Description
The Mickey Thompson ET Street R P305/45R17 is a street-legal drag radial engineered to deliver serious traction for high-horsepower street and strip vehicles. Built with Mickey Thompson’s proven R2 race compound and a minimal tread-void design, the ET Street R maximizes tread contact to help transfer more power to the pavement during hard launches and acceleration. This P305/45R17 size features a 28.1-inch overall diameter, 11.7-inch section width, and 10.5-inch tread width, giving properly configured Gen 3 HEMI applications a substantial contact patch without requiring a 15-inch drag wheel conversion. Tubeless radial construction eliminates the added expense and complexity of an inner tube while providing the radial characteristics many modern performance enthusiasts prefer. For Hellcat, Redeye, Demon, Scat Pack, and other high-output HEMI combinations, the ET Street R offers a proven way to turn horsepower into usable traction.
As Gen 3 HEMI power levels increase, getting that power to the ground can quickly become just as important as making it. Pulley upgrades, E85, supercharger modifications, camshafts, nitrous, forced induction, and custom tuning can all push a combination beyond what a conventional street tire can effectively manage. The ET Street R is designed specifically around straight-line traction, making it a strong choice for performance vehicles that regularly see the drag strip.
Mickey Thompson equips the ET Street R with its R2 compound, a specialized drag-racing compound used across the ET Street R, ET Street S/S, and ET Street Radial Pro families. Combined with the tire’s wide contact area and minimal tread void, the R2 compound is designed to put more rubber against the racing surface for improved traction where it matters most.
The P305/45R17 is equivalent to a 28X12.50R17 and provides a useful combination of width and overall diameter for powerful modern muscle cars. Mickey Thompson lists the tire at 28.1 inches tall with an 88.3-inch circumference, 11.7-inch section width, and 10.5-inch tread width. This sizing can make it especially attractive for Gen 3 HEMI owners looking for a substantial rear tire while retaining a 17-inch wheel.
Proper wheel selection remains critical for performance and safety. Mickey Thompson measures the P305/45R17 on a 10-inch-wide wheel and approves it for wheel widths ranging from 9.5 to 11.5 inches. Actual vehicle fitment depends on wheel offset, backspacing, suspension configuration, brake clearance, ride height, and available body clearance.
The ET Street R is also DOT-approved for street use, providing additional versatility for vehicles that see both the street and drag strip. Its tubeless construction simplifies installation, but its race-oriented compound and minimal tread pattern mean this is still a specialized performance tire designed primarily around dry traction rather than all-weather street driving.
For Gen 3 HEMI owners who have already invested in making more power, the Mickey Thompson ET Street R P305/45R17 provides the compound, footprint, construction, and drag-focused design needed to make better use of that performance at the track.
