The CAT 259D3 has two confirmed rubber-track configurations in TrackTECH's governed fitment catalog. The primary configuration is 320x86Bx53. A 400x86Bx53 wide-track configuration is also cataloged, but changing to that width requires machine configuration before ordering.
Need CAT 259D3 tracks now?
Cataloged sizes: 320x86x53, 400x86x53
That distinction matters. The 400mm track is not a universal upgrade simply because the pitch and link count match. Start with the size molded into the track already on your machine, then confirm the undercarriage configuration before changing widths.
CAT 259D3 Track Size
| Configuration | Track Size | TrackTECH Status |
|---|---|---|
| Primary | 320x86Bx53 | cataloged, release-ready |
| Wide alternative | 400x86Bx53 | cataloged; confirm your machine before changing width |
Both configurations use an 86mm pitch, 53 links, and a B-guide track family. Width is the variable. If the old track is readable, use that marking as your first check.
Can You Put 400mm Tracks on a CAT 259D3?
Sometimes, yes—but verify first. TrackTECH's current fitment graph contains a confirmed 400x86Bx53 alternative for the 259D3. Because that alternative is flagged for machine configuration, it should not be treated as permission to swap every 259D3 from 320mm to 400mm without checking the installed track and machine configuration.
If you are choosing between available widths, see our wide vs. narrow CTL track guide for the flotation, transport-width, and ground-pressure trade-offs.
What the Size Means
- 320 or 400 = track width in millimeters.
- 86 = pitch in millimeters.
- B = Block/B-guide family.
- 53 = total link count.
Pitch, links, and guide geometry are fitment dimensions—not preferences. A track that is merely close in circumference or width is not automatically interchangeable.
Choosing a Tread Pattern
Choose tread only after confirming the correct size. Different patterns solve different jobsite problems; width controls footprint while tread controls how that footprint engages the surface. Compare current options in our C-Block vs. Zig-Zag vs. Multi-Bar guide.
What to Inspect When Replacing Tracks
- Drive sprocket teeth for hooking or uneven wear
- Front and rear idlers for flange wear or play
- Bottom rollers for leaks, flat spots, or binding
- Track alignment and final tension
New rubber installed on a badly worn undercarriage can wear prematurely, so a track change is the right time to inspect the entire system.
Frequently Asked Questions
What size track does a CAT 259D3 use?
The current TrackTECH governed fitment is 320x86Bx53 primary, with 400x86Bx53 as a cataloged alternative that requires machine configuration before changing widths.
Is 400x86x53 a direct replacement for every CAT 259D3?
No. It is an alternative in the fitment catalog, but the machine configuration must be verified before using it in place of the primary 320mm configuration.
Can I choose tread pattern independently of track size?
You can choose among tread patterns offered in your listed size. Width, pitch, link count, and guide family still have to match the machine.

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.
