The Bobcat T550 currently has two active rubber-track widths in TrackTECH's live catalog: 320x86x49 and 400x86x49. Both use 86 mm pitch and 49 links, so width is the main track-size variable.
Bobcat T550 track sizes
| Size | Width | Pitch | Links |
|---|---|---|---|
| 320x86x49 | 320 mm | 86 mm | 49 |
| 400x86x49 | 400 mm | 86 mm | 49 |
320mm vs 400mm — which should you buy?
Use the width that matches the machine's verified setup. The 400 mm option increases footprint and flotation; the 320 mm option keeps the machine narrower. But width is a fitment decision before it is a performance decision.
Do not change widths solely because both options appear in the catalog. Read the current track marking and confirm clearance / machine configuration first.
What tread should you choose?
| Primary surface | Good starting point |
|---|---|
| Hard pack / asphalt / concrete | C-Block or block-style tread |
| Mixed dirt and gravel | Zig-Zag or Staggered Block |
| Mud, snow, soft ground | Multi-Bar or open traction pattern |
| Severe loose terrain | Aggressive / X-Terrain where available |
Verify the undercarriage too
Before installing new rubber, inspect the sprockets, idlers, rollers, tensioner and frame alignment. Use the pre-install CTL undercarriage checklist.

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.
