Beware Motorcoaches Exceeding Tire Load Ratings

Federal Motor Carrier Safety Regulations (49 C.F.R. § 393.75) prohibit motorcoaches from carrying a weight greater than that marked on the tire or operating with damaged or dangerously worn tires.

A tire loaded beyond its carrying capacity and operated at highway speeds is more likely to overheat and fail, placing the lives of passengers and other motorists at risk. This is particularly critical during the hot summer months.

Before every trip, motorcoach operators should consider maximum tire load carrying capacity and tire speed rating, and allow an adequate tire pressure safety margin when carrying maximum passenger and luggage loads.

Motorcoach operators that violate applicable tire loading restrictions may face enforcement action pursuant to 49 U.S.C. § 521.
