but after you factor in food, fuel, oxygen used, heartbeats per minute, rotational mass of your lug nuts, air speed of an african swallow, breakdown of engine oil viscosity per mile dependent on revolutions per minute, amount of lumens produced by headlights to calculate effects on fuel mileage, wear and tear on wheel bearings according to weight displacement per wheel, load vs temperature and it's effect on tire wear...you'll pretty much decide it's too expensive to go.Originally Posted by Chadnutz
