Also, if you got a good constant slope hill, you could see your acceleration decrease as you picked up speed due to aero-forces.
If the point is to measure the MAX traction of tires at various inflation pressures, you have to be spinning the tires if you are accellerating, or have the brakes locked (or near locked) if you are braking, or cornering hard if you are doing lateral grip. Any of those will severely wear the tires. Any test that doesn't severely wear the tires is testing something less than the MAX.
