When winter arrives in Colorado, the temperature isn’t the only thing that drops – your tire pressure does too! As the mercury falls, the air inside your tires contracts, causing a decrease in pressure. This can lead to reduced fuel efficiency, uneven tire wear, and even safety risks. Let’s dive into why tire pressure matters and how to keep your tires road-ready this winter.
Why Does Tire Pressure Drop in Cold Weather?
For every 10-degree Fahrenheit drop in temperature, your tires can lose about 1-2 psi (pounds per square inch). For example, a tire properly inflated at 35 psi when it’s 70°F may drop to around 30-31 psi at 20°F. Since Colorado winters often bring significant temperature swings, this change can catch drivers off guard.
Low tire pressure impacts more than just your ride comfort. It increases rolling resistance, which means your car has to work harder, lowering fuel efficiency. It also leads to uneven tire wear, shortening your tires’ lifespan, and may reduce traction—especially on icy or snowy roads common in Boulder and the Rockies.
How to Check and Maintain Tire Pressure in Winter
- Check Regularly: Make it a habit to check your tire pressure at least once a month during the winter. Most gas stations have air pumps, or you can invest in a portable tire pressure gauge for convenience.
- Know Your Vehicle’s Recommendation: Check your owner’s manual or the sticker inside your driver’s side door for the recommended tire pressure. Don’t rely on the number printed on the tire itself—that’s the maximum pressure, not the ideal level for your vehicle.
- Adjust for Elevation: Boulder and other Colorado mountain towns are at high altitudes, which can already affect tire pressure. Ensure your tires are correctly inflated before heading up into higher elevations, especially when driving to ski resorts like Eldora or along I-70.
- Don’t Forget the Spare: Cold weather affects your spare tire too. Check its pressure to avoid surprises if you need to use it.
