About the role
Mobile Tyre Fitter — Sheffield and South Yorkshire. Self-employed profit-share role, not a wage. You keep 30% of every job KJ Tyres routes to you. We take the customer booking, confirm the tyre size and price, and drop you a routed run of jobs each day. You'll cover mobile fit and balance at the customer's home or workplace, TPMS resets, puncture repairs, run-flat swaps, and fleet call-outs for KJ partner accounts. Most jobs are 25–45 minutes on site; fleet visits can be a batch of 4–8 wheels in one stop. Jobs are dispatched via the KJ portal with the vehicle, tyre spec, address and slot confirmed. Tickets range from £25 for a puncture repair up to £600+ for a full set of premium tyres. Suits an experienced mobile tyre fitter with own mobile fitting rig (machine, balancer, generator/inverter). Not for someone without their own kit — the rig is essential.
Responsibilities
- Fit and balance car and light-van tyres on-site at customer / fleet locations
- Repair punctures to BS AU 159 where safe and appropriate
- Reset TPMS sensors and replace failed valves
- Fit and remove run-flats correctly
- Handle fleet batch call-outs efficiently
- Photo-document each job (tread depth, before/after) in the KJ portal
- Cash / card handling for any customer top-ups per the KJ payment process
Requirements
- Own mobile tyre-fitting rig (machine, balancer, generator or vehicle inverter)
- Own suitable van
- Full UK driving licence and right to work in the UK
- Public liability insurance
- Smartphone for the KJ portal
- Time-served mobile fitting experience

Do the work, get paid your share

Why KJ, not a company job
A plumber does 3–4 jobs a day; a surveyor 2–4; a solicitor a handful of matters. The client pays hundreds — often thousands. You take home a fraction. The company keeps the rest.
