But they're just tires, how much of an impact could they really have on dyno numbers? In this video, we answer that question by showing how not only tires, but also tire pressure play a MUCH larger role than most realize.
Both pressure and size/stlye make a big difference. If you're planning on hitting the dyno and want the most consistent numbers possible use a street tire for the dyno session or, if you have to use radials, adjust the pressure on your drag radials accordingly. With that, we can't emphasize this enough. never exceed the tire's recommended pressure. A tire blowing out on the dyno will ruin everyone's day.
