U-258STPRO Swing Arm Tyre Changer — T03 Automatic Mount/Demount Head, 400kg Patented Leverless Force, 3-Point Assist Arm & 50% Faster Bead Breaking for Cars, SUVs & Vans

Four hundred kilograms of leverless demounting force. As standard. The U-258STPRO Swing Arm Type Tyre Changer takes the proven U-258SPRO platform and adds the T03 Automatic Mount/Demount Head as standard equipment — a patented leverless tool that delivers up to 400kg of demounting power without a single lever touching the rim. The same tilt-back and swing-arm combination. The same 50% faster bead breaking. The same 3-point assist arm. With the most powerful standard-fit leverless demounting head in the swing-arm lineup added on top. For the workshops where the hardest tyres arrive every day, the U-258STPRO is the machine that was built to handle them.

Description

The U-258STPRO is the force-upgraded variant of the U-258SPRO swing-arm platform — a professional tyre changer that retains every speed, versatility, and structural advantage of the U-258SPRO while adding the T03 Automatic Mount/Demount Head as standard equipment. The T03 head's patented leverless design generates up to 400kg of demounting force — without lever-to-rim contact at any point in the process — making the U-258STPRO the right choice for workshops that regularly encounter the most stubborn, stiff-sidewall, and resistance-heavy tyre fitments and need a machine that handles them cleanly, completely, and without rim damage, every single time.

T03 Automatic Mount/Demount Head — 400kg of Patented Leverless Power, Standard

The U-258STPRO's defining upgrade over the U-258SPRO is its standard-fit T03 Automatic Mount/Demount Head — a patented leverless tool assembly that delivers up to 400kg of mechanical demounting force in a fully leverless operation. Where conventional tyre changers rely on metal levers that apply force through direct rim contact — risking scratching, scuffing, and alloy damage on every difficult demount — the T03's patented leverless mechanism generates 400kg of working force through a controlled, rim-safe tool geometry that never requires lever contact with the wheel. The result is the maximum demounting force available in a leverless swing-arm platform: enough to handle the stiffest run-flat RSC tyres, the tightest low-profile performance fitments, and the most resistant OEM tyre-to-rim combinations — completely, cleanly, and without rim damage. And it comes as standard on every U-258STPRO, not as an optional upgrade.

Tilt-Back + Swing-Arm — Structural Stability Meets Working Flexibility

Like the U-258SPRO, the U-258STPRO's unique column-tilt and side-swing architecture combines the rigid structural stability of a tilt-back column design with the reach, angle flexibility, and working versatility of a swing-arm format — handling more tyre types, more wheel geometries, and more challenging fitments than either single-architecture machine type achieves independently. For workshops servicing a diverse vehicle range from compact passenger cars through full-size SUVs, vans, and light commercial vehicles, the combined architecture means one machine handles every wheel that arrives without configuration compromises.

50% Faster Bead Breaking — The Same Speed Advantage

The U-258STPRO retains the U-258SPRO's new quick dual-exhaust cylinder — delivering bead-breaking speed over 50% faster than conventional single-exhaust tyre changers. Every bead-breaking cycle is completed in significantly less time, keeping the change workflow moving at the pace that high-volume tyre operations require — and ensuring that during peak tyre changing seasons, the U-258STPRO's speed advantage translates directly into more change cycles per shift, more revenue per bay, and shorter customer wait times across the busiest days of the year.

3-Point Assist Arm — Rim Protection and Multi-Function Bead Control

The U-258STPRO's independent 3-point assist arm provides simultaneous three-contact-point bead pressing assistance — distributing bead force evenly across three engagement points for faster, cleaner bead seating and more consistent mounting efficiency on every wheel. The arm's multi-function capability extends across wheel positioning, bead lifting, and bead loosening — making it an active working tool throughout the full change cycle, not just during the bead pressing phase. Rim-protective contact geometry ensures the efficiency and force advantages the 3-point system delivers come without the alloy wheel damage risk that less controlled bead engagement creates.

360° Rotatable Combination Pressing Head — Precise Bead Management at Every Angle

The U-258STPRO's 360°-rotating combination pressing head delivers bead pressing and quick wheel clamping and unclamping from any position around the wheel — combined with the dedicated bead pressing roller and bead lifting roller in the standard accessory set to provide complete, all-angle bead management across every tyre profile and rim configuration in the machine's operating range. Full rotation means the optimal tool position is always available, regardless of tyre geometry or wheel size.

Reinforced Frame — Holds Its Geometry Under Peak Stiff-Sidewall Load

The structural demands on a tyre changer's frame are greatest when handling stiff-sidewall, low-profile, and run-flat tyres — the exact fitments the U-258STPRO's T03 head is engineered to conquer. The reinforced frame structure is specifically designed to prevent deformation under these peak-load conditions — maintaining full geometric integrity, precise tool head alignment, and consistent operational performance even when the T03 head is applying its maximum 400kg demounting force against the most resistant tyre and rim combinations in the machine's operating range.

Upgraded Integrated Motor — High Torque, Low Energy, ≤60dB

The U-258STPRO's upgraded integrated motor delivers high torque output for demanding tyre fitments, reduced energy consumption for lower operating costs at commercial cycle volumes, and a noise level of ≤60dB — keeping the workshop environment quiet for technicians and customers regardless of throughput. The optional dual-speed turntable function allows rotation speed to be matched to specific tyre type requirements for additional precision and control on complex or non-standard fitments.
