Touchless tire-grip clamp
Extended tire-grip capacity for larger wheel assemblies.
The QC20 is designed for North American alignment bays that regularly service vehicles with larger rims. It replaces a traditional rim-mounted wheel clamp with a three-point tire-sidewall grip. The clamp attaches to the outside of the tire rather than the rim, helping protect alloy, chrome, painted and refinished wheels.
It is designed for fast, repeatable target positioning in TreadPlus 9000 aligner workflows.
Application note: QC20 is designed for the larger rim sizes commonly encountered in North American workshops. Confirm compatibility with the selected aligner configuration.

How it works.
The clamp seats on the tire sidewall, self-centers with a three-jaw mechanism, carries the alignment target, then releases after measurement without touching the rim face.
PositionPlace the clamp against the tire sidewall.
GripThree-point jaw set centers on the tire.
MeasureMount the target and continue the SureAlign workflow.
ReleaseRemove the clamp without rim contact.
Traditional rim clamp
Rim clamps require direct contact with the wheel rim. That can create customer concern on wheels with delicate finishes or wheel covers.
QC20 tire-grip method
The clamp holds from the tire sidewall and keeps the rim surface untouched, while still allowing the alignment target to be used in the normal workflow.

QC20 frequently asked questions.
Does QC20 use the same tire-grip method as QC15?
Yes. QC20 also uses a three-point tire-sidewall grip intended to avoid direct rim contact during normal use.
What tire range does QC20 cover?
The published QC20 range is 20–42 inches. Confirm vehicle clearance and aligner compatibility before ordering.
When should QC20 be selected instead of QC15?
QC20 should be considered for tire assemblies that exceed the QC15 capacity or where the larger clamp range is required.
Compare clamp options.
QC15 is designed for common passenger-vehicle tire sizes. QC20 extends the range for North American vehicles with larger rims and tire assemblies.
