Tire Aspect Ratio
Often referred to as the profile or series, the aspect ratio of a tire is determined by dividing a tire's section height by its section width when the tire is: Inflated to maximum air pressure, Mounted on the approved measuring rim, & Under no load.
The lower aspect ratio responds to lateral force more effectively than a tire
with a higher aspect ratio.
The aspect ratio affects steering stability. Generally, the shorter the
sidewall, or the lower the aspect ratio, the less time it takes to transmit the
steering input from the wheel to the tread. The result is quicker steering
response.
Aspect ratio also affects the tread contact patch. As a rule, a low profile tire
produces a wider tread contact patch. This wider tread contact patch creates a
stiffer footprint that reduces distortion & provides improved cornering
traction. Aspect ratio also impacts ride. A low profile tire usually has a
stiffer ride than the standard aspect ratio of 75 or more.
