Polycoat Tyrefill Vs Ballast Vs Solid Tyres: Which And Why
This guide is for plant, waste and construction fleets operating on debris‑strewn sites where punctures, stability and uptime are critical. It compares three approaches: Fieldens Polycoat Tyrefill (foam-filled pneumatic), liquid ballast or counterweights, and solid/resilient tyres.
Use this framework to balance uptime, stability, load capacity, operator comfort, speed/heat limits, ground pressure and whole‑life cost. For sector‑specific advice, see our sectors we serve. We supply and fit industrial tyres and deliver complete UK wheel and tyre packages with engineered, long‑life solutions.
Engineering Basics: Load, Heat, And Ground Pressure
Start with the load index and duty cycle. Axle loads, lift heights and attachments set the baseline. The wheel must safely carry a filled‑tyre or solid‑tyre weight, including dynamic loads and any added ballast. Match ratings to real site conditions and shift lengths.
Tyres generate heat through sidewall deflection. Higher speed, long travel and under‑inflation increase heat. Foam‑filled tyres usually run cooler than solids but hotter than air at speed; solids store heat and have stricter speed and distance limits. Read more on demanding conditions for rim and tyre.
Footprint (contact patch) drives stability, ride and ground pressure. Correct inflation or fill, casing design and tread pattern affect vibration and comfort. Specify the wheel precisely: offset, bead seat, PCD and centre bore. Fieldens OTR Ltd uses ISO 9001 processes to verify fit and duty.
Option 1: Fieldens Polycoat Tyrefill
Polycoat Tyrefill is a two‑part elastomer pumped into a pneumatic tyre. It cures to an elastic core, removing air and preventing punctures. The tyre retains controlled flex for a smoother ride than solids and a stable, predictable footprint.
On loaders, telehandlers and skid steers, Tyrefill delivers near‑100% puncture elimination, improved stability and fewer callouts. Manage added weight and heat: avoid long, fast road runs. Choose radial or bias casings from partners such as Michelin, BKT and ATG to suit the job.
Success depends on sound wheels, correct valve positioning and precision filling. Our technicians fill and balance under ISO 9001 controls. Learn more about Tyrefill by Fieldens OTR Ltd.

Option 2: Liquid Ballast And Counterweights
Liquid ballast (water/glycol) or steel counterweights lower the centre of gravity and can increase traction. On low‑speed, flat sites this may improve stability, especially when handling heavy attachments or loads.
However, ballast does not prevent punctures. It can worsen handling over rough ground due to inertia, and adds stress to tyres and driveline. Ride comfort is often reduced versus air‑only setups.
There are maintenance risks: potential rim corrosion, valve issues and antifreeze handling. For background, see should you put water and antifreeze in tractor tyres. For most industrial and waste sites, we can advise better alternatives.
Option 3: Solid And Resilient Tyres
Solid and resilient tyres include mono solids, two‑ or three‑stage resilient designs, and press‑ons. Compounds resist cuts and chunking in scrap or waste yards and provide absolute puncture‑proofing with very high stability.
Trade‑offs are a firmer ride, higher ground pressure and heat build‑up at speed. Travel distance and speed must be restricted. They are excellent for forklifts and indoor waste yards, but are less suited to mixed on/off‑road work.
Correct wheel fitment and compound choice are essential. Fieldens OTR Ltd specifies wheel dimensions, press‑fit tolerances and compounds to match your floor, load and cycle.
Side-By-Side: Tyrefill Vs Ballast Vs Solid
Key differences at a glance:
- Puncture protection: Solid = complete; Tyrefill = near‑complete; Ballast = none.
- Stability: Solid = very high; Tyrefill = high and predictable; Ballast = variable (depends on fill and distribution).
- Ride comfort: Tyrefill = best balance; Ballast = moderate; Solid = firmest.
- Speed/heat tolerance: Tyrefill = moderate; Solid = low; Ballast (air) = per the pneumatic tyre’s speed rating.
- Ground pressure: Solid = highest; Tyrefill = moderate; Ballast (air) = lowest (inflation‑dependent).
- Whole‑life cost: Weigh downtime and callouts saved (Tyrefill/Solid) against purchase price, fuel/energy from added weight and tyre life.

Decision Framework: Choose By Site, Machine, And Duty
- High puncture risk (nails, rebar, scrap): shortlist Tyrefill or solids.
- Regular road travel or higher speeds: favour Tyrefill; avoid solids.
- Forklift on smooth, predictable yards with heavy counterbalance: solids are strong candidates.
- Low puncture risk but need extra stability/traction: ballast or counterweights may suffice.
Check axle loads, wheel capacity and tyre speed ratings. Confirm inflation data and manage heat on longer travel. Share site photos, machine data and routes for a firm recommendation.

