2018 Chrysler 300 Wheel Interchange

2018 Chrysler 300 Wheel Fitment Guide - wheelinterchange.com

Known OEM Fitment For 2018 Chrysler 300

The values below are sourced from available OEM data for the 2018 Chrysler 300. Trims and option packages can change wheel and tire specs. If something is not listed or looks inconsistent, it likely varies by trim. Always confirm your exact configuration using your door jamb tire placard, the owner manual, a dealer lookup by VIN, and the on-page calculator.

Note: The sample wheel size shown is 18 inches while the sample tire size is a 17 inch fitment. This reflects different trims or packages in the model year. Your vehicle may have come with 17, 18, or other factory sizes. Verify what your specific car uses, then use the calculator to compare alternatives safely.

How To Use The Wheel Interchange Calculator

The calculator helps you compare a potential donor wheel and tire to your 2018 Chrysler 300. It visualizes changes in clearance, poke, and tire diameter so you can make safe choices before buying.

• Installed on your vehicle - Select 2018 Chrysler 300 to anchor the comparison to your car.
• Wheels from donor vehicle - Choose the vehicle you want wheels from, or enter a custom spec.
• Custom wheel size - Adjust rim diameter, width, and offset. The tool updates backspacing and how far the wheel moves inboard and outboard.
• Custom tire size - Enter section width and aspect ratio. If you change rim diameter, the calculator updates overall tire diameter in the comparison so you can assess speedometer impact and fender clearance.
• Review outputs - Check inner clearance to suspension and brakes, outer poke toward the fender, and tire diameter difference versus your verified OEM size.
• Decide with data - If clearances are tight or the diameter change is large, select a different offset, width, or tire profile until the results align with safe margins.

Fitment Checklist Before You Buy

• Pattern and hub - 5x115 bolt pattern and 71.6 mm hub bore. If an aftermarket wheel has a larger center bore, plan for quality hub-centric rings to 71.6 mm.
• Brake clearance - Confirm spoke and barrel clearance over calipers and rotors. Test fit a bare wheel when possible.
• Offset and backspacing - Compare ET and backspacing to OEM using the calculator. Ensure inner barrel does not contact struts, knuckles, or liners, and that outer poke does not hit fenders.
• Tire diameter - Keep overall diameter close to your verified OEM size to help maintain speedometer accuracy, gearing, ABS, and traction control behavior.
• Load index and speed rating - Tires and wheels must meet or exceed OEM load and speed ratings for safety.
• TPMS - If your car is equipped with TPMS, you will need compatible sensors or to transfer your originals. Confirm by VIN or owner manual.
• Lug hardware - Thread is M14 x 1.5. Match the lug seat style to the wheel seat type, and ensure proper thread engagement. Do not mix seat styles.
• Brake and suspension mods - Big brake kits, lowering springs, and coilovers can change required clearances. Recheck after any modification.
• Test under load - After fitting, turn lock to lock and compress the suspension to check for rubbing at full bump and steering angles.

Plus Sizing And Common Upgrades

Many owners explore plus sizing for a sharper look and handling. Because 2018 Chrysler 300 trims shipped with differing OEM wheel and tire sizes, first confirm what your car actually has, then use these guidelines with the calculator:

• Plus one or plus two - Increasing rim diameter usually means reducing tire sidewall height to keep overall diameter close to stock.
• Width changes - Wider wheels and tires can improve grip but require careful offset selection to avoid fender or suspension contact.
• Ride and comfort - Lower profile tires can firm up ride and increase impact sensitivity. Consider your roads and priorities.
• Seasonal sets - For winter, some drivers prefer narrower tires for snow traction. Keep the load index at or above OEM and maintain adequate brake clearance.
• Use the calculator - Iterate wheel width, offset, and tire profile to balance appearance, clearance, and handling while staying near your OEM tire diameter.

Installation Tips

• Clean mounting surfaces - Remove rust and debris from the hub face and wheel mounting pad for true seating.
• Hub-centric rings - If your wheels have a larger bore than 71.6 mm, install quality rings so the wheel centers on the hub.
• TPMS - Transfer or program compatible sensors before mounting tires. Follow the vehicle’s relearn procedure as specified by the manufacturer.
• Lug torque - Install lug nuts by hand, snug in a star pattern, then torque to the OEM specification from your owner manual. Re-torque after 50 to 100 miles.
• No impact final torque - Use a calibrated torque wrench for final tightening on clean, dry threads unless the OEM specifies otherwise.
• Final checks - After installation, verify no rubbing at full lock and over bumps. Monitor for vibration and address via rebalancing or hub-centric correction.

Tools And Helpful Supplies

• 1/2 inch drive click torque wrench
• M14 x 1.5 lug nuts - match seat style to your wheels
• Hub-centric rings 71.6 mm ID - choose OD to match your wheel bore
• TPMS rebuild kit or service kit

FAQs

• What is the bolt pattern for the 2018 Chrysler 300?

  5x115.

• What center bore do I need?

  71.6 mm. If your aftermarket wheel has a larger bore, use hub-centric rings to 71.6 mm so the wheel centers properly on the hub.

• What lug nuts does it use?

  M14 x 1.5 thread. The lug seat style must match the wheel seat style. If your new wheels have a different seat type than OEM, buy the correct matching lug nuts or bolts for those wheels.

• What is the factory offset?

  Available data shows ET 24 mm on an 18 x 7.5 inch example wheel. Offset can vary by trim or package. Verify your exact OEM wheel specs by VIN, owner manual, or door placard, then use the calculator for comparisons.

• Did the 2018 Chrysler 300 come with 17 inch or 18 inch wheels?

  OEM information for this model year shows both 17 inch tire data and 18 inch wheel data, which indicates multiple factory configurations. Check your door jamb tire placard and owner manual to confirm what your vehicle was built with.

• Can I use 5x114.3 wheels on a 5x115 car?

  Do not mix bolt patterns. Use only wheels that match 5x115 to maintain proper clamping and safety.

• Do I need hub-centric rings with aftermarket wheels?

  Use rings if the wheel’s center bore is larger than 71.6 mm. If the wheel is already 71.6 mm and designed for this hub, rings are not needed.

• What is the correct wheel torque?

  Follow the torque specification in your owner manual or service information for the 2018 Chrysler 300. Tighten in a star pattern and re-torque after 50 to 100 miles.

• How close should my new tire diameter be to stock?

  Keep overall diameter as close as practical to your verified OEM tire size to help maintain speedometer accuracy and proper ABS and stability system operation. Use the calculator to quantify the difference.

• Will wider wheels fit without rubbing?

  It depends on offset, tire profile, and your specific brakes and suspension. Use the calculator to model inner and outer clearance and always test fit before mounting tires.
