Why Winter Tire Swaps Demand TPMS Attention
Fengon vehicles—including popular models like the Fengon 580, 560, and ix5—come equipped with direct TPMS sensors that transmit real-time pressure and temperature data to your dashboard. When you swap to winter rims or tires, you have three options:
- Reuse the existing sensors in the winter wheels (requires transferring them).
- Install a second set of sensors in the winter wheels (pre-programmed to match your vehicle).
- Ignore the TPMS warning light (not recommended—it affects safety and may fail annual inspections).
The BL-ST-057 BH-Sens sensor is a direct-fit solution for Fengon and several Chinese-brand vehicles, operating at 433MHz with OE numbers 3601010CD01, 3601010DG01, and 3601010MK02. It’s clamp-in and pre-programmed, meaning no additional programming tool is needed for most Fengon models.
Temperature-Driven Pressure Changes: What to Expect
Rubber is not perfectly airtight, but the larger factor in winter pressure loss is physics: for every 10°F drop in ambient temperature, tire pressure decreases by about 1 psi (0.07 bar). In many regions, winter can bring a 30–40°F swing from autumn setup temperatures, meaning your tires could be 3–4 psi low before you even drive.
Pressure Adjustment Table
| Condition | Recommended Action |
|---|---|
| Temperature drop >20°F since last inflation | Add 2–3 psi above the door-sticker pressure |
| TPMS warning light on during first cold morning | Check pressure when tires are cold (not after driving) |
| Using winter tires with different load ratings | Follow the winter tire manufacturer’s pressure recommendation, not the summer tire spec |
| After a week of sub-zero temps | Recheck all four tires—cold air can trigger false low-pressure warnings |
Pro tip: Set your cold tire pressure 2–3 psi higher than the manufacturer’s recommendation when you know a cold snap is coming. This compensates for the drop without over-inflating during milder days.
Storage Tips for TPMS Sensors During Off-Season
If you’re removing sensors from summer wheels and storing them for next season, follow these steps to avoid corrosion, battery drain, or physical damage:
- Store sensors in a climate-controlled area (avoid garages with extreme temperature swings or high humidity). Ideal range: 40–80°F.
- Keep sensors in a sealed plastic bag with a silica gel packet to absorb moisture. The rubber valve stem and metal housing can corrode if exposed to condensation.
- Label the sensor positions (LF, RF, LR, RR) so you know which wheel they came from. Some Fengon models require sensor position learning after reinstallation.
- Do not stack heavy items on top of stored sensors—the valve stem can bend or crack.
- Battery life average is 5–7 years from the manufacture date. If your sensors are over 4 years old, consider replacing them during the winter swap to avoid a failed sensor mid-season.
Recommended Part
For Fengon owners who need a reliable, pre-programmed 433MHz sensor that fits multiple Chinese-brand vehicles, the BL-ST-057 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Avatr, Changan, Deepal, Mazda, Nevo & 1 More | OE# 3601010CD01, 3601010DG01, 3601010MK02 is a smart choice. It’s clamp-in, matches OE frequencies for Fengon models, and eliminates the need for a TPMS programming tool. Keep one set in your winter wheels and another in your summer set for hassle-free seasonal swaps.
FAQ
How do I know if my Fengon uses 433MHz TPMS sensors?
Most Fengon models produced after 2015 use 433MHz sensors. Check your owner’s manual or look at the OE part number on your current sensor—if it matches 3601010CD01, 3601010DG01, or 3601010MK02, the BL-ST-057 is a direct replacement. When in doubt, call your local dealer with your VIN.
Can I install winter tires without TPMS sensors?
Technically yes, but your dashboard warning light will stay on, and in many regions, a illuminated TPMS light can cause a failed safety inspection. Additionally, you lose real-time pressure monitoring—critical in winter when pressure drops can happen quickly.
Do I need to reprogram the sensors after swapping wheels?
If you’re using pre-programmed sensors like the BL-ST-057, the vehicle should recognize them automatically after a short drive (usually 5–10 minutes at speeds above 15 mph). Some Fengon models require a relearn procedure using a TPMS tool or the vehicle’s menu—consult your owner’s manual for the specific method.
What’s the best way to transport sensors during a wheel swap?
Remove the sensor from the wheel by unscrewing the valve stem nut. Place each sensor in a padded envelope or small box with bubble wrap. Never carry them loose in a toolbox where they can rattle against metal tools. The internal electronics and battery are sensitive to shock.
