True or False? Your driving habits and tire pressure can impact your gas mileage as much as 20% - True. In fact they can impact your gas mileage by up to 30%! Driving a vehicle with underinflated tires is like swimming with weights strapped to your legs. Underinflated tires can take anywhere from 4% to 10% of your vehicle's potential gas mileage.
TIP: The Rubber Manufacturers Association (RMA) recommends getting in the habit of taking five minutes every month to check your tires, including the spare.
Is your vehicle pulling to one side, or shaking?
A bad jolt from hitting a curb or pothole can throw your front end out of alignment and damage your tires. Have a tire dealer check the alignment periodically to ensure that your car is properly aligned.
Promotes uniform tire wear.
Regularly rotating your vehicle's tires will help you achieve more uniform wear. Unless your vehicle owner's manual has a specific recommendation, the guideline for tire rotation is approximately every 5,000 miles.
Measure it -- and inspect it.
Advanced and unusual wear can reduce the ability of tread to grip the road in adverse conditions. Visually check your tires for uneven wear, looking for high and low areas or unusually smooth areas. Also check for signs of damage.
Do you know what amount of your tire width is touching the ground while driving? Look at the palm of your hand - that's it. Four palm size pieces of rubber!
