205/45/17 or 205/40/17 Front & 215/40/17 Rear

So 300% is an acceptable estimate, yet 400% is quite an exaggeration?

Hmmm... you have an interesting command of mathematics.

Anyway, tire rotation doesn't necessarily extend overall tirelife; if done regularly, it simply allows for even tire wear back to front.

Percentages are represented by their decimal equivalent. 300% = 3.00, 400% = 4.00 and so on... 25 x 3.00= 75, 25 X 4.00 = 100 and so on... Basic math!

Now, here's where is get even more fun, I'll teach you a little about rubber and tires. Every time a tire is heated up and cooled down, it goes through a heat cycle. Race tires lose a good amount of grip every time they are cycled. Even if they still have a lot of meat left, they can be slicker than snot if they have been repeatedly cycled.

The same goes for street tires, if you want to maintain the maximum amount of traction at the lowest cost. Rotate your tires, if you want to have nice new tires on the front and old hard as rock tires in the rear... You get the picture.

There is also proper/even wear, and keeping a consistent contact patch.. Who cares about any of that silly stuff?
