The best skid steer tire construction depends on the problem you need to solve. If an otherwise suitable machine rarely suffers punctures, replacing its pneumatic tires with a flat-resistant system may not repay the additional cost. If sharp debris repeatedly stops an essential job, the calculation can change quickly. Ride, traction, fitment, operating weight and the cost of interrupted work all belong in the decision.
For Canadian farms and property operations, there is an additional complication: one loader may work on concrete, gravel, soft spring ground and packed snow during the same year. Eliminating flats does not automatically produce the right traction on each surface. Begin with the actual work calendar and failure history, then compare specific tire products rather than treating “solid” or “air-filled” as a complete specification.
Four constructions that should not be confused
| Construction | What supports the load | Main buying question |
|---|---|---|
| Pneumatic | An inflated tire structure | Does the current combination of traction, ride and puncture exposure suit the work? |
| Polyurethane-filled pneumatic | The tire casing with a cured fill replacing its air | Can the approved fill and casing solve costly punctures without creating an unsuitable package? |
| Solid or aperture solid | A designed solid tire structure, sometimes with openings for deflection | Does this specific design suit the surface, speed, load and desired ride? |
| Airless spoke assembly | A purpose-designed tread, spoke and wheel system | Is there an approved assembly for the machine and its duty? |
These categories describe construction, not a ranking. There are different products within each. A tire intended for abrasive hard-surface work and one intended for off-road traction may behave differently even when both are pneumatic or both are solid. Start with construction only after identifying the surface and operating demands.
Pneumatic tires: know what is working before changing it
If your loader currently performs the job well, record that baseline. Note the tire model, size, operating hours, tread condition and puncture history. A replacement decision is much clearer when it compares a proposed improvement with measured experience rather than dissatisfaction after a single inconvenient flat.
Pneumatic construction requires correct inflation and condition monitoring. The pressure must follow the applicable tire and machine requirements; this guide does not prescribe a universal skid steer pressure. Reducing pressure by guesswork to seek a softer ride is not a substitute for a compatible tire setup.
Separate tread wear from puncture failure. If tires reach their usable wear limit without interruption, a puncture-focused upgrade is solving a problem you may not have. If tires are discarded early because of repeated sidewall or tread damage, examine both the tire choice and the worksite. The correct response may include removing debris or changing the route, not only buying a different construction.
Foam-filled usually means a polyurethane core, not repair foam
In equipment discussions, “foam-filled” often refers to professionally filling a pneumatic casing with a polyurethane material. Carlisle TyrFil describes its product as replacing the air and curing into an elastomer core. That is different from adding a puncture sealant or using household expanding foam. It is a specified tire-service process, not an improvised repair.
The fill formulation matters. Carlisle offers different hardness formulations for different duties. Therefore, statements that every filled tire rides identically are too broad. Assess the particular casing, fill and application together. Keep manufacturer performance claims separate from a demonstration on your own machine and route.
Ask for the resulting assembly weight, approved application, processing time and replacement procedure in the quote. Plan when the loader will be unavailable and whether a spare arrangement is needed. The tire still has a casing and tread to inspect; eliminating loss of air does not make it immune to every kind of damage.
A fill conversion deserves special attention if the machine is transported often. The transport plan should use the actual resulting configuration. Do not assume that added tire mass increases the loader’s approved payload. Capacity remains governed by the machine manufacturer’s permitted arrangement.
Solid tires are a family of designs
A solid tire eliminates reliance on inflation pressure, but it still needs to match the duty. Solid construction can include apertures designed to allow deflection. Camso’s technical literature, for example, distinguishes aperture designs from full-solid designs. That distinction is enough to reject a blanket assumption that every solid tire has the same ride or footprint.
Ask which surface the quoted tread is intended for and how the product is rated for the intended speed and load. Also establish whether the wheel is reusable, what replacement involves and what local service equipment is required. Two quotes labelled “solid tires” may describe materially different ownership arrangements.
For a loader that spends long periods moving between work areas, a demonstration of travel behaviour matters. For one that stays near a fixed handling point, another set of priorities may dominate. Neither situation can be reduced to a universal claim that solids are always economical or always uncomfortable.
Airless spoke tires are a separate alternative
Michelin’s X TWEEL SSL uses a purpose-designed spoke structure rather than a conventional pneumatic casing filled with material. Michelin offers skid-steer versions for different surface applications. Compare the exact assembly and fitment, not just the familiar size notation on another tire.
