The first hard freeze of the season is when TPMS warning lights start popping like flashbulbs at a NASCAR race. And for TRAVELLER owners, the pattern is predictable — a 20°F drop overnight, and suddenly the dash is lit up for all four corners. It’s not a fault, but it’s the most common service call from November through March.
The physics here is straightforward: tire pressure drops roughly 1 PSI for every 10°F decrease in ambient temperature. A tire set to 33 PSI in September can read 27 PSI by January. The sensor isn’t lying — it’s just doing its job. But the real issue for TRAVELLER vehicles, which share platforms with Chery and Jetour models, is how the aftermarket handles these seasonal swings.

The Summer Heat Problem
Winter gets the attention, but summer heat is the silent killer of TPMS sensors. Under-hood temperatures in a TRAVELLER parked in direct sun can push sensor internals past 185°F. That’s within spec for most modern units, but it accelerates battery drain — and a TPMS battery isn’t replaceable. The typical lifespan is 5-7 years, and extreme thermal cycling shaves time off that window.
The other summer issue is pressure-induced strain. When ambient temps hit 95°F and highway driving adds another 10 PSI from friction heat, a sensor mounted on a valve stem that’s seen three winters of road salt is at risk of cracking at the base. I’ve pulled more than a few corroded stems off TRAVELLER wheels that were original equipment from 2018.
What to Check During Seasonal Changeover
When a TRAVELLER comes in for a seasonal tire rotation, run through these three checks:
- Valve stem condition — Look for micro-cracks around the base. Any sign of rubber degradation means the sensor should be replaced, not just the stem.
- Battery voltage — If the vehicle is 2019 or older, test the sensor. A weak battery will give intermittent readings that feel like electrical gremlins.
- Sealing washer — The brass washer between the sensor and wheel gets work-hardened over time. It’s a $2 part that prevents a $40 reinstall when the sensor starts leaking.
The BL-ST-075 from BH-Sens covers all the TRAVELLER platform variants with a single pre-programmed unit. No cloning tool needed, no dealer-level programming. That’s the big win for independent shops — you stock one SKU and handle the full 41-application range across Chery, Cowin, Jetour, Karry, and Soueast.
Winter Storage Tips for Spare Sets
For customers running dedicated winter wheels, storage matters more than most realize. Sensors left in a garage that cycles between freezing and thawing will develop condensation inside the housing. Over two or three seasons, that moisture corrodes the circuit board contacts.
Advise customers to store spare wheels indoors, ideally in a climate-controlled space. If that’s not possible, pull the sensors and keep them in a sealed bag with a desiccant pack. It’s a five-minute job that doubles sensor life.
The Aftermarket Advantage
The OE sensor for this platform runs roughly 40% higher than the aftermarket equivalent, and the only real difference is the logo stamped on the housing. Baolong Technology is the OEM supplier for this fitment, so the BL-ST-075 is literally the same hardware — just packaged under the BH-Sens brand. For a shop owner, that means zero fitment surprises and no come-backs.
One note on pre-programmed units: always verify the sensor ID registers on the first attempt. The 433MHz frequency is stable across the range, but the TRAVELLER BCM can be finicky if the vehicle battery is low during programming. Pop a charger on before you start.
Bottom line: The BL-ST-075 is the right call for TRAVELLER TPMS work, winter or summer. Stock it, trust it, and move on to the next bay.
