Rubber Track Fitment & Pattern Guide
Measure. Match. Choose the Right Rubber Track.
Find the right rubber track by confirming Width × Pitch × Links / Drive Lugs, identifying the undercarriage style, and then choosing a tread pattern offered for that exact fitment. Questions? Call 800-966-6640.
Start Here: The 3 Numbers You Need
1Width (mm) - total track width across the tread, edge to edge.
2Pitch (mm) - center-to-center distance between consecutive inner drive points.
3Links / Drive Lugs (#) - total count around the inside of the track.
Fitment shortcut: If your current track still has a molded size, copy it exactly. If not, measure width and pitch in millimeters and count every link or drive lug before ordering.
How to Read & Measure Rubber Track Size
1) Width (W)
Measure the overall track width from one outside tread edge to the other in millimeters.
2) Pitch (P)
Measure center-to-center between two consecutive inner drive points. On steel-link tracks, use the steel inserts or drive links. On coreless tracks, use the molded rubber drive lugs.
3) Links / Drive Lugs (L)
Mark one starting point, then count every steel link or rubber drive lug around the full inside circumference of the track.
UST Tip: Many tracks have the size stamped or molded on the inner surface. Clean the rubber and look for a marking such as 450x86x52. Copy the complete marking before ordering.
Find Your Machine
Browse current UST rubber track listings by machine type, brand, and model. Start with the machine family below, then confirm the exact track size and undercarriage details before ordering.
Important: Finding your model gets you to the correct machine family, but exact fitment can still vary by serial number, undercarriage style, width, pitch, link or drive-lug count, and other machine-specific details. Always verify the individual product fitment before ordering.

Track Loaders: CTLs & Mini Track Loaders
Track-loader fitments in the current catalog span several pitch and link-count families. Do not assume that all 86 mm tracks share the same link count, or that every machine in a brand uses the same pitch.
86 mm Pitch Examples
Bobcat T590: 320x86x49 or 400x86x49.
Bobcat 864: 320x86x52, 400x86x52, or 450x86x52.
Bobcat T250: 450x86x55.
JCB 260T: current 450 mm examples use 450x86x56.
100 mm Pitch Examples
Takeuchi TL10, TL140, and TL240 examples use 450x100x48.
Takeuchi TL12, TL150, and TL250 examples use 450x100x50.
A 100 mm-pitch system indexes differently than an 86 mm-pitch system. Match the exact machine configuration rather than substituting by width.
Mini Track Loader Examples
Bobcat MT100 is represented with multiple 72 mm-pitch options, including 180, 230, and 250 mm widths depending on the exact track configuration.
Ditch Witch SK1050 examples include 180x72x44 and 230x72x44.
Ditch Witch SK1550 has a current S-Bar example at 265x72x52.
Why Drive Style Matters
The current Toro Dingo TX1000 listing illustrates why model name alone is not enough:
- Sprocket-driven: 150x86x67
- Bogey-driven wide: 250x88x37
- Bogey-driven narrow: a separate 88 mm-pitch configuration is also listed
Before ordering: identify the drive system first, then confirm width, pitch, and link / drive-lug count.
- Pitch and count are fitment dimensions: both must index correctly with the drive system.
- Width is not automatically interchangeable: verify the exact product fitment and machine clearance before changing width.
- Pattern comes last: compare only the tread patterns offered for the confirmed machine and size.
Mini Excavators
Mini-excavator tracks use the same basic Width × Pitch × Links format, but guide profile, roller / flange arrangement, and available tread patterns vary by model.
Current Catalog Size Examples
Bobcat E10: 180x72x39.
Bobcat E14: current listings include 180x72x41; an L-Lug listing uses 200x72x41.
Gehl Z17: 230x72x46.
These are fitment examples from current product listings, not universal mini-excavator sizes.
Mini-Excavator Fitment Checklist
- Confirm the exact machine model and variant.
- Verify width, pitch, and link count.
- Confirm roller / flange style.
- Verify the inner guide height and profile.
- Confirm adequate adjuster range for proper tension.
- Choose tread only after the fitment is confirmed.
Crawler Carriers, Dumpers, Pavers & Other Tracked Machines
The current catalog also includes crawler carriers, compact dumpers, directional-drilling machines, asphalt pavers, and other specialized tracked equipment. These machines can use very different drive systems and track constructions, so the exact model and track dimensions matter.
Crawler Carrier Example
Morooka MST1500 and several MST1500-family crawler listings use 700x100x98 Straight Bar tracks.
These crawler tracks use heavy-duty center drive components where the sprocket engages. Confirm model variations before ordering.
Asphalt Paver Example
Cat AP1055 family listings include track configurations such as 460x225x36 and 470x152.4x53.
Different track constructions can exist within the same machine family, so use the exact listing and dimension set.
Agricultural Rubber Tracks
Agricultural rubber tracks can use wider belts and larger pitch dimensions than compact construction equipment. Match the exact tractor / harvester family, width, pitch, and link count shown for the product.
John Deere 8000T Family Example
John Deere 8000T listings include:
457x152.4x54635x152.4x54762x152.4x54
Fitment rule stays the same: do not choose by width alone. The pitch, link count, drive system, and machine family must all agree with the replacement track.
Choosing a Rubber Track Tread Pattern
Fitment comes first. Once the machine, dimensions, and undercarriage are confirmed, compare only the patterns offered on the compatible product.
Pattern availability is part-number specific. The four images below use confirmed UST pattern imagery. Do not use a tread photo by itself to determine fitment.

