Teslita
The headline feature: slow leaks caught before the TPMS warning
5 featuresThe TPMS light in a Tesla is a late warning. By the time the yellow exclamation mark comes on, you're already about 25 % below the recommended pressure — a slow puncture has been quietly bleeding the tire for days, sometimes weeks. Teslita runs a sliding 14-day linear-slope analysis on every wheel: it watches the rate of pressure loss against the other three, against the season, and against your own historical baseline. If one wheel starts trending down faster than its neighbours, you get a heads-up at the dashboard — usually before you'd notice it from the wheel, and well before the car would.
14-day sliding slope per wheel Leak watch
Every wheel's pressure is plotted on a 14-day window and fitted to a linear slope. A normal tire loses about 0.01 bar per day to natural permeation; anything noticeably steeper, on one wheel and not the others, is the signature of a slow puncture. The window slides daily, so a fresh leak shows up within two or three days of its start.
Pre-TPMS warning by ~25 % pressure
Tesla's built-in TPMS sensor doesn't alert until the pressure drops roughly 25 % below the placard value — that's already a dangerous underinflation, with measurable handling and range loss. Teslita's slope detection picks up a slow leak while the wheel is still inside the green band, so you can get it patched before it ever becomes a hazard.
Cross-checks against the other three wheels
A cold snap drops all four pressures together. A leak only drops one. Teslita compares each wheel's slope against the other three on the same car, and only flags as "suspected leak" the wheel that's actually diverging — weather changes are picked up by every sensor, so they're filtered out automatically.
Nail-in-tire confirmation in hindsight
After you fix a puncture, scroll back and you'll see exactly when the leak started: a clean inflection point in the wheel's line. Useful for warranty claims (timestamped evidence the slow leak preceded your service visit) and just for confirming the repair shop actually found the right culprit.
Quiet by default, loud when it matters
Teslita doesn't buzz your phone every time the temperature drops a degree. The slow-leak flag only lights up when the slope is clearly steeper than the other three wheels and steeper than your seasonal baseline. False positives are rare, and you can tune the threshold from Settings if you live somewhere with extreme daily temperature swings.
Live per-wheel pressure on a top-down car view
4 featuresTesla-style top-down silhouette Live
A clean top-down silhouette of your car — Model 3, Model Y, Model S or Model X, matched automatically from your VIN — with the current pressure at each wheel overlaid on the corresponding corner. The same visual language Tesla uses in the car, but on a single page in your browser, with history attached.
Colour-coded against the placard spec
Each reading is colour-coded against the 2.9 bar (42 PSI) Tesla spec for most current models — green within 0.3 bar, amber within 0.5, red beyond. Out-of-spec wheels jump out at a glance; you don't have to remember the target or do mental arithmetic in a gas-station forecourt.
Updated whenever the car wakes
Pressures refresh every time the car comes online — typically when you unlock it, when it starts charging, or during a Sentry-mode wake. You don't need to drive the car to get a fresh reading; opening the door is enough for a new sample to land in your history.
Works for every Tesla on your account
Two cars in the household, a small fleet, or a single Model 3 — every vehicle on your Tesla account gets its own independent tire-pressure card and its own leak watch. Switch between them from the header; nothing crosses over.
90-day pressure trend, weather separated from leaks
4 featuresOne line per wheel, three months back
A single chart with four lines — one per wheel — covering the last 90 days. You can see the slow downward drift that comes with winter, the bump back up in spring, the inevitable air-pump top-up in October. Patterns are obvious; outliers are obvious.
Cold-weather drops are normal
A rule of thumb: tire pressure drops about 0.07 bar (1 PSI) for every 5 °C the air cools. A 20 °C cold snap takes 0.28 bar off every wheel — almost 10 % — and that's entirely normal physics, not a leak. Teslita charts the temperature curve next to the pressure curve so the correlation is visible.
Top-ups show as instant steps
Stop at a gas station with an air pump, top up to 2.9 bar, and the line jumps cleanly upward at that timestamp. Useful for remembering when you last bothered, and for cross-checking that the slow drift you're seeing now started after the last top-up.
