EXPOSED
Nearly the whole job is physical: breaking beads, mounting and balancing tires, torquing lug nuts, patching punctures, and doing roadside service calls in weather and traffic. Language AI does not touch that work; the exposure is not automation but shop-level tooling (automated mount-and-balance machines, TPMS diagnostics that replace guesswork) and the low wages and low licensure that come with a procedure-driven role. This is a job that persists but does not command a premium.
Tasks largely resist digitisation. Breaking a rusted bead on a 20-year-old rim, wrestling a run-flat onto a low-profile wheel, and finding a slow leak by dunking the tire in the tank are tasks no software performs — the 16 rather than 19 reflects that mount-and-balance machines, TPMS relearn tools, and road-force balancers already carry the parts of the job that used to take feel and experience.
Hands-on in uncontrolled environments. You work bent over in a bay or kneeling on a highway shoulder with a torque wrench, handling 80-lb truck tires, hot brake components, and 120-psi inflation cages — the 18 is for uncontrolled roadside service in rain, snow, and live traffic, short of the 20 reserved for jobs with no fixed base at all.
No licence, no signature requirement. No state licenses tire changers; a shop may want TIA certification or a DOT medical card for service-truck driving, but a wheel that comes off at 70 mph becomes the shop's insurance claim and the manager's problem, not a personal license revocation, which is why this sits at 3 and not 8.
Some relationship component. Regulars ask for the guy who remembers their fleet and doesn't strip lug studs, and 24-hour roadside customers remember who showed up — but tires are bought on price and wait time, and most walk-ins never learn your name, so the relationship adds 7, not 13.
Executes defined procedures on defined inputs. Tread depth minimums, DOT date codes, patch-vs-plug rules, and manufacturer torque specs are written down and enforced; the discretion you do own — condemning a sidewall-damaged casing or refusing to remount a tire on a bent rim — is real but bounded, which is a 5 rather than a 2.
