Suburbanites living downwind from large cities should seriously consider wet-weather tyres according to Goodyear. Citing recent research by NASA, Goodyear says that it rains more – sometimes a lot more – for several miles downwind from large cities.

The NASA scientists, using satellite measurements, have confirmed reports based on rain gauges that indicate these city-related wet spots exist. The NASA study found that rainfall downwind from studied cities averaged 28 percent more than an area upwind. Some areas showed increases of as much as 51 percent.

Cities tend to be 1 to 10 degrees (F) warmer than the suburbs, and that’s what makes for the extra rain, NASA researchers say. They found that the average monthly rainfall rates were increased 18 to 36 miles downwind of the cities they studied.

Goodyear is seizing on the results of the research to promote its Aquatred tyres. The company says it has revamped its Aquatred tires to handle changing climate data, which revealed America is getting more of its rainfall in heavy downpours than early in the last century.
