Here's a look at both versions of Nitto's NT05 tire, the street tire at left and NT05R drag radial on the right. As you can see, the NT05R shares a somewhat similar tread pattern as its street sibling. From an overall construction standpoint, the shoulder treads and center ribs on each tire differ the most. While the DR has a much wider center section and softer compound for maximum grip with the strip, the NT05 street tire features a reinforced shoulder for improved rigidity and stability in dry-road, high-speed driving conditions. The tires are alike in that they're both not the most-comfortable or quietest tires in Nitto's street and competition families. Tire noise is considerable from both, especially when driving in 65- to 70-mph freeway conditions.
