Lighter Wheels For Dyno
#1
would running lighter tires translate to slightly higher numbers on a dyno?
im asking because the weight difference on 2x285s are significant compared to 225 stockers.
would this through out the tuning of the car slightly?

Lower inertia wheels and tires would show a slightly higher power on an inertia dyno (Dynojet) or any dyno run where you accelerating, particularily if you are accelerating quickly. This does not mean you have made more power, it means you have wasted less power accelerating parts of the car.
Same but more so with a flywheel, this argument has come up before, some people claim a light flywheel produces more power. This is of course not possible, as a flywheel or wheels and tires can not increase the amount of fuel-air mixture going into your motor.
It shouldn't affect your tuning, the load versus RPM is all that matters there. If you have the higher inertia wheels on you might see more boost lower in RPM, but you are really, really splitting hairs there.
