I'm getting falkins for my stang, and in deciding between the 215/45/16 and the 225/50/16 I came to a realization(which is related to ITRs)...

The total diameter of the 215 tire will be 23.61''.
The total diameter of the 225 tire will be 24.85''.

When you do the math, the difference in RPMs at any point is the same as if I droped the final gearing from 3:55 to 3:70.

I'm assuming the 215 tires will make the car accelerate faster just like the lower gears would?

 

yes

 

Your odometer will also be clocking more miles than your are actually traveling too.
So lets say you travel 100,000 miles with both tire combinations the smaller than stock, 23.61 inch diameter tire will calculate to a little more than 5,000 "extra" miles. Just some food for though - not necessarily all that important.

 

One other thing: you'll also have more wheel/fender gap.

 

Yes, but with the case of your stang, you may be undertired with the 215's, slowing you down.

 

so after driving a while...my car would be worth more due to less miles on the odometer if i was rollin on some 22's?

So maybe those people rolling on huge chrome wheels are smarter than we think they are...

 

haha, doubt it though

 

LOL

 

Does this same phenomena with the milage occur when you change out the final drive?

 

Nope. But, since our R's are a little off from the factory on the Speedo (show higher than actual speed), does that mean that we already log more miles than in reality?
