Check your car's owner's manual or the sticker on the driver's side doorjamb for the correct tire pressure. You should also inspect your tires for wear and tear, such as cuts, bulges, or uneven wear. If you notice any of these issues, it's time to replace your tires. Having your car aligned is also important, as it ensures that your tires are pointing in the correct direction. Misalignment can cause uneven tire wear, reduced fuel efficiency, and poor handling. It can also affect the car's steering. Have your car aligned regularly, especially if you notice any changes in handling or if you've hit a pothole or curb. By taking care of your tires, you can extend their lifespan and improve your car's performance. Maintaining your tires is easy and beneficial.
