P275/40R17 ET Street R Tire

The P275/40R17 ET Street R Tire by Mickey Thompson is purpose-built for serious drag racers and street performance enthusiasts who demand maximum traction off the line. This radial slick combines DOT legality with track-proven grip, making it the go-to choice for modified muscle cars, street outlaws, and weekend bracket racers running dedicated 17-inch wheels. Whether you're launching a turbocharged small-block or a supercharged big-block, the ET Street R delivers the sidewall compliance and compound technology needed to hook hard and stay planted through the 60-foot zone.

Mickey Thompson engineered the ET Street R with a softer rubber compound and optimized tread pattern designed to flex and conform to track surfaces, transferring engine power to the pavement with minimal wheelspin. The 275-millimeter width provides a generous contact patch, while the 40-series sidewall ratio balances comfort with structural integrity—critical for absorbing the violent forces of hard acceleration without blowouts. At 27 pounds per tire, the P275/40R17 ET Street R maintains manageable unsprung weight while the reinforced construction withstands repeated burnouts, launch loads, and the thermal cycles of competitive driving.

Street racers, drag strip regulars, and performance shops specify the P275/40R17 ET Street R when stock rubber won't cut it—ideal for vehicles with upgraded suspension geometry, adjustable control arms, and tuned powerplants making 400+ horsepower. Installation on 17-inch performance wheels is straightforward; verify your vehicle's load rating and wheel offset before fitment to ensure proper clearance within fenders and suspension components. For best results, maintain proper inflation pressure, rotate between qualifying rounds, and allow cooling periods between hard launches to maximize tire life and consistency at the starting line.
