We simulated that tire-change situation of a 26-inch versus a 28-inch tall tire using a taller 3.55:1 (versus a 4.10:1 gear) ratio, and the car lost barely 0.07-second running 10.30s at 130 mph ...

First, you want to figure out how fast the car will go in each gear. This is simple. At 0 rpm, the car will go 0 mph in any gear. You're now halfway there. Next, you'll want to know how fast it ...

Obviously, the car will look killer with a set of monster 33-inch-tall Mickey Thompson tires, but this swap to the much taller tires instantly transforms the final drive ratio from 3.08 to 2.42!
