This time of year, we tend to see extreme temperature drops. In fact, weather experts confirm another polar vortex is set to return this week with arctic blasts expected to hit everyone east of the Rockies. While we can bundle up with extra layers, our cars are left to fight the elements. Cold temperatures can immediately impact your tire pressure. Keep an eye for the symbol to the right – these are common alerts on your dashboard that help to keep you informed of your vehicle’s condition. If you see this indicator, you should take swift action to check and correct your tire’s air pressure.
The rule of thumb is for every 10° Fahrenheit change in air temperature, your tire’s inflation pressure will change by about 1 psi (up with higher temperatures and down with lower). In other words, if it were 40 degrees yesterday and -2 degrees today, you may experience a 4-5 psi loss in tire pressure. This may be enough to activate your low air pressure light.
Low air pressure should not be taken lightly
Not only is driving around with low tire pressure dangerous, it can damage your tires. It puts added stress on the sidewall which may cause them to wear quicker. Your goal should be to drive safely and to extend the life of your tires by maintaining proper tire pressure. You should also check the air pressure of your spare tire – so it’s ready if you need it. As always, if you have questions – please contact the nearest Dunn Tire store.
