Distance-weighted averages of drives Roamer logged on each tire, without a trailer, from owners who share their data with the fleet. A figure shows once 3 vehicles and about 100 miles stand behind it. A gap between two tires shows only when it's clear: bigger than the differences between vehicles on each tire would explain, at 95% confidence. Green marks a clear gain of 3% or more. Outside temperature is the average of a drive's start and end readings. Your results will vary with driving style, speed, weather and vehicle.
