ASV PT-70 Multi-Bar Rubber Tracks | 457x101.6x50
Heavy-duty 457x101.6x50 aftermarket replacement rubber tracks for the ASV PT-70. The 18-inch footprint and Multi-Bar tread are built for dependable traction, flotation, stable travel, and controlled ground contact across dirt, mud, snow, turf, packed soil, and mixed jobsites. This MWE/TNT replacement belt uses steel-cord reinforcement and is not an ASV genuine polycord track.
Built Around ASV Posi-Track Performance
ASV's Posi-Track undercarriage is designed around internal positive drive, multiple ground-contact points, suspension, and rubber-on-rubber wheel-to-track contact. That architecture is intended to maintain traction, flotation, low ground pressure, ride quality, and stability across uneven terrain, making correct belt geometry and dependable drive-lug engagement especially important.
Multi-Bar Tread Performance
The Multi-Bar pattern creates repeated cross-ground traction edges for steady grip and frequent surface contact. It is suited to landscaping, grading, site preparation, utility work, snow, dirt, mud, and turf-adjacent applications where predictable steering, cleanout, and smoother travel are important.
ASV Genuine vs. This Aftermarket Track
ASV genuine Posi-Track belts are engineered without a steel core and use flexible embedded high-tensile polycord. The MWE/TNT track sold on this page is constructed differently, using continuous joint-less steel cords inside the belt for heavy-duty reinforcement. It is a purpose-built aftermarket replacement, not an ASV genuine track.
Heavy-Duty Aftermarket Construction
Continuous steel-cord reinforcement supports belt strength under repeated steering, travel, pushing, and load cycles. Premium low-abrasion rubber compounds are designed to resist cuts, tearing, chunking, edge damage, and premature wear while maintaining useful flexibility and ride quality.
Undercarriage & Track Life
Inspect drive sprocket rollers, internal drive-lug contact surfaces, roller wheels, idlers, guide areas, debris buildup, alignment, and track tension before installation. Worn components, packed material, or incorrect tension can accelerate belt wear and reduce service life. Set final tension to the applicable service specification for the installed replacement track.
Warranty & Support
Nationwide fulfillment is available, backed by a 24-month TrackTECH warranty against manufacturing defects and application support when needed.

ENGINEERED FOR THE JOBSITE
Built Tough
Heavy-duty replacement rubber tracks engineered for compact track loaders, tracked skid steers, mini excavators, mini track loaders, and demanding construction equipment applications.
-
100% Virgin Rubber
Engineered to resist chunking, tearing, and cutting in harsh, abrasive environments.
-
Continuous Steel Cords
Jointless internal cable architecture eliminates structural weak points and maximizes overall tensile strength.
-
Drop-Forged Links
Precision heat-treated guide lugs ensure exact sprocket engagement and prevent de-tracking under heavy side-loads.
-
Corrosion Resistant
The internal steel framework is fully encapsulated to prevent oxidation, rust, and moisture penetration.
-
Reinforced Sidewalls
Extra-thick vulcanized rubber and tapered edge profiles protect against curb slashing and lateral impacts from jobsite debris.
-
Low-Vibration Tread
Optimized lug spacing and pitch geometry absorb shock, reducing undercarriage wear and minimizing cabin vibration.
