Understanding Tire Sizes

When considering changing your tire size from 50 to 55, it's crucial to understand what these numbers mean. The numbers 50 and 55 in tire sizes refer to the aspect ratio, which is the height of the tire's sidewall as a percentage of its width. For example, in a tire size 225/50R17, the 50 means the tire's height is 50% of its 225mm width.

Implications of Changing to 55 Tires

Switching from 50 to 55 series tires will result in a taller tire. This change can have several effects on your vehicle:

  • Increased ground clearance
  • Altered speedometer readings
  • Changes in handling characteristics
  • Potential rubbing against wheel wells or suspension components

Considerations Before Changing Tire Size

Before making the switch, consider these factors:

  • Vehicle specifications and manufacturer recommendations
  • Clearance in wheel wells and around suspension components
  • Impact on vehicle performance and fuel efficiency
  • Legal requirements and regulations in your area

Proper Fitment and Installation

If you decide to change to 55 series tires, ensure proper fitment and installation:

  • Consult with a professional tire specialist
  • Use a tire size calculator to determine compatibility
  • Ensure the new tires have appropriate load and speed ratings
  • Consider adjusting your speedometer to account for the size change

Potential Benefits and Drawbacks

Benefits:

  • Improved ride comfort due to larger sidewalls
  • Better off-road capability in some cases
  • Potentially wider selection of tire options

Drawbacks:

  • Possible decrease in handling precision
  • Potential for rubbing or clearance issues
  • Inaccurate speedometer and odometer readings

Conclusion

While it is possible to put 55 tires instead of 50, it's not a decision to be made lightly. Always consult with a professional and consider all implications before making this change. Ensure that the new tire size is compatible with your vehicle and meets all safety standards.
