Tire Pressure and Loading Limits 

Rollovers are more likely to occur on rural roads and highways—particularly undivided, two-way roads or divided roads with no barriers. When a vehicle goes off a rural road, the vehicle can overturn when it strikes a ditch or embankment, or is tripped by soft soil. Nearly 75% of all rollover crashes occur in rural areas, so practice caution when driving on rural roads.



Improperly inflated and worn tires can be especially dangerous because they inhibit your ability to maintain vehicle control, the most important factor in reducing the chance of rollover. Worn tires may cause the vehicle to slide sideways on wet or slippery pavement, sliding the vehicle off the road and increasing its risk of rolling over. Improper inflation can accelerate tire wear, and can even lead to tire failure. It is important to maintain your tires properly, and replace them when necessary.


Consult your vehicle's owner’s manual to determine the maximum safe load for your vehicle, as well as proper load distribution. If you’re using a roof rack, pay special attention to the manufacturer’s instructions and weight limits. Any load placed on the roof will be above the vehicle’s center of gravity, and will increase the vehicle’s likelihood of rolling over.
