2021 Chrysler 300 Wheel Interchange

Known OEM Fitment For 2021 Chrysler 300

The figures below are supplied data points for at least one OEM configuration of the 2021 Chrysler 300. Trim and package variations can change wheel, tire, and brake clearances. If a value is missing for your specific vehicle or looks inconsistent, confirm what is physically on your car and verify with the on-page calculator plus OEM sources such as the owner manual or dealer parts catalog.

Important: The presence of both an 18x7.5 wheel spec and a 215/65R17 tire spec indicates multiple OEM setups exist. Check the sidewall of your current tires and the stamping on your wheels to confirm your starting point. If uncertain, use your VIN with a Chrysler dealer to retrieve the exact OE wheel and tire specification for your trim.

How To Use The Wheel Interchange Calculator

The calculator compares a donor wheel and tire against your 2021 Chrysler 300, and it updates tire diameter when you change rim diameter. Use it to visualize clearance, poke, and overall diameter changes before you buy.

• Step 1 - Identify your OEM baseline. Enter the exact wheel width, diameter, and offset plus the stock tire size currently on your vehicle. If your car has 17 in tires, enter that 17 in setup. If it has 18 in wheels, enter the 18x7.5 ET24 and the matching OEM tire size for that wheel. If you are not sure, verify with the owner manual, door-jamb placard, or dealer.
• Step 2 - Enter the donor vehicle or custom wheel. In the Donor section, input the wheel diameter, width, and offset you are considering. If you change rim diameter, also input a tire size so the tool can calculate overall diameter and speedometer change.
• Step 3 - Review clearance changes. The tool reports inner clearance to the strut and outer poke to the fender. A larger positive offset moves the wheel inward. A wider wheel adds width half to the inside and half to the outside if offset stays the same.
• Step 4 - Keep total tire diameter reasonable. Aim to keep overall diameter within about 3 percent of your OEM baseline to minimize speedometer error and prevent rubbing. The calculator shows the percent change as you adjust sizes.
• Step 5 - Validate with measurements. After you like what the calculator shows, measure your car: brake caliper clearance, strut clearance, fender lip, and liner at full lock and compression.

Fitment Checklist Before You Buy

• Bolt pattern - Must be 5x115. Do not attempt to fit 5x114.3 without properly engineered adapters.
• Center bore - Vehicle hub is 71.5 mm. If your aftermarket wheel has a larger bore, use 71.5 hub-centric rings sized to that wheel. If it is smaller, the wheel will not seat.
• Offset and backspacing - OEM example is ET 24 mm with about 4.69 in backspacing on a 7.5 in wheel. Moving to higher ET increases inner interference risk. Lower ET increases poke and fender rub risk.
• Brake clearance - Some trims can have larger front calipers. Test fit the bare wheel to ensure spoke and barrel clearance.
• Suspension and body - Check inner strut clearance at the spring perch, and outer fender and liner at full lock and compression.
• Load rating - Wheel and tire load index must meet or exceed OEM ratings for the Chrysler 300.
• TPMS - The 2021 Chrysler 300 uses TPMS. Plan to transfer or replace sensors and program them as required.
• Lug nuts and seat type - Thread is M14x1.5. Match the lug seat style to the wheel manufacturer specification. Do not mix conical, ball, or mag seats.
• Speedometer and ABS - Keep overall tire diameter close to stock to maintain correct speedometer and driver aid behavior.

Plus Sizing And Common Upgrades

Plus sizing means increasing wheel diameter while selecting a tire with a lower sidewall so overall diameter stays similar. Because OEM setups vary on the 2021 Chrysler 300, always start from your verified baseline.

• From a 17 in baseline like 215/65R17 - The overall diameter is your reference. Use the calculator to find 18 or 19 in tire sizes that keep overall diameter within about 3 percent and maintain sufficient load index.
• From an 18x7.5 ET24 baseline - If keeping the 18 in diameter but changing width or offset, simulate inner clearance and outer poke. For diameter changes, select matching tire profiles to keep overall diameter close.
• Wider stance - Increasing wheel width without changing offset pushes half the added width inward and half outward. If you also reduce offset, the wheel pokes out more. Use the calculator to see both effects.
• Ride and handling - Larger diameter wheels with lower-profile tires can sharpen steering feel but may reduce ride comfort and increase impact risk. Choose quality tires and maintain proper pressures.

Tip: Record your OEM tire’s overall diameter from the calculator. While exploring plus sizes, target new options within roughly ±3 percent of that value and verify clearances on the car.

Installation Tips

• Safety first - Park on level ground, use wheel chocks, and support the car with jack stands under approved lift points.
• Clean mounting surfaces - Remove rust and debris from the hub face and wheel mounting pad for true seating.
• Hub-centric rings - If your wheel center bore is larger than 71.5 mm, install proper rings before mounting.
• Lug nuts - Hand start all M14x1.5 lugs to avoid cross-threading. Tighten in a star pattern.
• Torque - Use a calibrated torque wrench and tighten to the OEM torque specification from your owner manual. Recheck torque after 50 to 100 miles.
• TPMS - Transfer or install sensors and perform relearn or programming as required for the 2021 Chrysler 300.
• Final check - Spin each wheel by hand to confirm no contact with calipers, knuckles, or liners before driving.

Tools And Helpful Supplies

• 1/2 inch drive torque wrench
• M14x1.5 lug nuts or locks matched to your wheel seat
• 71.5 mm hub-centric rings
• Wheel chocks

FAQs

• What is the bolt pattern on the 2021 Chrysler 300

  The supplied OEM bolt pattern is 5x115.

• What center bore do I need for hub-centric fitment

  The vehicle hub bore is 71.5 mm. Aftermarket wheels with a larger bore should use 71.5 hub-centric rings sized to the wheel. Wheels with a smaller bore will not fit.

• What lug nut thread size does it use

  M14 x 1.5. Match the lug seat style to the wheel manufacturer’s design. Do not mix seat types.

• Will 5x114.3 wheels fit my Chrysler 300

  No. 5x114.3 is different from 5x115. Do not attempt to force-fit. If adapters are considered, they must be engineered for the vehicle, hub-centric 71.5 mm, and maintain proper offset and thread engagement. Use at your own risk and verify legally and mechanically.

• What offset should I choose for aftermarket wheels

  An OEM example is ET 24 mm on a 7.5 in wheel. Changing offset affects inner clearance and outer poke. Use the calculator with your exact baseline and measure your brake and fender clearances before purchase.

• My tire says 215/65R17 but I see an 18 in wheel listed. Which is correct

  Both sizes can exist on different OEM configurations. Trust what is on your specific vehicle and verify by VIN with a Chrysler dealer or the owner manual, then use that as the baseline in the calculator.

• Do I need new TPMS sensors

  If reusing OEM wheels and tires, you can typically retain the sensors. For new wheels or a second set, plan to install compatible sensors and perform the vehicle’s relearn or programming procedure.

• How close should my new tire diameter be to stock

  Keep overall diameter as close as practical to your OEM baseline. A common guideline is within about 3 percent. Use the calculator to preview speedometer change and clearance impacts.
