Specifically, are your tires at the correct pressure? With the changing weather the Washington DC area has experienced, it’s quite possible the pressure in your tires may have changed by as much as 6 PSI. A good rule of thumb is for every 10 degrees the pressure inside your tires can change by 1-2 PSI. So a change of twenty degrees could affect tire pressure by 2-4 PSI.
During this time of year the biggest change happens at night when temperatures drop more potentially leaving your tire pressure much lower before you head off to work. I normally check the pressure in my tires every 2-3 weeks when temperatures are consistent, and 1-2 weeks when the temperatures begin to drop. Remember, the tires are the only four contact patches that touch the road!
When you check the pressure it’s the perfect time to give the tires a quick once over to see whether any bubbles may have formed on the sidewalls or some other issue is developing. It’s also good to check the wheels. Last winter when I was checking the pressure I discovered one of the spokes in my wheels had a crack through the entire width potentially creating a risk for me driving.