For a buyer, the useful questions are practical: does an approved version fit the machine, does its tread suit the route, what are its load and speed limits, and what support is available for inspection and eventual replacement? Manufacturer claims about wear life should not be converted into a guaranteed number of hours for a Canadian farm without matching conditions and evidence.
An airless system addresses inflation-related downtime. It does not make the machine independent of ground conditions, attachment load or operating instructions. Retain ordinary inspection and condition monitoring even when there is no air pressure to check.
Define the failure before choosing the cure
Use a simple incident log for the current tires. Record the date, hours, location, type of damage, repair cost and time lost. Add what the machine was doing and whether the job could continue with another machine. A puncture during a flexible cleanup task has a different operational consequence from a puncture that stops an essential daily process.
| Observed problem | What to investigate first |
|---|---|
| Repeated damage in one area | Debris source, route and site housekeeping, alongside tire protection |
| Fast wear during hard-surface turning | Tread application, operating pattern and condition monitoring |
| Poor traction in a particular season | Surface, tread and approved seasonal equipment |
| Unacceptable ride on travel routes | Specific construction, machine setup, route and demonstration conditions |
| Occasional inexpensive punctures | Repair and spare strategy before a major conversion |
This is a diagnostic purchase process, not a claim that every listed problem has one cause. For example, a tire change cannot repair an unsuitable route, and route cleanup cannot eliminate every unavoidable sharp object. The best plan may combine a moderate equipment change with a better worksite routine.
Fitment: size is only the beginning
Before accepting a quote, identify the exact loader model and serial configuration. Record the existing tire and wheel identification, then ask for written confirmation of the proposed assembly’s compatibility. Wheel mounting, offset, clearance and the resulting machine width matter alongside tire size.
Check the attachment envelope after a change. A different overall width can affect whether the bucket clears the tire path, whether the machine fits a doorway and how it loads onto transport equipment. A change that solves punctures but creates an access problem may be a poor trade.
Load and speed ratings also need to match the actual duty. The average weight divided by four is not a complete tire selection method because wheel loads change with the machine’s load position and operation. Use the manufacturer-approved application rather than inventing a new rating from a simple average.
Camso’s maintenance guidance advises against mixing tire constructions and profiles on a machine. Treat a proposed partial conversion as a compatibility question to resolve before installation. Tire mounting and fill work belong with appropriately trained service personnel and suitable equipment.
Over-the-tire tracks can change the answer
If you use or plan to use over-the-tire tracks, check that compatibility before choosing a tire conversion. Camso specifically states that it does not recommend foam-filled or solid tires with its OTT systems because of the additional pressure imposed on the track. That is a manufacturer-specific restriction to respect, not a claim that every track product in the world has identical instructions.
Give the track supplier the complete proposed tire and wheel setup. Clearance, dimensions and the permitted combination should be confirmed in writing. Do not buy tires first and assume that tracks can be added later without changing anything else.
If over-the-tire tracks are becoming a permanent requirement because the loader routinely works on soft ground, revisit the machine choice. The skid steer versus compact track loader guide addresses that broader question. A tire-construction decision should not hide a mismatch between the machine and its main terrain.
Canadian seasons: puncture resistance is not winter traction
Separate winter grip from flat resistance. A construction that eliminates an air-loss puncture does not by itself establish performance on ice, packed snow or a wet concrete surface. Evaluate the specific tread and approved application, and avoid declaring one entire construction category the best winter tire without suitable evidence.
Describe the actual route when requesting a recommendation: outdoor lanes, cleared pavement, barn entrances, gravel and places where snow becomes compacted. Include the attachment and the work pattern. A loader pushing snow across an open lot faces a different task from one carrying material between sheltered buildings.
For spring, distinguish traction from support. A tire may grip while the ground still cannot adequately support the loaded machine. Repeated rutting can indicate a route or timing problem rather than an invitation to keep changing tread. Compare a prepared route, revised schedule or different machine where the job justifies it.
Keep seasonal comparisons fair. A new tire tested on dry ground should not be credited with solving a problem observed only during thaw. Record conditions and revisit uncertain performance in the relevant season before treating a purchase assumption as a proven result.
A cost-per-hour example with explicit assumptions
The following Canadian-dollar amounts are fictional planning inputs, not market prices or expected tire lives. Their purpose is to show the calculation. Obtain actual installed quotes and use your own service history.
