UK Weather & Tyre Pressure Tips
🌧️ Wet Conditions
For wet UK roads, consider running 0.1-0.2 Bar (2-3 PSI) lower than normal. This increases the contact patch for better grip on slippery surfaces. Don't go below the minimum tyre rating.
❄️ Winter Riding
Cold temperatures reduce tyre pressure. Check your tyres weekly in winter and add 0.1-0.2 Bar to compensate. A tyre inflated to 2.5 Bar in a warm garage may drop to 2.3 Bar outside in cold weather.
🚴 Commuting
For UK urban commuting with potholes and kerbs, run slightly lower pressure for puncture protection. The extra cushion helps absorb impacts. Run 0.1-0.2 Bar below the "firm" recommendation.
📏 Checking Pressure
Use a quality floor pump with a Bar/PSI gauge. Check pressure weekly, or before any ride longer than 30 minutes. Digital gauges are more accurate than dial gauges for precise readings.
