How to Choose a Tyre Baler: Key Specifications and Performance Criteria

Updated on: 5th March 2026 By:

A tyre baler is a significant capital investment, typically in the £25,000 to £70,000 range depending on specification, and the performance difference between a well-specified machine and a poorly matched one is measured in bale quality rejections, maintenance downtime, and throughput shortfalls that compound over years of operation. The decision deserves more rigour than a headline price comparison.

This guide covers the criteria that experienced tyre recyclers use when evaluating tyre balers: throughput capacity, bale quality and PAS 108 compliance, tyre category compatibility, drive system reliability, and the after-sales factors that determine the real cost of ownership. Working through these criteria in order, against your own operation’s requirements, produces a shortlist based on fit rather than marketing.

Throughput Capacity: Matching Output to Your Daily Volume

Throughput is the number of bales a machine can produce per hour under normal operating conditions. A baler rated at 6 bales per hour can produce 48 bales in an 8-hour shift. At 10 to 15 passenger car tyres per bale, that is 480 to 720 tyres processed per shift. Compare this figure to your average daily tyre intake to confirm the machine has sufficient headroom. Running a baler at 90% of its rated capacity continuously is harder on the equipment than running at 70%, and production spikes at collection events can push demand above your average intake.

Throughput figures from manufacturers are measured under consistent conditions with a standard car tyre size. Actual throughput varies with tyre size mix, operator experience, and the physical layout of the processing line. Ask for throughput data that reflects the tyre mix you actually process, not just the headline rate with standard car tyres.

Operation Size	Daily Tyre Volume	Required Throughput	Suitable Model Range
Small recycler / dealer	100-300 tyres/day	2-4 bales/hr	Compact baler; entry-level spec
Mid-size recycler	300-800 tyres/day	4-6 bales/hr	MKII Tyre Baler or equivalent
Large recycler / processor	800-2,000+ tyres/day	6+ bales/hr	MK3 or high-throughput spec
Municipal collection point	Variable; event-based	4-6 bales/hr minimum	MKII; portable system for events

Bale Quality and PAS 108 Compliance

Bale quality is the criterion that most directly affects the revenue side of the tyre recycling business. A bale rejected by a TDF buyer or civil engineering customer because it does not meet their specification is a bale you cannot sell at full value. PAS 108, the British Standard for whole tyre bales in civil engineering, specifies bale dimensions (approximately 1,600 x 1,200 x 700mm), minimum wire ties (6), and density requirements. Buyers in civil engineering, export, and TDF markets increasingly reference PAS 108 as a baseline quality specification.

The Gradeall MKII Tyre Baler produces bales to PAS 108 specification at up to 6 bales per hour. Confirming that a baler produces bales within PAS 108 dimensional tolerance is not a theoretical exercise; ask the manufacturer for bale dimension data from actual production runs, not just from the machine design specification.

Tyre Category Compatibility: Car, Truck, OTR

Not all tyre balers handle the same tyre categories effectively. A machine designed for car and light van tyres will struggle with 22.5-inch truck tyre formats, producing inconsistent bales or causing excessive wear on compression components. Before specifying a baler, define the tyre mix you process or intend to process: predominantly car tyres, a mixed stream including some truck tyres, or a commercial truck focus.

If your operation handles commercial truck tyres, a sidewall cutter upstream of the baler is essential for consistent bale quality. The Gradeall Truck Tyre Sidewall Cutter removes the rigid bead and sidewall sections before the tyre enters the baler, reducing spring-back, improving bale density, and extending the baler’s working life by reducing peak compression loads.

Drive System and Hydraulic Specification

The hydraulic system is the core of any tyre baler, and its specification determines both performance and maintenance cost over the machine’s life. Key parameters are hydraulic pressure (typically 250 to 350 bar for tyre balers), cylinder bore and stroke (larger bore delivers more force at the same pressure; longer stroke handles taller tyre stacks), and the hydraulic pump and motor specification. Undersized hydraulic systems are the most common cause of poor bale density and slow cycle times on cheaper machines.

Ask for the full hydraulic specification: working pressure, cylinder bore, pump flow rate, and motor power. A manufacturer that publishes these figures is confident in the specification. One that provides only headline press force numbers without the underlying hydraulic parameters warrants closer scrutiny.

After-Sales Support and Parts Availability

“The machine that matters is the one still running in year five, not the one that looked good in the brochure,” says Conor Murphy, Director of Gradeall International. “After-sales support, parts availability, and the manufacturer’s track record for standing behind their equipment are factors that a price-only evaluation misses entirely.”

Gradeall has been manufacturing tyre recycling equipment for nearly 40 years from its facility in Dungannon, Northern Ireland. The tyre recycling equipment range is exported to over 100 countries, with OEM spare parts available globally. When evaluating any tyre baler, ask for the typical lead time on wear parts, the cost of a hydraulic seal kit, and whether technical support is available directly from the manufacturer or only through regional agents.

Frequently Asked Questions

What press force is sufficient for a tyre baler?

Press force for car tyre balers typically ranges from 60 to 120 tonnes. Higher press force produces denser bales and handles larger tyre formats more effectively. However, press force alone is not a complete specification; the hydraulic stroke length and cylinder bore determine how that force is applied across the bale stack. A machine with 100 tonnes of press force and a short stroke may produce lower-quality bales than a 80-tonne machine with a longer stroke and optimised compression geometry. Evaluate the bale output specification alongside the press force figure.

How many wire ties does a PAS 108-compliant bale require?

PAS 108 specifies a minimum of 6 wire ties per bale. The wire specification (diameter, tensile strength, and tie configuration) is also defined within the standard. Bale wire supplied by the equipment manufacturer to the correct specification ensures compliance; substituting cheaper wire of lower specification risks bale integrity during transport and storage, which can result in buyer rejection on delivery. Use manufacturer-specified or equivalent wire to maintain compliance.

Can a tyre baler handle split or damaged tyres?

Most tyre balers can accept tyres with cuts, sidewall damage, and minor deformations without significant performance impact. Whole tyres, even damaged ones, compress into bales acceptably. Heavily contaminated tyres (mud-filled, with embedded stones, or carrying hazardous residues) can cause hydraulic system contamination and should be excluded from the baling stream. Check with the manufacturer on the specific contamination limits for the model you are evaluating.

How do I confirm a baler produces PAS 108-compliant bales?

Request a production test with your tyre mix, measure bale dimensions and count wire ties on completed bales, and ask for the manufacturer’s statement of PAS 108 compliance. A reputable manufacturer will provide bale dimension data from actual production and will confirm which bale wire specification is supplied with the machine. If evaluating a baler remotely, ask for photographs or video of bale output with a measurement reference, and confirm the wire tie count in the images.

Is a used tyre baler a viable option for a startup recycler?

Used tyre balers are available in the market and can represent a lower entry cost for startup recyclers. The risks are hydraulic system wear (seals, cylinders, and pump condition are not visible without inspection), wear component condition (pressing plates, wire guides), and the absence of a warranty. If purchasing used, have the hydraulic system inspected by a qualified engineer, confirm parts availability for the specific model, and negotiate a short warranty period from the seller. A used machine from a reputable manufacturer with known service history carries less risk than a low-cost new machine from an unknown origin.
