The Mickey Thompson ET Street R P315/60R15 is a serious drag radial engineered to put high horsepower to the pavement while retaining DOT approval for street use. Built around Mickey Thompson’s proven R2 race compound, the ET Street R uses minimal tread void to maximize the amount of rubber making contact with the track and deliver the traction hard-launching performance vehicles demand. This specific P315/60R15 size provides a large 30.1-inch overall diameter, 13.3-inch section width, and 11.7-inch tread width, making it a strong option for properly configured high-horsepower Gen 3 HEMI applications. Tubeless radial construction eliminates the expense and complexity of an inner tube while providing a dependable seal when mounted to a compatible wheel. For Hellcat, Redeye, Demon, Scat Pack, and other powerful HEMI builds equipped with the proper 15-inch wheel and suspension setup, the ET Street R provides the traction needed to make better use of the power you’ve built.

Power means very little at the drag strip if the tire cannot transfer it to the track. As Gen 3 HEMI combinations progress from basic bolt-ons and tuning to camshafts, E85, nitrous, supercharger upgrades, and other high-output modifications, traction can quickly become one of the largest limitations. The ET Street R is designed specifically around straight-line performance, giving serious street and strip combinations a tire built with drag racing priorities in mind.

Mickey Thompson uses its R2 compound on the ET Street R, a specialized compound shared with the ET Street S/S and ET Street Radial Pro families. Combined with a minimal tread-void design and wide contact area, this construction places a substantial amount of rubber against the racing surface to help improve traction during hard launches and acceleration.

The P315/60R15 size is particularly attractive for performance vehicles that can accommodate a large 15-inch rear tire. Mickey Thompson lists it as the equivalent of a 30X13.50R15, with a 30.1-inch overall diameter and 94.5-inch circumference. The tire measures 13.3 inches at the section and provides an 11.7-inch tread width, giving high-powered combinations a substantial footprint for transferring power.

Proper wheel selection is critical. Mickey Thompson measures this tire on a 9.5-inch-wide wheel and approves it for wheel widths ranging from 8.5 to 11.0 inches. On Gen 3 HEMI platforms, a 15-inch drag wheel conversion may require specific brake, suspension, wheel offset, backspacing, and clearance considerations. Fitment should always be confirmed for the exact vehicle before ordering.

Despite its competition-focused design, the ET Street R is DOT approved for street use. Mickey Thompson also specifies tubeless construction, which simplifies installation compared with a tube-type drag tire. However, this remains a highly specialized performance tire, and its minimal tread pattern and race-oriented compound make it best suited to enthusiasts prioritizing maximum dry traction and drag strip performance rather than all-weather street driving.

For properly configured Gen 3 HEMI builds struggling to translate horsepower into forward movement, the Mickey Thompson ET Street R P315/60R15 delivers the footprint, compound, construction, and drag-focused design needed to help make that power usable where it counts.
