Winter Tyre Pressure Guide: Cold Weather Tips
As temperatures drop, so does your tyre pressure. Here's everything you need to know to stay safe and maintain traction on slippery winter roads.
The 10°F Rule
For every 10°F (5.5°C) drop in temperature, your tyre pressure decreases by approximately 1 PSI. In the UK, where temperatures can swing significantly, this can leave your tyres dangerously under-inflated without you realizing.
Winter Maintenance Tips
1. Check More Frequently
In summer, monthly checks are fine. In winter, we recommend checking every two weeks or whenever there is a significant drop in temperature.
2. Don't Ignore the TPMS Light
It's common for the TPMS light to come on in the morning when it's coldest. Do not ignore this. It means your pressure has dropped below the safe threshold. Inflate your tyres to the correct level immediately.
3. Winter Tyres Need Pressure Too
If you switch to winter tyres, they still need to be maintained at the correct pressure. Check your owner's manual - sometimes winter tyres require slightly different pressures (often +3-5 PSI) to compensate for the cold.
Winter FAQ
Should I lower tyre pressure for snow?
No. This is a myth. Lowering pressure closes up the tread pattern, making it less effective at gripping snow. Always maintain the manufacturer's recommended pressure for the best traction.
Why does my tyre pressure light come on in the morning?
Air contracts when cold, lowering the pressure. If your tyres were borderline low, the overnight temperature drop can push them below the warning threshold.
