Dunlop Winter Maxx 225/45R18

225 is the tread width in millimeters, 45 means the sidewall is 45% of that width, and R18 is the 18-inch rim it mounts on. 95 is the load index (1,521 lbs per tire), and T is the speed rating (up to 118 mph).

The Winter Maxx is a dedicated winter tire, not an all-season. It's engineered specifically for cold temperatures, snow, and ice, and carries the Three-Peak Mountain Snowflake certification that all-season tires typically do not. For best results, it should be swapped out for a warm-weather or all-season tire once temperatures consistently rise above freezing.

The Three-Peak Mountain Snowflake (3PMSF) symbol indicates the tire has passed a standardized traction test in severe snow conditions. It's a meaningful distinction — it means the Winter Maxx has been independently verified to perform beyond the minimum threshold required of all-season tires in winter environments.

The cold-weather compound and asymmetrical tread are designed to provide grip on both icy and snow-covered roads. That said, no winter tire eliminates the risks of black ice or extremely hard-packed ice entirely — driving speed and conditions always matter. The Winter Maxx is a strong choice for typical winter driving but is not a substitute for cautious driving on severe ice.

The Winter Maxx is built for passenger cars and is available in sizes fitting 15- to 18-inch wheels. It is not designed for light trucks or SUVs — Dunlop offers separate tire lines for those vehicle types.
