Share Article

ATA Associates' paper "Effect of Directional Tires on Wet Traction" was recently published by Rubber and Plastic News in their July 27th 2009 Technical Notebook. 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.

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

ATA Associates' paper "Effect of Directional Tires on Wet Traction" was recently published by Rubber and Plastic News in their July 27th 2009 Technical Notebook. 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 Rubber and Plastic News. As engineers and scientists, it is our responsibility to share our technical results with the public," said Swint.

Founded in 1971, Rubber & Plastics News serves rubber product manufacturers primarily engaged in the production of tires and inner tubes, rubber and plastic footwear, reclaimed rubber, rubber and plastic hose and belting, fabricated rubber products, rubber adhesives and wire and cable products.
