Tires are crucial for vehicle performance; old tires can significantly impact fuel efficiency.

Q&A – How Can Old Tires Impact Fuel Efficiency?

• Q1: What are the signs of old tires?
  A1: Cracks, low tread depth, and bulges indicate old tires.
• Q2: How does tread depth affect fuel efficiency?
  A2: Shallow tread causes higher rolling resistance, leading to increased fuel consumption.
• Q3: Are there specific tire types more prone to fuel inefficiency?
  A3: Performance tires often have lower rolling resistance, whereas all-terrain tires can increase it.
• Q4: How often should tires be replaced?
  A4: Generally, tires should be replaced every 6 years, or when tread wear indicators show they’re worn out.
• Q5: Can tire pressure affect fuel efficiency?
  A5: Yes, under-inflated tires can increase rolling resistance.
• Q6: How much can old tires increase fuel consumption?
  A6: Studies suggest that worn tires can lead to a fuel efficiency decrease of 10-15%.
• Q7: Are there any long-term effects of using old tires?
  A7: They can lead to decreased vehicle safety, increased wear on other components, and higher fuel costs.
