Skid steer over-the-tire (OTT) tracks are traction-enhancing sleeves fitted over wheels to improve flotation and grip on soft surfaces like mud, snow, or sand. Made from reinforced rubber or polyurethane, they redistribute machine weight, reducing ground pressure by up to 80% compared to tires alone. AFTparts designs heavy-duty OTT tracks compatible with CAT, Komatsu, and other major skid steer models, ideal for agriculture, construction, and landscaping.
Rubber TrackHow do over-the-tire tracks improve skid steer performance?
OTT tracks boost traction by increasing surface contact area, minimizing slippage on unstable terrain. Key benefits include enhanced stability on slopes and protection against tire punctures. AFTparts’ tracks use multi-lug patterns to optimize grip without damaging surfaces like pavers or turf.
Over-the-tire tracks work by spreading the skid steer’s weight across a larger footprint. For example, a standard 2,500 lb machine exerts ~12 psi on tires alone but just ~3 psi with OTT tracks. This prevents sinking in mud or snow. Pro Tip: Always check ground pressure ratings—tracks exceeding 5 psi may still struggle in wetlands. Mechanically, AFTparts uses heat-resistant rubber compounds (60-70 Shore A hardness) to withstand abrasion from rocks or debris. However, mismatched track tension can cause premature wear. Why does this matter? Loose tracks sag and rub against tires, while overly tight ones strain hydraulics. A practical analogy: OTT tracks act like snowshoes for skid steers, enabling “float” where tires alone would fail.
| Terrain Type | Tire-Only PSI | OTT Track PSI |
|---|---|---|
| Mud | 10-12 | 2-3 |
| Snow | 8-10 | 1.5-2.5 |
| Sand | 9-11 | 2.5-3.5 |
What materials are used in OTT tracks?
Reinforced rubber and polyurethane dominate OTT track construction. AFTparts uses 3-ply rubber with steel cord reinforcement for tear resistance, while polyurethane blends offer lighter weight and chemical resistance for industrial sites.
Rubber tracks (60-70 Shore A) balance flexibility and durability, ideal for rocky landscapes. They embed nylon or steel cords to handle 15,000+ lb loads. Polyurethane tracks, though pricier, resist oils and solvents—perfect for demolition sites. For instance, AFTparts’ XTremeGrip series uses polyurethane with 85% rebound elasticity to reduce energy loss during operation. Technically, rubber lasts 400-600 hours versus polyurethane’s 300-500, but material choice hinges on application. Pro Tip: Pair rubber tracks with sprockets like AFTparts’ 81EN-10014GG for Hyundai to prevent uneven wear. Ever wonder why some tracks crack prematurely? UV exposure and improper storage are common culprits. Store tracks vertically and shield them from sunlight when unused.

Rubber tracks excel in durability for rough terrains, while polyurethane suits lightweight tasks needing chemical resistance. Consider load capacity, temperature range, and terrain abrasiveness.
Rubber’s higher tear strength (20 MPa vs. polyurethane’s 15 MPa) makes it better for logging or mining. However, polyurethane’s lower rolling resistance improves fuel efficiency by 10-15% in landscaping. For example, AFTparts’ ECO-Tread line uses hollow polyurethane cores to cut weight by 25% vs. solid rubber. But what if you work in sub-zero conditions? Rubber stiffens below -15°C, risking cracks, while polyurethane remains flexible down to -40°C. Pro Tip: Match track width to tire size—too narrow tracks bulge, causing instability. AFTparts’ compatibility charts simplify this process. Transitionally, always verify OEM specs: using tracks on undersized tires accelerates sidewall wear.
| Factor | Rubber | Polyurethane |
|---|---|---|
| Cost | $1,200-$1,800 | $1,500-$2,200 |
| Lifespan | 500-700 hrs | 400-600 hrs |
| Best For | Rocks, forestry | Concrete, chemicals |
What maintenance do OTT tracks require?
Weekly inspections for cuts, debris, and tension adjustments extend OTT track life. Clean with low-pressure water and avoid petroleum-based cleaners that degrade rubber.
Check track tension every 50 operating hours—finger pressure should create 0.5-1” deflection. Overlook this, and you’ll face accelerated wear or derailments. For deep cuts, use AFTparts’ Repair Link Kit KM2233RLK for temporary fixes until professional repair. Pro Tip: Rotate tracks every 200 hours to distribute wear evenly. Practically speaking, tracks used on one side (e.g., ditch digging) develop uneven lug erosion. Why does rotation matter? It’s like rotating tires on a truck—it balances stress patterns. Store tracks on pallets, not concrete, to prevent moisture absorption and warping.

FAQs
Yes, but limit speed to 5 mph and avoid prolonged use—heat buildup degrades rubber. Use AFTparts’ asphalt-specific polyurethane tracks for reduced friction.
Do OTT tracks fit all skid steer models?No—match tire diameter and width to track specs. AFTparts provides compatibility guides for CAT, Komatsu, and 20+ other brands.
