Knowing When To Replace

It’s essential to know when to replace your tires to ensure your safety on the road. Here are a few key indicators that your tires may need to be replaced:
  • Tread Wear: Inspect your tire tread regularly by performing the penny test. Place a penny upside down in the tread groove. If the top of Lincoln’s head is visible, your tread is worn, and it’s time for new tires.
  • Tire Age: Tires age over time, even if they haven’t been used frequently. Most manufacturers recommend replacing tires after six years, regardless of their tread depth. You can find the manufacturing date on the sidewall, indicating the week and year the tire was made.
  • Cracks or Bulges: Examine your tires for any cracks, cuts, or bulges on the sidewalls or tread surface. These signs indicate potential tire failure, and should be addressed immediately.
  • Performance Issues: If you notice vibration, poor handling, or increased braking distance, it could be a sign of tire wear or damage. Have a professional inspect your tires to determine if replacement is necessary.

Choosing The Right Replacement Tires

When it comes to choosing replacement tires, it’s vital to consider your driving needs and the climate you typically encounter. Here are a few factors to keep in mind to ensure you select the right replacement tires:
  • Tire Size: Refer to your vehicle’s owner’s manual or the sidewall of the current tires to find the right tire size. Choose a size that matches the recommendations for your vehicle.
  • Tire Type: Consider the type of driving you do. If you often encounter snowy or icy conditions, winter tires may be necessary. For all-season performance, all-season tires are a suitable option.
  • Tire Brands: Research reputable tire brands known for their quality and durability. Reading customer reviews and seeking recommendations from professionals can help you find reliable options.
  • Budget: Determine your budget for tire replacement. While it’s important to prioritize safety, you can find options that suit your price range.
Remember, when replacing your tires, it’s always recommended to consult with a professional to ensure you make the best choice based on your specific needs and the recommendations for your vehicle.
