About CEAT Specialty Tyres
CEAT Specialty tyres houses a team of industry professionals dedicated to publishing accurate, well-researched and practical content on agricultural and OTR tyres. Our editorial team reviews every article for accuracy, clarity and relevance, using trusted sources and current industry best practices.
Choosing between TR, SM and ND solid tyres for skid steer loaders comes down to one factor: the surface you operate on most. TR (traction) tread suits rough, off-road terrain. SM (smooth) tread is built for warehouse and paved floors. ND (non-directional) tread balances forward and reverse traction on mixed job sites.
Skid steer loaders work in tight, high-torque environments where tyre choice directly affects grip, heat build-up and machine stability. Picking the wrong tread pattern leads to faster wear, poor traction, or unnecessary floor damage.
This guide breaks down CEAT Specialty's LiftPro-S SKS range (SKS TR, SKS SM and SKS ND) using verified specifications, so operators and tyre dealers can match the right solid tyre to the right job in minutes.
Key Takeaways:
- SKS TR: High-traction lug tread for rough, uneven, outdoor terrain
- SKS SM: Smooth tread for maximum floor grip with zero surface marking
- SKS ND: Non-directional block tread for balanced multi-directional traction
- All three use modern aperture design for reduced heat build-up during long duty cycles
What Are the Different Tread Patterns for Skid Steer Solid Tyres?
Skid steer solid tyres from CEAT Specialty come in three tread families, each engineered for a specific working condition.
- TR (Traction): Deep, aggressive lugs for off-road grip
- SM (Smooth): Flat, low-profile tread for smooth-floor stability
- ND (Non-Directional): Multi-angled block pattern for even traction in both directions
Each pattern is built on the same solid resilient construction, using high-quality natural rubber for cut and chip resistance - making them ideal construction and industrial tyres in the solid range.
LiftPro-S SKS TR: When to Choose High-Traction Tread
Choose SKS TR when your skid steer regularly operates on unpaved, rocky, or uneven ground.
Key features:
- High-traction tread for strong off-road capability
- Modern aperture design that reduces heat build-up
- High-quality natural rubber compound for cut and chip resistance
Best for: construction sites, landscaping, demolition and agricultural terrain where grip on loose or irregular surfaces matters more than floor protection.

36x14-20 | 7.50-20 | 920 (36.2) | 330 (13) | 5605 (12 |
LiftPro-S SKS SM: When to Choose Smooth Tread
Choose SKS SM when the loader spends most of its time on finished floors, concrete, or indoor surfaces.
Key features:
- Smooth tread pattern for excellent grip on smooth floors
- Modern aperture design for reduced heat build-up
- High-quality natural rubber for durability
Best for: warehouse floor work, indoor material handling and applications where surface protection and low rolling resistance are priorities.

LiftPro-S SKS ND: When to Choose Non-Directional Tread
Choose SKS ND when the skid steer switches frequently between forward and reverse, or works across mixed terrain (part paved, part rough ground).
Key features:
- Non-directional tread optimised for forward and reverse traction
- Modern aperture design for reduced heat build-up
- High-quality natural rubber for cut and chip resistance
Best for: general-purpose sites, mixed-terrain operations and fleets that need one tyre to handle varied ground conditions without swapping.

TR vs SM vs ND: Side-by-Side Comparison by CEAT Specialty Tyres
| Feature | SKS TR | SKS SM | SKS ND |
Tread type | High-traction lug | Smooth | Non-directional block |
Best surface | Rough/off-road | Smooth/paved | Mixed terrain |
Directional traction | Forward-focused grip | N/A (low profile) | Balanced forward & reverse |
Floor marking risk | Higher on finished floors | Lowest | Moderate |
What Do Apertures Do on Skid Steer Solid Tyres?
Apertures are engineered sidewall voids drilled into the tyre body to improve cooling and cushioning. All three SKS patterns (TR, SM, ND) are available with or without apertures.
- With apertures: better heat dissipation during long, high-load duty cycles; added cushioning for operator comfort
- Without apertures: solid sidewall for maximum load stability where heat build-up is less of a concern
Choose the aperture variant if the loader runs multiple shifts per day or carries heavy attachments continuously.
Final Thoughts
Matching tread pattern to terrain is the single biggest factor in solid tyre performance and lifespan on skid steer loaders. Use TR for rough outdoor ground, SM for smooth indoor floors and ND when the machine needs balanced grip across mixed conditions.
