Check tire pressure
One of the simplest and most beneficial things you can do to preserve the life of your tires is to periodically check them. Typically a once-a-month walk around your car is all you will need to visually inspect y
Low pressure causes the tire sidewall to flex more, thereby building up more heat and wearing down the tire much faster.
Excessively high pressure causes the middle of the tread to bulge out more, therefore wearing down the center of the tire significantly faster, causing uneven wear.
You should look for a bulge near the ground on the tire which would indicate that the air pressure is low and if you notice one tire that seems to be a little low, make sure to inflate it back to the appropriate amount and if you notice that one of the tires loses pressure much faster than the others, it is recommended you inspect it for nails, screws, glass, or other objects that may have become embedded into the tire.
Excessively high pressure
Tires should never be filled up the maximum rating that is stamped on the side of the tire. This is the very maximum threshold which the tire was designed to withstand, and not the recommended operating amount. Tires which are inflated above the recommended amount wear out unevenly and produce a very stiff ride.
Overinflating a tire beyond its maximum rating can cause serious injury or death.
The recommended PSI for your vehicle can be found:
1. On a sticker on the door jamb on the driver’s side
2. On a sticker on the lid of your trunk
3. In your owner’s manual
If you are unable to find the exact recommended PSI, then an acceptable pressure for most passenger cars, minivans, and SUVs and light trucks is generally 32-35 PSI.
For ¾ ton and 1 ton trucks and vans, the general recommended air pressure is typically 35-40 PSI in the front tires and 45-50 PSI in the rear whereas a PSI of 70-75 in the front and rear is generally recommended for heavy trucks carrying maximum load.
Make sure to double check what the maximum PSI rating on the tires is before inflating. Overinflating a tire beyond its maximum rating can cause serious injury or death.
Cars and trucks alike often specify differing air pressure front to rear. Why? There are two main reasons for this, load and handling.
Load: Whether you have a commuter car or a 1-ton truck, its primary function is to carry people and items. Secondly, many vehicles specify more air in the back to allow for more weight to be carried.
Handling: Even if you don’t carry heavy loads, lowering the PSI in the back tires may affect how your vehicle handles. You may notice your rear end lose traction and slide out a little when taking a corner if the PSI is too low.
