Anyone know how much the tire alone in the size of 225/60/16 weighs? I did some weighing today and found my aluminum rims with tire weigh 45lbs each, and my full size steel rim spare with tire weighs 50lbs. I'm trying to figure out what my rims weigh on there own. Does anyone know how much the stock steel 16 inch rims weigh? I could figure it out like that too.
