The Tire Retread Information Bureau's tire thumping contest at the recent Mid-America Trucking Show produced zero winners.
Contestants tried to determine the pre-set inflation pressure of a truck tire by giving the tire a good "thump."
"Those coming within plus or minus five psi of the pre-set inflation pressure would receive a nice prize," says Tire Retread Information Bureau (TRIB) Managing Director Harvey Brodsky.
"Not surprisingly, no one came within five psi of the air pressure in any of the tires.
"Inflation pressure cannot be accurately estimated by kicking or thumping the tire.
"Trying to determine if tires need air by thumping them is as effective as trying to determine of a vehicle's engine needs oil by thumping on the hood."
More than 25 truckers took part in the contest.
