Drag or track-focused setup
This is better treated as a special-purpose setup, not a simple daily-driver replacement. Confirm wheel diameter, brake clearance, and front/rear pairing.
Wheel width pairing
305mm tires are usually paired with roughly 10"-11.5" wide wheels. Use this as a pairing check, not a guarantee.
Overall diameter
27.6" overall diameter affects speedometer reading, gearing feel, and clearance. Keep front/rear diameters close unless the setup is intentionally staggered.

What Does This Do?
The Mickey Thompson ET Street S/S Tire is a specialized tire designed for high-performance driving, providing excellent grip for both street and drag strip use.

Who it's for: This tire is perfect for car enthusiasts who want to use their Dodge Challenger for both daily driving and occasional drag racing.
