Bobcat’s Skid Steer Evolution and Wheel Design
Bobcat, a brand synonymous with compact equipment, revolutionized the construction and landscaping industries with its skid steer loaders. Since the 1960s, Bobcat has produced millions of units globally, with models ranging from the early M-series to the modern S-series. These machines rely on rugged wheel assemblies to deliver torque, traction, and stability across varied terrain.
Most Bobcat skid steers use 8-lug wheels with a bolt circle diameter of 8 inches and a center bore of approximately 6 inches. The standard tire size for mid-range models like the S185 or S650 is 10-16.5, mounted on rims typically 8.25 inches wide. These specifications are critical when sourcing replacements, as incorrect offset or bore dimensions can lead to premature bearing wear or unsafe handling.
Why Dealer Pricing Can Be Prohibitive
OEM Bobcat wheels, while high-quality, often come with steep price tags. Dealers may charge upwards of $250 per wheel, citing manufacturing standards, warranty coverage, and logistics. For small contractors or owner-operators, this cost can be difficult to justify—especially when replacing all four wheels or outfitting a second machine.
The high markup is partly due to centralized distribution and branding. Bobcat, now under Doosan Group ownership, maintains strict control over parts channels. While this ensures consistency, it limits competition and inflates prices for basic components like rims.
Exploring Alternative Sources for Replacement Wheels
Fortunately, the aftermarket offers several viable options for Bobcat-compatible wheels. Local tire shops, agricultural suppliers, and industrial salvage yards often stock generic 8-lug skid steer rims that meet or exceed OEM specifications.
Common alternatives include:
In South Dakota, a contractor operating a Bobcat S185 needed to replace two damaged wheels after a curb impact. The local dealer quoted $500 for the pair, prompting a search for alternatives. A nearby tire shop offered compatible rims for $70 each, originally intended for a Case skid steer but with identical specs. After confirming bolt pattern and offset, the contractor installed the wheels without issue. The machine performed flawlessly, and the savings were redirected toward hydraulic hose replacements.
This experience underscores the value of cross-referencing specifications and thinking beyond brand labels.
Recommendations for Buyers Seeking Cost-Effective Solutions
To ensure safe and economical wheel replacement:
Conclusion
Bobcat skid steer wheels are more than just round metal—they’re the interface between machine and terrain. While dealer-sourced rims offer peace of mind, the aftermarket provides practical alternatives for budget-conscious operators. By understanding bolt patterns, rim dimensions, and load requirements, buyers can confidently source replacements that perform without compromise. In the world of compact equipment, smart sourcing keeps machines rolling and businesses thriving.

Fortunately, the aftermarket offers several viable options for Bobcat-compatible wheels. Local tire shops, agricultural suppliers, and industrial salvage yards often stock generic 8-lug skid steer rims that meet or exceed OEM specifications.
Common alternatives include:
- Aftermarket steel rims from brands like Titan or Carlisle
- Used take-off wheels from retired fleet machines
- Agricultural implement wheels with matching bolt patterns
- Custom-fabricated rims from welding shops with CNC capabilities
- Bolt pattern: 8 on 8 inches
- Center bore: 6 inches minimum
- Rim width: 8.25 inches for 10-16.5 tires
- Offset: Typically zero or slightly positive for Bobcat loaders
- Load rating: Minimum 3,000 lbs per wheel for mid-size machines

Recommendations for Buyers Seeking Cost-Effective Solutions
To ensure safe and economical wheel replacement:
- Measure existing wheel dimensions before purchasing
- Avoid rims with excessive rust, bent flanges, or mismatched lug holes
- Confirm load rating and material thickness for structural integrity
- Use thread locker on lug nuts and torque to manufacturer specs
- Recheck lug nut torque after 10 hours of operation
- Keep one spare rim on hand for emergency repairs
