Smallest Tire Size Options
While the stock tire size for the GXP is 225/50R18, some enthusiasts have explored smaller options for various reasons, including improved acceleration and handling. However, going smaller can compromise ride comfort and traction. Here are the smallest tire sizes you might consider:

Larger tires can help with grip and handling, but they may also affect fuel economy and ride quality. Always check for compatibility with your vehicle’s suspension and wheel wells.