Assume two compatible setups are being compared over 1,000 productive hours. Setup A costs C$2,400 installed, incurs C$900 in tire-related repairs and causes six hours of downtime valued at C$150 per hour. Setup B costs C$4,800 installed, incurs C$200 in other tire service and causes one hour of downtime at the same assumed cost.
| Cost over the comparison period | Setup A | Setup B |
|---|---|---|
| Installed purchase | C$2,400 | C$4,800 |
| Service and repairs | C$900 | C$200 |
| Downtime | 6 × C$150 = C$900 | 1 × C$150 = C$150 |
| Total | C$4,200 | C$5,150 |
| Cost per productive hour | C$4.20 | C$5.15 |
Under these assumptions, the more expensive setup does not recover its premium. It may still offer another valuable benefit, but the puncture-cost argument alone has not proved it cheaper. This is why a flat-resistant construction should not be described as automatically paying for itself.
Change the downtime assumption
Now assume A loses 20 hours and B still loses one, with other inputs unchanged. A’s total becomes C$6,300, or C$6.30 per productive hour. B remains C$5.15. The ranking reverses because interrupted work became more expensive.
The purchase premium is C$2,400. The assumed repair saving is C$700, leaving C$1,700 to recover through reduced downtime. At C$150 per hour, B needs to avoid about 11.3 more downtime hours than A over the period to break even. This simplified result excludes financing, residual value and any difference in usable life.
Use a realistic downtime value. Do not automatically substitute the full customer billing rate if the business does not actually lose that revenue. Count costs that genuinely change: idle labour, replacement rental, delayed essential work or recoverable scheduling time. Avoid counting the same loss in both labour and lost revenue without checking the overlap.
When tire life differs, use the same accounting basis
The previous example deliberately uses an equal comparison period and treats installed cost as consumed over that period. Real products may have different remaining life. If one retains substantial usable tread at the end, charging its entire purchase cost while giving no residual credit can distort the result.
Choose a common operating horizon and estimate replacements, service and remaining value consistently. Then repeat the calculation with conservative and optimistic life assumptions. A decision that changes with a small adjustment needs more evidence; a decision that remains favourable across a broad plausible range is less sensitive to prediction error.
Record why a tire leaves service. Wear, damage, changed application and machine sale are different outcomes. “Lasted 1,000 hours” means little without knowing whether the tire was worn out, destroyed by an incident or still usable when the loader was sold.
A practical buying sequence
- Define the main surfaces, loads, travel distances and seasonal conditions.
- Collect current tire costs, failures and productive hours.
- Identify the exact machine, wheels and any over-the-tire track requirement.
- Request complete installed quotes for compatible alternatives, including fill or assembly details.
- Check the resulting weight, dimensions, rated application and service arrangements.
- Demonstrate ride, visibility and task performance under comparable approved conditions.
- Calculate cost per productive hour and test uncertain assumptions.
- Keep a record after installation so the next replacement uses evidence.
For a model-based starting point, the Bobcat S650 and Bobcat S770 illustrate wheeled machines a buyer might be evaluating. Their model identity alone does not approve a replacement tire. Use the actual machine’s documentation and the tire supplier’s fitment confirmation.
Likewise, changing tires does not authorise a higher payload. Review rated operating capacity and tipping load if added weight or a different stance is being presented as a capacity upgrade. Keep the approved machine rating separate from assumptions about stability.
Questions that often remain
Should every farm loader have solid tires?
No. A low-puncture operation may gain little from a major conversion, while ride, fitment or seasonal requirements may favour another setup. Use the actual damage history and work pattern to identify the problem worth solving.
Is polyurethane fill the same as tire sealant?
No. Fill replaces the air and cures into a supporting core. Sealant is a different product with a different purpose. Use the specified professional process and a suitable casing; do not improvise a fill material.
Can a flat-resistant tire still need replacement?
Yes. Tread wear, structural damage and application limits still matter. “No air to lose” is not equivalent to unlimited service life or immunity from damage.
Will the heavier setup automatically lift more?
No. Added assembly mass is not a manufacturer-approved capacity increase. Confirm the permitted configuration and handling limits instead of inferring a new payload from weight alone.
Can I compare quotes without an exact tire model?
Only superficially. The construction label leaves out tread, rating, assembly, fill formulation, installation and service support. Request enough detail to know that both quotes solve the same task.
When should I keep the current pneumatic setup?
When it meets the job, failures are infrequent and a compatible alternative does not offer enough measurable benefit. Improving inspection, spare availability or the route may be the more economical first action.
