…to calculating tread depth percentages because the tire is already legally worn out with just 2/32" of remaining tread depth." Useable tread depth is calculated by subtracting 2/32" from the tires' new tread depth. Then usable tread depth is compared to remaining tread depth in order to calculate…

…the tire manufacturer, revolutions per mile may be either measured in a laboratory or derived from calculations based on their previous test experience. Tire revolutions per mile cannot be calculated by simple math because the tire tread and sidewall bend and stretch (deflect) when the load of the…

…city and 30 mpg on the highway, installing tires with 20% greater rolling resistance would only drop fuel mileage by a calculated 3% (to 24.25 mpg) in the city and a calculated 5% (to 28.5 mpg) on the highway. While this is a measurable difference, it probably isn't much more of an influence on real…