Wheel And Tyre Package: Bespoke Builds That Fit First Time
Filled or solid tyres must match the right wheel: offset, PCD, centre bore, bead seat type and any lock rings. We position valves correctly and account for TPMS (tyre pressure monitoring systems) or inflation equipment. Our team designs to exact specification, then verifies fit and clearance.
We stock and source tread patterns for waste, L5, traction and smooth from Michelin, BKT, ATG and others. We build complete wheel‑and‑tyre packages, pre‑fitted and ready to work.
Explore our manufacturing capability and book delivery and fitting on site or at our workshop. All work follows ISO 9001 quality checks.
Recommended Options By Application
Waste handlers, loaders and telehandlers in MRFs/transfer stations: Polycoat Tyrefill on quality radial or bias industrial casings to balance ride, stability and uptime. Solids suit slow, indoor‑only work where comfort is less critical.
Skid steers and backhoes on demolition: Tyrefill is the default for debris‑heavy conditions. Choose cut‑resistant tread patterns and manage heat on longer transits.
Forklifts and access platforms on smooth yards: Solid or resilient tyres minimise downtime and maximise stability. Use Tyrefill where mixed travel, ramps or operator comfort call for a softer ride.
Maintenance And Inspection For Filled And Solid Tyres
Carry out routine checks:
- External damage, tread wear and remaining life (or wear lines on solids).
- Wheel condition, fasteners and valve hardware; confirm nut torque after heat‑intensive runs.
- Signs of heat build‑up on long travel; adjust duty or speed if required.
- Record issues by position to spot patterns and schedule replacements.
Tyrefill removes puncture repairs, but tyres still wear; replace when tread or casing is consumed. Rotate solid tyres where possible and replace at wear indicators. Dispose or recycle responsibly. For basics that save money, read the cost of poor tyre care.
Foam Fill Pricing Context And Best-Fit Applications
Foam fill pricing is best viewed as a specification-based cost, not a fixed price per tyre. The amount of Polycoat Tyrefill required depends on tyre size, internal volume, casing type and how the machine is used. Larger OTR, plant and industrial tyres naturally require more fill material, so accurate pricing normally starts with the tyre size, machine make and model, working surface and duty cycle.
The key comparison is not just foam fill versus the cost of a standard pneumatic tyre. It is foam fill versus the total cost of punctures, callouts, downtime and lost production. On sites where tyres are regularly exposed to nails, rebar, scrap metal, broken concrete, glass, sharp stone or waste material, a cheaper upfront tyre can quickly become more expensive if the machine is repeatedly stopped.
Typical applications include telehandlers, loading shovels, skid steers, backhoe loaders, access platforms, trailers and low-to-moderate-speed machines working in waste, recycling, demolition, construction, agriculture, plant hire and industrial yards.
Compared with ballast, foam fill adds useful weight and stability while also reducing puncture risk. Compared with solid tyres, it can provide a more forgiving ride and allows the use of pneumatic tread patterns suited to mixed ground conditions.
Cost And ROI: Quick Model You Can Copy
Use a simple model: purchase + fitting + extra fuel/energy from weight versus downtime saved + callout/repair costs avoided + productivity gained. Include tyre life and the cost of missed shifts.
Example: a waste loader suffers two punctures per month. Each callout costs £250 and loses 3 hours of work at £120/hour. That’s £610 per incident and £1,220/month in direct and lost time. Tyrefill removes almost all puncture‑related downtime, often paying back within months.

FAQs
Can Tyrefill Be Removed Or Retreaded?
Tyrefill is semi‑permanent. The tyre can be cut off the wheel if needed. Retreading depends on casing condition and application.
What Speed Can I Run With Tyrefill Or Solids?
Speed depends on tyre size, load and duty. Tyrefill allows moderate speeds; solids are for low speed and short distances. Always follow tyre and machine limits and manage heat.
How Much Extra Weight Will I Add?
Added weight depends on tyre volume and size. Check axle ratings and wheel capacity before filling. We can calculate the added mass for your machine.
Will Tyrefill Affect Ride Comfort?
Yes. It firms the ride versus air but remains more compliant than solids. Most operators find it a good balance of comfort and stability.
Do I Need Different Wheels For Solids?
Often yes. Solids and press‑ons need specific wheel dimensions and fitment tolerances. We can specify and supply wheels that fit first time.
Does Liquid Ballast Stop Punctures?
No. Ballast only changes weight distribution and stability. It does not protect against nails, rebar or sharp debris.
Can You Fit On Site?
Yes. Fieldens OTR Ltd provides nationwide on‑site fitting and workshop services under ISO 9001 controls to minimise downtime.
