Coats Guide: Maxx 50 vs RC-55
A practical guide to understand why the Maxx 50 exists, how it compares to the RC-55, and when each is the right choice.
What is the Maxx 50 for?
- Entry model on the premium Maxx chassis — same heavy-duty frame & 220V power platform as higher Maxx models.
- Simplified toolset — no helper arm by default; keeps upfront cost and maintenance lower.
- Wider rim width capability — accommodates up to ~16" rim width (typical Maxx platform spec) for broader wheel coverage.
- Dual bead-seating nozzles — fast seating for stubborn tires compared with basic bead jets.
- Upgradeable path — add helper devices later (Robo-Arm / RoboRoller) as your workload grows.
Where the RC-55 shines
- Comes with Robo-Arm helper out of the box, better control on low-profile / XL / tough sidewalls without upgrade spend.
- 115V option & compact footprint: easier drop-in for tight bays and standard electrical service.
- Everyday general repair: proven, simple, and efficient for standard passenger/LT work.
