U-658 Wheel Balancer — Refreshed Style, 9 Balancing Modes, OPT Function, Split & Hidden Weight Solution & Automatic Measurement for Cars & SUVs

Reliable results. Every time. The U-658 Wheel Balancer delivers the enclosed-hood design, nine balancing modes, OPT optimization, and automatic measurement capability of the premium U-659 platform in a focused, straightforward, workshop-ready package — without the complexity or cost of advanced automation features the operation doesn't need. Refreshed style. Proven measurement. The dependable balancer for workshops that want consistent, accurate results on every wheel, shift after shift.

Description

The U-658 is a professional wheel balancer built for automotive workshops, tyre centres, and service operations that need a reliable, accurate, versatile balancing system covering the full range of modern wheel types and weight configurations — in a refreshed, contemporary enclosed-hood design that reflects the quality of the work the workshop delivers. CE, EAC, and ISO certified, with nine balancing modes, OPT tyre and rim optimization, split and hidden weight capability, and a comprehensive automatic measurement system, the U-658 provides the complete core balancing toolkit in a clean, efficient, accessible platform that performs consistently and accurately on every wheel that comes through the bay.

9 Balancing Modes — Complete Coverage for Every Wheel and Weight Type The U-658's nine balancing modes cover the full spectrum of modern wheel balancing requirements — from the NORMAL clip-on mode for standard steel and alloy wheels through eight ALU adhesive weight configurations (ALU-S1, ALU-S2, ALU-3, ALU-4, ALU-5, ALU-6, ALU-7, ALU-8) that cover standard alloy inner/outer surface placement, hidden weight positioning, split weight distribution, and the adhesive weight tracking mode particularly suited to high-class premium tyres where stick-on weights are the only acceptable solution. For every wheel type the workshop handles — from everyday passenger car fitments to premium alloy wheels where weight placement method and cosmetic finish both matter — the U-658 has the dedicated mode engineered for that specific wheel and weight configuration.

OPT Function — Optimize the Assembly Before Correcting It The U-658's OPT function addresses the tyre-to-rim rotational relationship that standard balancing cannot optimize — analyzing the combined imbalance of the tyre and rim assembly together and recommending the optimal rotational positioning to minimize total assembly imbalance before weight correction is applied. By reducing the source of assembly imbalance rather than just correcting its effect, the OPT function lowers the correction weight required, improves the quality and longevity of the balance result, and resolves the persistent vibration cases where standard balancing produces a technically correct result that the customer still feels — because the tyre and rim eccentricities are compounding each other in an unfavorable rotational relationship.

Split and Hidden Weight Solution — Professional Cosmetic Results on Premium Alloys The U-658's split and hidden weight capability calculates and presents weight placement solutions for configurations where balance weights must be hidden behind spoke structures or distributed across multiple concealed positions — delivering a cosmetically clean, professionally finished result on premium alloy wheels where visible clip-on or adhesive weights are unacceptable to customers. The adhesive weight tracking mode's particular suitability for high-class premium tyres ensures correct weight methodology and placement approach on the most cosmetically demanding wheel and tyre combinations the workshop handles.

Automatic Measurement — Fast, Accurate Setup Without Manual Input The U-658's automatic measurement system captures all three critical wheel geometry parameters — distance from the machine to the wheel, wheel diameter, and wheel width — automatically during the setup phase, eliminating manual data entry and ensuring all balance correction calculations are based on accurately measured wheel geometry rather than manually entered approximations. The automatic width measuring scale provides additional dimensional accuracy and speed, while adhesive weight tracking measurement supports precise weight placement in the premium tyre ALU modes. Faster setup. More accurate corrections. Less time between wheel mounting and spin start on every job.

Refreshed Style — Enclosed Protective Hood Design The U-658's refreshed, contemporary styling features the same enclosed protective hood design as the U-659 — providing a clean, modern aesthetic that reflects professional workshop standards, protecting the internal components from the dust, debris, and splash exposure of an active workshop environment, and presenting a visually consistent, quality-focused equipment line to customers and visitors in the workshop. The enclosed design is not cosmetic alone — the hood's protective function contributes to the long-term reliability and component longevity that the "Reliable Results" positioning of the U-658 is built on.

CE, EAC & ISO Certified — Professional Grade, Globally Compliant The U-658 carries the same CE, EAC, and ISO certification as the U-659 — confirming compliance with international safety, electromagnetic compatibility, and quality management standards for professional workshop equipment across global markets. For workshop operators, distributors, and importers requiring certified equipment for regulatory compliance or customer assurance, the U-658's triple certification provides the documentation and confidence that professional-grade wheel balancing equipment demands.

±1g Accuracy. 8-Second Cycle. 65kg Maximum Wheel Weight. The U-658's core measurement performance is identical to the U-659: ±1g balancing accuracy for precise, reliable correction weight calculation; an 8-second measuring cycle that keeps the balance workflow moving efficiently at any throughput level; and a 65kg maximum wheel weight capacity that covers the full range of passenger car and SUV wheel assemblies within the machine's operating envelope. The 40–510mm rim width range and 252–610mm rim diameter range provide complete dimensional coverage for every standard wheel type in the passenger car and SUV segment.
