Driving With Underinflated Tires
Driving With Underinflated Tires: The harsh winters of Central New Jersey can really do a number on heavy-duty vehicles and their tire pressure. In fact, the weather can be to blame for loss of tire inflation pressure (PSI) and decreased fuel mileage. Basic tire maintenance can help truckers avoid missing deadlines due to underinflated tires. Check out what you need to know about changing temperatures and tire PSI. Changes in air temperature can impact how fast air molecules can move within the tire, causing a fluctuation of PSI. So, if you’re a trucker starting out in Florida for a delivery in New England, you will likely notice a dramatic change in PSI by the time you get there. Hot tires not only affect pressure but also the sound of a tire. In fact, warm tires after a long drive can experience a 15 percent increase in inflation pressure compared with cold tires. As the driver, it’s impossible to know the exact pressure rating of your tires by sight. You must be on the lookout for common signs of under-inflation including: The TPMS light illuminates on the dashboard You get reduced steering and handling You have longer stopping distances You [...]
