Effect of Directional Tires on Wet Traction
Houston, TX (Vocus) June 10, 2010
ATA Associates’ paper “Effect of Directional Tires on Wet Traction” was recently published in the in the Spring 2010 issue of Collision, The International Compendium for Crash Research. Written by ATA’s Bob Swint and Ed Fritsch, in partnership with Bobby Unser and Harold Herzlich, the paper describes tests looking for quantifiable differences in braking and handling performances related to the specific orientation of directional tires.
The study was litigation related and designed to test reversed rotation with regard to wet braking and wet lane change. At issue in Poole v. Pep Boys (No. 06-03657-E, District Court of Dallas County, Texas 101st Judicial District) was the claim that improper mounting of a directional tire was responsible for an unfortunate motor vehicle accident.
“ATA performed straight-line braking tests and lane change maneuvers with various brands of tires and plotted the trajectory of the vehicles. Testing at the site and two additional testing locations revealed no significant decrease in performance associated with directional tires and wet surface handling,” according to Swint. The paper further addresses hydroplaning, tread depth and pattern, as well as the coefficient of friction of road surfaces.
“We are pleased to have our finding published in Collision. Collision leads the industry in crash data research,” said Swint. “I highly recommend the magazine to attorneys, insurance personnel, and reconstructionists for keeping current on the latest technical data and analysis.”
