The Mickey Thompson ET Street R 315/50R17 is a D.O.T. approved drag radial engineered for racers who need maximum straight-line traction from a tire that can also be driven on the street. Built with Mickey Thompson’s proven R2 drag racing compound, the ET Street R combines a wide contact area with minimal tread void to put as much rubber as possible against the racing surface. This specific 315/50R17 configuration measures approximately 29.4 inches tall with a 12.7-inch section width and 11.2-inch tread width, giving high-horsepower vehicles a substantial footprint for hard launches and acceleration. Radial and tubeless construction make it a practical choice for street and strip combinations without requiring the tubes associated with some dedicated racing tires. For powerful Gen 3 HEMI platforms such as the Challenger Hellcat, Charger Hellcat, Scat Pack, and other properly configured Dodge applications, the ET Street R provides a proven solution for turning horsepower into usable traction.

Making more horsepower is only valuable when the vehicle can transfer that power to the pavement. Modified Gen 3 HEMI combinations can quickly overwhelm conventional performance street tires, especially when adding supercharger pulleys, E85, camshafts, larger superchargers, nitrous, or other substantial power upgrades. The resulting wheelspin can hurt 60-foot times, consistency, and overall elapsed time even when the engine is producing significantly more power.

The ET Street R 315/50R17 is built specifically for drivers prioritizing straight-line performance. Mickey Thompson’s R2 compound is a specialized drag racing compound used in the ET Street R, ET Street S/S, and ET Street Radial Pro families. Combined with the tire’s minimal tread void and wide contact area, this compound helps maximize available traction when launching and accelerating down the track.

This particular size has a 315/50R17 designation and a 30X13.50R17 equivalent size. Mickey Thompson specifies a 10-inch measuring rim, with an approved rim-width range of 8.5 to 11 inches. The tire measures approximately 29.4 inches in overall diameter, 12.7 inches in section width, and 11.2 inches across the tread, with a circumference of approximately 92.4 inches. Approximate tire weight is 35 pounds.

Those dimensions make the 315/50R17 an attractive option for high-powered Gen 3 HEMI vehicles using an appropriately configured 17-inch rear drag wheel. The nearly 30-inch overall diameter can also influence effective gearing and engine RPM through the quarter mile, making tire diameter an important consideration when developing a complete drag racing combination. Wheel width, offset, backspacing, brake clearance, suspension setup, and body clearance should always be verified before installation.

The ET Street R is D.O.T. approved for street use and features tubeless construction, giving racers the ability to use the same tire for limited street driving and trips to the track. However, this remains a competition-focused tire with minimal tread void, so dry-weather traction and drag racing performance take priority over wet-weather capability and conventional street-tire longevity.

For Gen 3 HEMI owners who have reached the limits of their street tires, the Mickey Thompson ET Street R 315/50R17 delivers a purpose-built combination of R2 compound technology, a wide footprint, radial construction, and race-proven traction designed to help put serious horsepower to the ground.
