Smallest Tire Size
The smallest tire size you might consider for the 2018 Mazda 3 Grand Touring is 205/55R16. While this size is typically associated with the Sport trim, some owners opt for it if they want a more comfortable ride with a softer sidewall. Here are some considerations:

- Performance: The wider contact patch improves traction, which can be crucial in wet or slippery conditions.
