About 255/45R20 Tires
The 255/45R20 tire size is commonly found on luxury sedans like the BMW 5 Series, Mercedes E-Class, Audi A6, Cadillac CT5, and performance crossovers such as the Porsche Macan and BMW X3. This size designation breaks down to 255mm tread width, 45% aspect ratio (sidewall height is 45% of the 255mm width, equaling 114.75mm), and fits 20-inch diameter wheels. Typical load indices for this size range from 101-105 (1,819-2,039 lbs per tire), with speed ratings commonly H (130 mph), V (149 mph), or W (168 mph) for performance applications.
The 255/45R20 size strikes a balance between performance handling and acceptable ride comfort, with the lower 45% sidewall providing responsive steering feedback while still offering reasonable cushioning over road imperfections. Expect to pay $200-350 for budget options, $350-500 for mid-range tires, and $500-800+ for premium performance models. This size has excellent availability in all-season variants, good selection in summer performance options, and limited but growing winter tire choices. Due to the larger wheel diameter and performance orientation, these tires require precise alignment, benefit from 5,000-7,500 mile rotation intervals, and show increased sensitivity to improper inflation pressure and aggressive driving habits.
