Both in the table and in the graph, the tires are Better Fuel Economy Factory Ratios Increased Power. vs 185/65-14 vs 185/70-14 vs 175/65-14 vs 185/65-15 vs 185/60-15. 175/65-R14 tires are 0.69 inches (17.5 mm) smaller in diameter than 175/70-R14 tires and the speedometer difference is 2.9%. Tire Size and Comparison Calculator calculate tire diameter from code and compare speedometer differences for tire sizes. The first number 195 is the tire width in millimeters. The 2nd number 55 is used to calculate the sidewall height or "aspect ratio", by percentage. So, the sidewall height of a 195/55 R 16 tire is 60% of 195 = 192. 165/65 r14 -2.9% 165/75 r14 +2.7% 175/60 r14 -3.6% 175/65 r14 -0.7% 175/70 r14 +2.4% 185/60 r14 -1.5% 185/65 r14 +1.5% 195/60 r14 +0.5% 195/65 r14 +3.7% 205/55 r14 -1 .
