…is the tire's aspect ratio or profile. This percentage represents the ratio of the sidewall's section height to the tire's section width. The section height can be calculated by multiplying the section width by the aspect ratio percentage. The answer will be the height of one sidewall. For example:…
…increases and the sidewall height decreases. The contact patch of the tire changes shape by becoming shorter and wider. While the shape changes, the size (area) of the contact patch remains relatively unchanged. * High aspect ratio = tall and narrow contact patch* Short aspect ratio = chort and wide…
…the size of a 4” x 6” printed picture. The shape of a tire’s contact patch is also dependent on the tire’s profile (aspect ratio). Most passenger car and light truck tires feature higher profile tire sizes that typically have longer and narrower contact patches; while most…
…Width" (cross section) in millimeters. Sidewall Aspect Ratio Following the three digits identifying the tire's Section Width in millimeters is a two-digit number that identifies the tire's profile or aspect ratio. This is the “height” of the sidewall, expressed as a percentage of the…
…"Series" of the tire is the second part of the tire's size. For example, a 205/65R15 is a 65 Series tire. More information on sidewall aspect ratio can be found by reading "Tire Size Guide." * 60 Series and up $12.00 * 50-55 Series $12.00 * 40-45 Series $15.00 * 35 Series and…
…suggest an affordable wheel and tire package for winter, downsizing the wheel and tire whenever possible. By downsizing, you get a higher sidewall aspect ratio along with a narrower tread width that helps the tire cut the snow. But what do you do about your tire pressure monitoring systems (TPMS)?…
…increases and the sidewall height decreases. The contact patch of the tire changes shape by becoming shorter and wider. While the shape changes, the size (area) of the contact patch remains relatively unchanged. * High aspect ratio = tall and narrow contact patch * Short aspect ratio = short and…
…decreasing the aspect ratio (second number in the size). The wheel size stays the same so you will not have to purchase new wheels. Plus 1 - Increase the section width while decreasing aspect ratio but also increase the wheel size by 1 inch. The result is approximately 1/2" less sidewall on the…
…often a function of the tire size, internal structure, load, ambient temperature and time spent stationary. Low aspect ratio tires have less sidewall flex due to their short sidewalls and much of their load carrying capacity is absorbed by the deflection of their wide footprints. The tread compounds…
…branded on a tire's sidewall identifies how much load the tire is designed to carry at its industry specified pressure." Passenger Tires Since most P-metric passenger tires are manufactured in the standard load range, they will have nothing branded on their sidewalls or may be branded standard…
