  1. Iam using Honda WRV, it comes up with 195 60 R16, I want to upgrade please suggest which one is good for this car
    205 60 R16 or 215 55 R16

    1. Caitlin McCormack

      For improved grip, maintained comfort, and minimized changes to vehicle dynamics, the 205/60 R16 would likely be the better choice.

  2. I have a 2013 Acura MDX. The recommended tires size is 255/55/R18. Last summer I bought new tires in Michigan . I did not request any specific size but I assumed the appropriate tires would be mounted. I just took the car to my California mechanic to get ready to go back to Michigan. He informed me that the tires that were mounted are 225/55/R18. I was not informed that 225 tires were installed. Those tires now have 6K+ miles. According to your comparison as well as others I have seen the 225 tires are significantly smaller that the 255 with differences in wear, handling and ride. While your analysis references “benefits and drawbacks” between the two sizes, other sites say the smaller tires are dangerous for a vehicle the size of the MDX.

    My plan is to go back to the dealer and demand that they replace the tires with appropriate size tires. Since you now know the size of the vehicle that the tires are on I would be interested in getting your view about benefits and drawbacks. Am I right to be concerned about the tire size?

    1. Caitlin McCormack

      The difference in overall diameter between your original tire size (255/55/R18) and the tires currently mounted (225/55/R18) is approximately 4.7%. This variance exceeds the generally recommended maximum discrepancy of 3% in tire size alterations.

      It’s advisable to consider replacing your tires with ones that match the original specifications as soon as feasible. Using tires of an incorrect size can lead to several drawbacks, including diminished grip and handling capabilities.

      This can adversely affect your vehicle’s performance, particularly under challenging weather conditions. Ensuring that your tires conform to the manufacturer’s recommendations is crucial for maintaining optimal safety and performance.
