Reapply the identical load, and with out interruption or readjustment of inflation pressure, rotate the take a look at wheel at 375 rpm for half-hour, then at 400 rpm for half-hour, and then at 425 rpm for 30 minutes. Our 1/3-mile per lap check track course consists of 90-degree street corners, a five-cone slalom and simulated expressway ramps.
