Golf Cart TPMS: Tyre Pressure Without a Display Golf cart TPMS for courses, resorts and utility fleets - why a phone-readable sensor beats a receiver and display, and the four limits to check before you buy.

Golf cart TPMS is a different purchase from a truck system

Golf cart TPMS is usually the first tyre-pressure decision a course manager has to make, and it rarely looks like the truck version of the same question. A haul truck has a controller, a network and a maintenance department. A golf course has a shed, a few dozen carts and one person who checks them before the first tee time.

That changes what "good" means. A cart system that needs a receiver, a display, a harness and a pairing procedure does not get used, because the value per cart is too small to justify the installation. A cart system that is a sensor and a phone gets used, because the check takes seconds and nothing has to be mounted.

Why low-pressure tyres fail quietly

Golf carts run at low pressures on tyres that are soft by design. A tyre at 8 psi that drops to 5 psi does not look flat — it looks normal, and the cart still drives. What it does instead is:

• run hotter, because the sidewall flexes more than it was designed to;
• wear unevenly, usually on the shoulder;
• lose range, which on an electric cart shows up as "the battery is going" rather than "the tyre is low";
• and eventually fail under load — on a slope, with passengers, at the far end of the course.

None of that is visible during a walk-around. The only way to catch it early is to measure it, and the only way anyone measures it is if measuring is faster than not measuring.

What a phone-readable sensor actually gives you

Property	What it means on a cart
2.4 GHz Bluetooth, no receiver	The phone is the reader. Nothing to mount, wire or power on the vehicle.
0–500 kPa gauge (0–600 kPa absolute), ±2 kPa	Cart pressures sit well inside this range; the accuracy is finer than the pressure change that matters.
Replaceable CR1632, about 1.5 years	A coin cell you can change in the shed. No re-pairing after the change, so it is a maintenance task, not a service visit.
IP67	Wash-down and rain. Not a submarine rating — a cart does not need one.
Ø21 mm × 16 mm, valve-mounted	Fits standard cart valves. Nothing to dismantle.
−40 to +85 °C working	Covers a shed in winter and a cart path in summer.

What it does not give you, and this is the honest part: no continuous monitoring and no in-cab alarm. There is no reader on the cart, so nothing is watching while the cart is out. A leak that develops during a round is seen at the next check, not at the moment it starts. For most courses that is the right trade — the check is the routine, and the routine is cheap. For a 24-hour operation, it is the wrong trade, and a receiver-based system is the answer.

The four limits to check before you buy

1. How often will anyone actually check? If the answer is "once a week", a sensor plus phone is

enough. If the answer is "nobody", buy nothing — the hardware will not fix a process.

1. Who holds the phone? One shared phone per shed works; a per-cart phone does not. Decide this

before choosing an app model.

1. Do carts get swapped between courses or borrowed? If so, the identity of the cart must live with

the cart, not with the phone. That is a configuration question, not a sensor question.

1. What is the actual working pressure, and does it drift seasonally? Set baselines per season rather

than one number for the year; a baseline that is wrong in July trains people to ignore alarms.

Where this fits in a fleet

For a resort with ten carts, this is a fifty-dollar-per-cart question and the answer is usually "yes, because a ruined tyre costs more than a handful of sensors". For a course with a hundred carts, it is also an inventory question: which carts were checked this morning, and which were not. That is where a phone-based record — even a shared spreadsheet — does more for tyre life than a more expensive sensor.

If the carts are part of a larger utility fleet (grounds buggies, maintenance carts, light electric utility vehicles), the same sensor works across them, and the same routine covers them.

If you build or distribute carts

We supply as OEM/ODM: our marking, your marking, packaging, app configuration. Tell us the cart class, the working pressure, and whether the app should be yours or ours, and we will answer with the configuration in writing.

For the same sensor applied to other vehicles, see three-wheeler TPMS or the golf cart application page. To discuss a programme, contact us with the cart count and the working pressure — that is enough for a useful first answer.
