215/40R18 Tires — Buying Guide for American Drivers
215/40R18 is a popular tire size for cars, SUVs, and crossovers in the USA. You may also see this size written as 215/40R18, 215 40 R18, 215-40-18, or 2154018 — all of those refer to the same tire. When shopping 215/40R18 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 215/40R18 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 215/40R18 with the Three-Peak Mountain Snowflake (3PMSF) symbol, which is also a legal requirement in Quebec from December 1 to March 15. All-weather 215/40R18 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 215/40R18 tire for your vehicle. Autrex ships across the USA with free shipping on orders over $99.
