This might help those of you mathematical-type people.
The SVX tire, at 255/50/16, spins about 811 times per mile. At 60 mph, you are traveling at one mile per minute. That equals 13.5167 wheel rotations per second. However, the stock wheel has five spokes. This gives each spoke a "Hz" value of 67.5833. At 60 miles an hour, the wheel should still appear to be spinning forward. At 65 mph, you are traveling at a rate of 1.0833 miles per minute. That gives the wheels 14.6431 rotations per second. This now gives the spokes a "Hz" value of 73.2153. At this rate the wheel will appear to either be spinning backwards very, very slowly, or appear to be stationary. Remember, if your vision's "refresh rate" is at 72Hz, the spokes will almost appear to be in the exact same location, as in the previous "frame," at this speed. At 70 mph, you are traveling at a rate of 1.1667 miles per minute. The wheels spin at 15.7694 times per second. The spokes are now at 78.8472. They will either appear to be spinning backwards, or will be too fast and become a blur in your vision. So, if you could watch the wheels on a SVX that is accelerating from 60 > 65 > 70, you would see them go from forward, to stationary for just one fraction of a second, to "backwards." Watch another cars wheels accelerate on the freeway. They always have this pattern. The SVX is, theoretically however, in the 60 - 70 mph range for this sequence to occur. I hope I didn't suck at explaining this. |
