WASHINGTON-Transporters of manufactured homes will have to use larger, stronger tires and give them lighter loads under regulations proposed jointly by the Federal Highway Administration and the Department of Housing and Urban Development. Under the proposal issued April 24, house transporters will have to use 8-14.5 MH (Mobile Home) Series E, 10-ply tires, replacing most of the currently used 7-14.5 MH Series D, 8-ply tire and 8-14.5 MH Series D, 8-ply tires. Maximum load will be reduced to 3,000 pounds from the current 3,810.
When the load on any manufactured home tire exceeds 2,769 pounds, maximum speeds will be limited to 50 mph.
For the first two years after the rule goes into effect, the FHWA and HUD will limit overloading of manufactured home tires to 18 percent.
During that time, the agencies will study test and technical data to determine the relative performance of tires overloaded by 18 percent against those not overloaded.
The agencies expect to issue a final rule on this matter late this year or early next, with the effective date nine months after issuance.
