- Suppose you were planning to move a house by transporting it on a large trailer. The house has an estimated weight of 52.3 tons. The trailer is expected to weigh 6.4 tons. Each wheel of the trailer will have tires inflated to a gauge pressure of 86 psi (which is actually 86 psi above atmospheric pressure). If the area of contact between a tire and the pavement can be no larger than 100.0 in² (10.0 in. x 10.0 in.), what is the minimum number of wheels that trailer must have?
