Built for 4x4 and off-road use, the TP-S15i is one of the few tyre pressure monitoring systems that will alarm at pressures as low as 0.9 Bar — so airing down for sand, rock or bush tracks won't leave you fighting a nuisance alarm.

The kit ships with a solar-powered colour display and four internal sensors, showing live pressure for all four tyres in BAR. Alongside pressure, the system tracks tyre temperature and warns the driver of slow leaks, punctures and overheating above 80°C. Alarm thresholds are driver-adjustable, and the working range of 0.9–6.0 Bar covers everything from light passenger cars through to loaded 4x4s and campers.

Every sensor arrives pre-paired and labelled for its wheel position, so installation is a fit-and-go job.

Pairing Sensors to the Display

Please note: every TPMS kit and package we sell is supplied pre-programmed — no setup is needed out of the box. Re-pairing is only required with internal sensors after a tyre rotation, when sensor positions change. Two options:

Option 1 — manual

Fit the sensors, put the display into programming mode (refer to the manual), then inflate or deflate each tyre slightly as instructed. The sensor detects the pressure change and transmits to the display, where the data is saved.

Option 2 — sensor partner tool

An internal sensor partner (available on our website) triggers the sensors to transmit on demand, so there's no need to adjust tyre pressures at all. Fit the sensors, put the display into programming mode, activate each sensor with the tool, and save.

Step-by-step pairing procedure

  1. Press the spanner button five times in quick succession — a beep confirms you're in pairing mode.
  2. The front-left tyre position will begin flashing.
  3. Take the display to the flashing tyre position and release a small amount of air from that tyre.
  4. A pressure reading appears on the display after roughly 4–8 seconds.
  5. Press the spanner button once — the flashing stops, confirming the sensor is registered.
  6. Use the arrow button to move to the next tyre and repeat steps 3–5.
  7. With all four tyres done, hold the spanner button for 4 seconds to save and exit pairing mode.
