Smallest Tire Size Options
If you’re looking to downsize your tires for any reason, such as improving ride comfort or reducing costs, there are a few smaller tire sizes that some owners have successfully used. However, keep in mind that going smaller can affect handling and performance.

- 255/35R18: This size provides a wider contact patch, enhancing grip during acceleration and cornering. Many owners praise this size for its performance improvements.
- 265/30R19: For those looking to go even bigger, this size offers excellent handling characteristics. It can be a tight fit, so ensure there’s enough clearance in the wheel wells.
While larger tires can improve performance, they can also lead to a harsher ride and increased road noise. It’s essential to weigh the pros and cons before making a decision.
