Most Popular Aftermarket Setups
OEM+ Wide Tire Upgrade (Narrowbody) The most common upgrade uses a staggered setup: 20x9.5" front with 275/40R20 (stock) and 20x10.5" rear with 305/35R20. This maintains factory front feel while dramatically improving rear traction.
Example: 20x10.5" +20 offset rear wheels with 305/35ZR20 Nitto tires, paired with stock fronts. This setup sits nearly flush with stock fenders and eliminates rubbing issues while providing much improved rear grip.
Square Rotatable Setup (Widebody) Many widebody owners choose 20x11" +15 to +3 offset wheels with 305/35R20 tires all around. This allows tire rotation and balanced handling.
APEX Race Parts developed a track-oriented setup using 20x11.5" ET3 wheels with 315/35ZR20 tires square. This fits widebody fenders with proper offset and some negative camber dialed in front.
Drag Racing Configuration Dedicated drag setups typically use 18x10" or 18x11" rear wheels with 305/45R18 or 315/40R18 drag radials. The taller sidewall improves launch characteristics by absorbing shock and widening the contact patch.
Weld Racing-off-road-chasm-8x165-1-18x10-18-gloss-black-milled-windows/)-off-road-chasm-8x165-1-18x10-18-gloss-black-milled-windows/) makes forged 18x11 wheels specifically designed to clear Hellcat brakes. These cost around $1,300 each but bolt on without brake interference.
Maximum Aggressive Fitment Limits
Narrowbody (Stock Fenders)
- Rear maximum: 11" wide wheel, +20 to +25 offset with 315mm tire
- Front maximum: 10" wide wheel, +20 offset with 285-295mm tire
- Requires careful offset selection and possibly fender lip rolling
One documented example: 315/35R20 Pirelli P Zeros on 20x11" +24 wheels. This setup worked but left minimal inner clearance - slightly narrower tires from other brands would be safer.
Widebody (OEM Flares)
- Maximum tested: 12" wide wheel, 0 offset with 335mm rear tire
- Front capability: 11.5" wheel with 315mm tire (requires spacer and camber)
- APEX testing confirmed 325/30ZR20 tires work all around with minor modifications
With Custom Flares Adding aftermarket flares like Phillips "Lil' Devil" kit allows 295/35R20 front and 335/30R20 rear tires on previously narrowbody cars. This exceeds even factory widebody capability.
Tire Selection by Use Case
Street Performance (Summer Tires)
- Michelin Pilot Sport 4S:** Gold standard for street/occasional track use
- Continental ExtremeContact Sport:** Excellent dry grip, superior wet handling
- Bridgestone Potenza Sport:** Comparable dry performance to Michelin
- Nitto NT555 G2:** Budget-friendly option for frequent tire replacement
Drag Racing (Drag Radials)
- Mickey Thompson ET Street R:** Nearly full slick with minimal tread
- Nitto NT555RII:** Slightly harder compound for better street manners
- Mickey Thompson ET Street SS:** More street-oriented drag radial
Warning: Drag radials are dangerous in wet conditions and feel sloppy in corners due to soft sidewalls.
Track/Autocross
- Michelin Pilot Sport Cup 2:** Street-legal track tire
- Toyo Proxes R888R:** High-temperature capable
- Yokohama Advan A052:** Time-attack favorite
All-Season Performance
- Michelin Pilot Sport All Season 4:** Excellent cold/wet performance
- Continental ExtremeContact DWS 06 Plus:** Great tread life and comfort
- Both available in 305/35R20 and 315/35R20 for widebody applications
Using Spacers and Adapters Safely
When Spacers Are Needed
- Correcting wheels with excessive positive offset
- Clearing brake calipers or suspension components
- Fine-tuning flush fitment (3-5mm spacers common)
Quality Brands
- Eibach Pro-Spacer:** Hub-centric design, $200-250 per pair
- H&R Trak+ Spacers:** Proven reliability
- BORA/Motorsport Tech:** Custom-made high-grade spacers
Critical Requirements
- Hub-centric design for 71.5mm Challenger hubs
- Proper thread engagement (minimum 7-8 full turns)
- Re-torque after 50-100 miles of driving
Bolt Pattern Adapters Converting from 5x115 to 5x114.3 requires proper adapters - never force mismatched patterns. Quality adapters are typically 20-25mm thick and provide new studs in the desired pattern.
Suspension Impact on Fitment
Lowering Springs Dropping the car 1-1.5" naturally adds negative camber, which can help fitment by tucking tire tops inward. However, reduced suspension travel means less clearance during compression.
Popular options include Eibach Pro-Kit and H&R Springs, typically lowering 1.1" front and 0.8" rear.
Coilovers Adjustable height coilovers offer more control and often include camber adjustment. Stiffer spring rates reduce body movement, helping maintain clearance with aggressive fitments.
Alignment Considerations After lowering, expect natural camber changes from -0.5° to approximately -1.0° front, -1.5° rear. Performance alignments often run -1.5° front, -1.0° rear for better handling and front fender clearance.
Common Mistakes to Avoid
Hub Bore Issues Always use hub-centric rings when aftermarket wheels have larger center bores than 71.5mm. Failure to center wheels properly causes vibration at highway speeds.
Wrong Bolt Pattern Never force 5x114.3 wheels onto 5x115 hubs. The 0.7mm difference stresses lugs and can cause failure. Use proper adapters or find correct pattern wheels.
Cheap Wheel Quality Budget replica wheels can crack under the Hellcat's weight and power. Stick to reputable brands like Factory Reproductions, MRR%20wheels), or Voxx%20wheels) for replicas, or invest in forged wheels for maximum strength.
Improper Tire Sizing Avoid extreme stretching (275 tire on 11" wheel) or pinching (315 tire on 9.5" wheel). Stay within manufacturer's approved rim width ranges for safety and performance.
Ignoring Load Ratings Ensure tires have sufficient load index (100+) and speed rating (Y-rated for 186+ mph) for the Hellcat's weight and capability.
Where to Buy Quality Wheels
Large Retailers Tire Rack, Fitment Industries, and American Muscle offer extensive catalogs with known fitments and customer galleries. Good for common setups and competitive pricing.

Show Car Builders Custom offset wheels allow perfect flush fitment and unique aesthetics impossible with off-the-shelf options.
When to Keep Stock Wheels
Daily Driver Priority Stock wheels offer excellent ride quality, proven durability, and easy tire replacement. The factory setup handles 707hp adequately for street driving.
Budget Constraints Quality aftermarket wheels cost $2,000-8,000+ for a complete set. Stock wheels retain good resale value if kept in excellent condition.
Warranty Concerns Some dealers may question warranty claims if aftermarket wheels contributed to suspension or drivetrain damage.
Final Verdict
The Hellcat's wheel fitment offers tremendous flexibility, from conservative OEM+ upgrades to extreme custom builds. Narrowbody cars can accommodate up to 315mm rear tires with proper wheels, while widebody models handle 335mm tires with aggressive offsets.
Success depends on understanding the relationship between wheel width, offset, and tire size. Quality components from reputable manufacturers ensure safety at the Hellcat's extreme performance levels.
