Id say that would be Amount of Alcahole X number of girls cheering you on X length of road divided by the amount of time you hold your foot on the accelerator and squared by break release and skid time! in other words....I wouldnt have a clue but you provided me with 5 minutes of brain wandering during a boring morning in the office. regards Daniel.
You can divide the life of the tire by it's tread wear number to get a factor that you can use to estimate how long a tire with a different tread wear will last. Using the example we just gave, 20 divided by 240 gives 0.083. So, if you multiply another tread wear rate by this factor you can see that a tire with a Tread wear 100 would have an expected life of 8.3 months 00 x .083= 8.3 and if you considered a tire with Tread wear 300 you might expect that tire to last 24.9 months. 300 x .083 = 24.9