How to Be Sure Your New Track Matches
- Start with the exact machine model and use Equipment Search or the machine index above.
- Find the molded or stamped size on the inside of your current track and copy the complete marking.
- Measure and count if the marking is missing: width (mm), pitch (mm), and links / drive lugs.
- Verify the undercarriage: sprocket or drive style, roller / flange style, inner guide profile, and any serial-number or configuration notes.
- Confirm clearance before changing track width.
- Choose tread pattern only from the options offered for the confirmed fitment.
- Replace tracks in pairs when practical on CTLs and MTLs to help keep side-to-side wear more even.

Rubber Track Fitment FAQ
What do the three numbers mean, such as 450x86x52?
They represent Width (mm) × Pitch (mm) × Links / Drive Lugs (count). Width is the overall track width, pitch is the center-to-center distance between consecutive inner drive points, and the final number is the total count around the track.
Where do I find my rubber track size?
Look for a stamped or molded size on the inside surface of the track. If it is unreadable, measure the width and pitch in millimeters and count the links or drive lugs around the track.
Does finding my machine in the catalog index guarantee every track shown will fit?
No. The machine index confirms that the model is represented in the current catalog, but fitment can still vary by serial number, undercarriage style, width, pitch, link / drive-lug count, and other machine-specific details. Verify the exact product fitment before ordering.
Will a wider track affect fitment?
Yes. A different width changes machine clearance and ground contact even when pitch and link count remain the same. Match the drive dimensions first and confirm frame, roller, and fender clearance before changing width.
Why can the same machine family use different track sizes?
Some machine families have multiple undercarriage styles, serial-number breaks, optional widths, or drive systems. The current Toro Dingo TX1000 listing, for example, includes both sprocket-driven and bogey-driven configurations, so the drive style must be identified before ordering.
Which tread pattern is best?
Choose only from patterns available for your confirmed fitment. C-Lug is a strong mixed-terrain choice; Block is a general-purpose hardpack and pavement option; Split Bar balances bidirectional traction and ride quality; Q-Tread provides multi-directional traction; Turf reduces ground disturbance; and Z-Lug is intended for demanding traction conditions such as steep grades, snow, and ice.
What are non-marking rubber tracks for?
Non-marking variants use a rubber compound intended to reduce black marks on finished surfaces. They are useful for indoor construction, warehouses, public venues, and other surface-sensitive applications when a compatible non-marking track is offered for the machine.
Should I replace both tracks at the same time?
On compact and mini track loaders, replacing tracks in pairs when practical can help keep side-to-side wear and traction more consistent.
Any installation or break-in tips?
Inspect sprockets, rollers, idlers, and related undercarriage components before installation. Set track tension according to the machine manual and re-check tension after initial use.