Cross-tire comparison view
A second view stacks all four wheels on the same axis, so you can spot the one that's diverging from the pack. Front pair vs rear pair, left vs right, single odd-one-out — they're all visible at a glance.
Cold weather, expected pressure, and "is this normal?"
4 featuresExpected-vs-actual pressure for today
Given today's ambient temperature and your placard spec, Teslita shows what your tires should be reading right now. If actual matches expected, you're fine — even at 2.6 bar in winter. If actual is below expected, something else is going on.
Cold tire spec vs warm tire spec
The placard spec is for cold tires, measured before driving. Pressures rise about 0.07 bar per 5 °C as the tire heats up — a tire pumped to 2.9 bar cold can easily read 3.1 bar warm. Teslita tracks both, so a high reading after a motorway run doesn't fool you into bleeding air you'll regret in the morning.
Altitude and weather correction
Driving from Munich up to a 2 000 m Alpine pass changes the ambient pressure by about 0.2 bar, and the tire reading moves with it. The charts call out altitude excursions so the obvious dip you see climbing the pass isn't mistaken for a leak.
First-winter learning
The seasonal baseline gets sharper the longer you've been on Teslita. After one full winter, the slow-leak detector knows your specific car, your specific climate and your specific top-up cadence — and the false-positive rate drops toward zero.
Bar, PSI, kPa — whichever makes sense to you
3 featuresSeeded from your car's own GUI setting
On first connect, Teslita reads which unit your car is set to in its own infotainment screen — bar for most of Europe, PSI for North America and the UK. The dashboard, the trend chart and the alert thresholds all start out matching what the car shows. No manual configuration, no mismatch when you're cross-checking.
Switch anytime in Settings
Bar, PSI and kPa are all available from a single dropdown in Settings. The change is instant across every chart, every alert and every history view — no recompute, no re-import, no separate setting per car if you have several.
Round numbers that match the placard
Tesla's placard spec is shown in the unit your car is configured for — "42 PSI" in the US, "2,9 bar" in Germany. Teslita matches the same rounding so what you read here lines up with what the door-jamb sticker reads. No "42.03 PSI" pedantry on a sticker that says 42.
Alerts, history, and the boring trust bits
4 featuresOne alert per leak, not one per cold morning
When the slow-leak detector fires, you get one notification per wheel per event — not a fresh alert every time the pressure changes. The alert names the wheel ("front left"), the slope ("losing 0.05 bar/day"), and the suspected start date. Open the chart from the notification and you see the inflection point directly.
Full pressure history, kept forever
Every sample your car has ever sent us is kept — not just the last 90 days. Scroll the chart back through last winter, the winter before that, the summer you bought the car. The slow-leak detection only uses the recent window, but the archive lets you spot tire-life patterns across years.
Official Fleet Telemetry, never your password
Teslita reads tire pressures over the official Tesla Fleet Telemetry connection, which you authorise via Tesla's own OAuth screen. Your Tesla password never touches Teslita. Revoke the connection from your Tesla account at any time — readings already captured stay in your history.
Delete everything in one click
Want out? A single confirmation in Settings wipes your Teslita account and every pressure sample from our servers, and revokes the OAuth token so Teslita disappears from your Tesla account too. No retention period, no email chain to start.

Two minutes from signup to "my dashboard already knows my tires."
Connect your Tesla account
Sign up with email, click "Connect Tesla", approve the Fleet Telemetry scopes on Tesla's own login screen. No app to install, no extra app on the car — the whole setup runs in the browser.
Drive normally for a week or two
Teslita pulls in your existing pressure history if your car has streamed any to Tesla, and starts sampling fresh values every time the car wakes. After about a week, the 14-day sliding window has enough data to detect a slow leak with high confidence.
Get a heads-up before the TPMS does
If a wheel starts losing air faster than the others, Teslita flags it on the dashboard and (if you opt in) sends a notification. Pop the tire off at your usual workshop, find the nail, get it patched — long before the warning light would have come on.
Why people pick Teslita for tire pressure
Tesla's built-in TPMS is a hazard alarm, not a maintenance tool. Most Tesla apps just mirror the same single number from the car, with no trend, no per-wheel history and no leak detection.
