Bobcat T-Series fitment cannot be reduced to one width per frame size. TrackTECH's governed catalog contains several models with multiple cataloged widths, plus a few applications that still require configuration-specific fitment before they are safe to release by model alone.
Bobcat T-Series Track Size Chart
| Model | Current TrackTECH fitment | What to know |
|---|---|---|
| T550 | 320x86B49 primary; 400x86B49 alternative | 400mm is configuration-specific |
| T590 | 320x86B49 or 400x86B49 | Both cataloged; configuration-specific |
| T595 | 320x86B49 / 400x86B49 candidates | Supplier cross-reference only; not release-ready by model alone |
| T630 | 320 / 380 / 400 / 450 x 86B x 52 | cataloged alternatives; |
| T650 | 320 / 380 / 400 / 450 x 86B x 52 | cataloged alternatives; |
| T740 | 400x86B55 or 450x86B55 | cataloged; configuration-specific |
| T750 | 400x86B55 or 450x86B55 | cataloged; configuration-specific |
| T770 | 400x86B55 or 450x86B55 | cataloged; configuration-specific |
| T76 | 320x86B53 primary; 400x86B53 and 450x86B53 alternatives | configuration-specific |
| T86 | 450x86B58 | cataloged primary |
| T870 | 450x86B58 suspension mount; 450x86B60 torsion mount | Undercarriage configuration is critical |
The T870 Exception Matters
The Bobcat T870 is a good example of why a model-only chart can be dangerous. TrackTECH has a cataloged 450x86B58 primary fitment for the suspension-mount configuration and a cataloged 450x86B60 option for the torsion-mount configuration. Do not substitute one for the other without identifying the undercarriage.
Why Some Bobcat Models Show Multiple Widths
Several T-Series machines have more than one available width with the same pitch and link count. That does not mean every machine should be converted to every listed width. Treat alternative widths as governed fitment options that still require the installed track or undercarriage to be checked.
Bobcat Track Options
- Match width, pitch, links, and guide family.
- Check any undercarriage-specific notes such as T870 torsion versus suspension mount.
- If a fitment is marked configuration-specific, verify before ordering rather than relying on a generic web chart.
After the size is confirmed, choose tread for the jobsite using our tread-pattern guide. For machine-level confirmation, use the Rubber Track Finder or call (850) 816-7898.

Quick Buying Answers
Which rubber track rides the smoothest? For a verified fitment that offers it, Multi-Bar is usually the first tread to compare when lower vibration and smoother travel matter most.
Which track lasts longest on pavement? On asphalt and other hard, relatively flat surfaces, Multi-Bar is a strong first choice because it spreads contact across more tread bars. For harsher abrasive work such as broken concrete, rock, or demolition debris, compare a heavier C-Block or Staggered Block pattern instead.
What is the best track for paving? Start with Multi-Bar when ride quality, steady contact, and hard-surface travel are priorities. Confirm that the exact pattern is available for your machine before ordering.
What is the most affordable track? Price depends on the exact width, pitch, link count, guide type, and tread. Once fitment is confirmed, compare the live compatible options rather than changing dimensions just to save money.
What about mud, snow, or soft ground? Zig-Zag is usually the better pattern to compare when cleanout and bite matter more than pavement manners.
