the operator with on-screen prompts throughout
the procedure.
Mount the tire/wheel assembly on the GSP9700.
Check the tire pressure. Inflation Station will automatically inflate or deflate the tire to
the preset air pressure. When the tire pressure is correct, the tire graphic on the
screen will turn green. Refer to "Inflation Station," page 81.
Measure rim runout by using the inner and outer dataset arms. Refer to "Rim Runout
Measurements," page 54.
Attach an identifying tag to the valve stem of the tire/wheel assembly. Using a tire
crayon or other similar marking device, mark the tire with the same number (1-4) that
is on the identifying tag.
NOTE:
The first tire/wheel assembly in a set must be identified as 1,
the second assembly as 2, the third assembly as 3, and the
last assembly as 4.
Rotate the tire/wheel assembly so that the mark on the on-screen tire is at the 12
o'clock position. Mark the sidewall of the tire at the 12 o'clock position.
Rotate the tire/wheel assembly so that the mark on the on-screen rim is at the 12
o'clock position. Mark the rim at the 12 o'clock position.
Press "OK."
Repeat the procedure for the rest of the tire/wheel assemblies.
After repeating this procedure for all four tire/wheel assemblies, the screen will show
which tires should be mounted on which rims to obtain the best results. You may
choose to show tire/wheel matching based on the optimal road force or based on
making less tire swaps.
Mount the tires to the rims (using the identifying tags attached to the valve stems and
the numbers marked on the tires), aligning the marks on the sidewalls of the tires with
the marks that were made on the rims.
Mount the matched tire/wheel assemblies on the GSP9700 and verify that the proper
road force was achieved.
Balance each tire/wheel assembly using the appropriate balancing procedure for the
particular type of rim construction. Refer to "Balancing Procedures," page 35.
NOTE:
MatchMaker™ also supports measuring bare rims (requires
extra dismount steps) as well as performing "Remount
Centering Quality Checks" for increased accuracy.
