275/45R21 Tires — Buying Guide for American Drivers
275/45R21 is a popular tire size for trucks, SUVs, and light-duty pickups in the USA. You may also see this size written as 275/45R21, 275 45 R21, 275-45-21, or 2754521 — all of those refer to the same tire. When shopping 275/45R21 tires, look for a load index that matches your vehicle's placard rating (typically 91–110 for passenger and light truck applications) and a speed rating of H or V for highway driving. All-season 275/45R21 tires are built for spring, summer, and fall driving when average temperatures stay above 7 °C — they harden in real American winter cold, so they're not a substitute for proper winter rubber. For sub-zero temperatures, snow, and ice you want a dedicated winter tire in 275/45R21 with the Three-Peak Mountain Snowflake (3PMSF) symbol, which is also a legal requirement in Quebec from December 1 to March 15. All-weather 275/45R21 tires split the difference — 3PMSF-certified for winter use but designed to run year-round without a seasonal swap, which is the right call for milder American climates. Filter by season, brand, speed rating, and load index above to find the right 275/45R21 tire for your vehicle. Autrex ships across the USA with free shipping on orders over $99.
275/45R21 reads as a 275 mm tread width, a sidewall 45% as tall as that width, on a 21-inch rim.
