P225/50R15 ET Street R Tire

The P225/50R15 ET Street R Tire from Mickey Thompson is engineered for serious performance driving and competition use on paved surfaces. Built for enthusiasts who demand maximum grip during acceleration, braking, and cornering, this tire bridges the gap between street performance and drag strip capability. Whether you're upgrading a modified muscle car, bracket racer, or high-powered street machine, the ET Street R delivers the traction you need when it matters most.

Mickey Thompson's ET Street R uses a specialized rubber compound and aggressive tread design optimized for launch grip and sustained acceleration loads. The 225/50R15 fitment is a popular choice for modern performance vehicles and restomod builds, offering a low-profile sidewall that reduces flex under hard acceleration while maintaining responsive handling characteristics. At 23 lbs per tire, the relatively light weight minimizes rotational inertia—critical for quarter-mile performance and throttle response. The R-compound construction resists heat buildup during sustained high-power driving, making it superior to street radials for sustained performance applications.

This tire is ideal for dedicated performance vehicles that see occasional street use but spend time at the track or drag strip. It suits owners of turbocharged and supercharged applications where consistency and predictable grip matter as much as ultimate adhesion. Installation requires proper wheel alignment and balance; verify your vehicle's load rating and speed rating compatibility before purchase. ET Street R tires excel on vehicles between 2,500 and 5,000 lbs with horsepower outputs demanding serious traction management.
