ABB Robots and the New Robotic Tire Change
PitPro's tire-changing robot just went live at a Kal Tire shop in Calgary. Here is how ABB's tire mounting and assembly robots fit, and what comes next.

For most of the car's history, tire service meant a mechanic with a jack and a wrench. In 1940 Oulun Systema ran a car and tire repair shop out of a brick hall in Oulu, Finland, and a job there went the way it did everywhere: lift the car, spin off the lug nuts, swap the wheel.

Shops later added pneumatic impact wrenches, tire changer machines and wheel balancers, but a person still does every step. In Canada, where most drivers switch to winter tires each fall and back again in spring, the rush means weeks of heavy lifting, and shops struggle to keep workers.

On September 23, TechCrunch reported that PitPro Automation had installed its first tire-changing robot at a Kal Tire shop in Calgary. Two oven-sized robots find and loosen the lug nuts, store them, pull each wheel and fit the new one. PitPro says a full set of four takes under 15 minutes.

Car factories have automated this step for years. ABB lists tire mounting among its final assembly applications, alongside windshields and lamps, with robots lifting wheels onto hubs and tightening the nuts. A service bay also has to get the old wheel off first.

ABB's Dynamic Assembly Pack combines vision and force control so a robot can follow a car body that keeps moving and still fit parts precisely. A tire bay is easier in one way, since the car stands still, but open bay doors let in dust and weather. PitPro says it had to design around that.

PitPro's founder wants to move into other automated maintenance, and Automated Tire's SmartBay already adds wheel balancing and inspections. For small garages, a cobot like ABB's GoFa, which you teach by moving its arm by hand, could cover jobs too small for a full cell. I'd be happy if fewer mechanics had to wreck their backs every October.
