Message	Tire Circumference for 245/45/16: Profile height: 245mm width x .45 = 110.25mm side wall heigth x 2 sides(top/bottom) = 220.5mm / 25.4 to convert mm to inches = 8.68" for the tire + 16" for the wheel = 24.68" / 12" to convert to feet = 2.06 x pi(3.1416) to convert to circumference = 6.461 feet. The rest is easy: rpm x tire circumference / gear ratio / final drive / 88. AUTO = 7,000 * 6.461 / 0.75 / 3.69 / 88 = 173.06 MAN = 7,000 * 6.461 / 0.69 / 3.69 / 88 = 188.11
