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
28.4" overall diameter affects speedometer reading, gearing feel, and clearance. Keep front/rear diameters close unless the setup is intentionally staggered.

What Does This Do?
Mickey Thompson's ET Street SS is purpose-built for drag strip launches on a street-legal tire. The ultra-soft compound grips the prepped surface like glue — on a properly prepped strip, these can cut 1.0-1.5 seconds off your 60-foot time compared to regular tires, which translates to massive quarter-mile improvements. The 305/35 R20 size fits the stock 20" rear wheels on Scat Pack and Hellcat models. They're DOT-approved (street legal) but they're NOT daily-driver tires — the soft compound wears quickly on regular roads, they're terrible in rain, and they need to be heated up (burnout) before each pass for best grip. Rear-only installation.
Why Install This?

- Maximum straight-line traction for consistent launches
