How to Choose Tires for Your Scat Pack

Before you look at a single tire, confirm your exact factory size from the door jamb placard — not the internet. Standard-body Charger Scat Packs run 245/45R20 all around on 20×8-inch wheels. The Scat Pack Widebody runs 275/40R20 fronts and 305/35R20 rears on significantly wider 10- and 11-inch wheels. These are different tire families entirely. Buying the wrong size means returning them before they ever touch your car. Also note your wheel's offset — this matters if you're considering any size upgrade or stagger setup.

This decision shapes everything that follows. Summer tires (Michelin Pilot Sport 4S, Pirelli P Zero) are made from compounds that grip best above 45°F — they're softer, stickier, and dramatically better in the dry and wet at performance temps. Below 45°F, the compound hardens and grip plummets — they become genuinely dangerous in cold or snowy conditions. All-season tires trade some performance for year-round versatility — solid choice if you drive the Scat Pack daily through winter. Performance all-season (Michelin Pilot Sport All Season 4, Continental ExtremeContact DWS06+) is the best middle-ground: real performance capability without the seasonal restriction.

Tires are tiered by intended use intensity. Grand Touring tires prioritize long tread life and ride comfort — not appropriate for a 392 HEMI. Ultra-High Performance (UHP) tires are the correct category for the Scat Pack: designed for performance vehicles, with compounds and construction tuned for lateral grip and steering response. Max Performance tires push further — street-legal track compounds with extremely high grip and short tread life, suited for HPDE or occasional track use. For most Scat Pack owners, UHP Summer or UHP All-Season is the right tier.

The Scat Pack's 392 HEMI makes 485 HP and 475 ft-lbs of torque — it will expose any tire weakness in a hurry. If your driving is primarily street and occasional canyon runs, a premium UHP summer tire like the Pilot Sport 4S or Pirelli P Zero gives you the best overall experience. If you attend track days or HPDE events regularly, a Max Performance tire like the Michelin Pilot Sport Cup 2 or Continental SportContact 6 will hold up better under sustained heat load. If you daily drive through winter, don't fight it — a quality UHP all-season gives you 80% of the summer tire's performance and 100% of the functionality you need in November.

The 392 HEMI Charger weighs approximately 4,400 lbs. For the stock 245/45R20 size, look for a minimum load index of 99 (1,709 lbs per tire) which provides comfortable margin at that vehicle weight. Never go below the factory-specified load index — it's a safety floor, not a suggestion. For speed rating, the factory specifies W (168 mph) or Y (186 mph) rated tires. Both are appropriate for street use. Z or Y-rated tires are recommended if you ever push the car at sustained high speed on a track or open road. The speed rating also correlates to compound construction quality in most cases — higher-rated tires tend to perform better dynamically.

If you're on the standard-body Scat Pack and want more rubber, the safe rear upgrade is 275/40R20 — a modest width increase that clears the stock wheel arches without cutting or flaring. Going to 305 on the rear requires Widebody flares. On the front, 245/45R20 is usually the practical limit without rubbing during lock-to-lock steering. A staggered setup (wider rear than front) is very popular on RWD muscle cars for traction and aesthetics — just be aware that staggered fitments cannot be rotated front-to-back, so you'll replace fronts and rears at different times.

Premium tire brands back their products with mileage warranties — Michelin and Continental typically offer 30,000–45,000-mile warranties on their UHP summer lines. Road hazard protection (available as an add-on from most shops) covers pothole damage and sidewall punctures — absolutely worth it on low-profile 20-inch tires that are vulnerable to impact damage. Build your total cost per tire: purchase price + mount and balance + disposal + road hazard coverage. A $50 cheaper tire with a shorter warranty and no road hazard often costs more per mile over its life. Budget $900–$1,400 all-in for a quality set of four UHP summer tires installed on a Scat Pack.
