What size tires are on a 1990 Dodge Dynasty?
The standard factory tire size for most 1990 Dodge Dynasty models was P195/75R14 on 14-inch wheels. Some trims and markets offered optional 15-inch wheels with wider tires. For the exact specification, check the door jamb placard or the owner's manual.
Standard tire sizes and options by wheel size
The Dynasty was built on a front-wheel-drive platform and offered both 14-inch and occasional 15-inch wheels across different trims. The sizes below reflect common factory configurations you may encounter in 1990 models:
- P195/75R14 — standard on most 14-inch wheels

Conclusion: The most widely used factory size on 14-inch wheels was P195/75R14; some 15-inch wheel configurations used 205-series tires, with exact aspect ratios varying by trim. Always verify with the door placard and the owner's manual to ensure you replace with the correct specification.
How to verify the exact size on your car
To confirm the correct tire size for your specific car, start with the most reliable source—the vehicle's tire placard and owner's manual. The placard is usually located on the driver's door jamb or the fuel filler door area. If the placard is missing or illegible, consult a Chrysler/Dodge dealer or a reputable classic-vehicle manual with your VIN.
Why tire size matters
Using the correct tire size ensures proper speedometer accuracy, ride height, braking performance, and clearance. Mismatched sizes can affect handling and ABS operation, especially on early 1990s Chrysler models that relied on specific tire dimensions for correct drivetrain calibration.
Summary
For most 1990 Dodge Dynasty models, expect P195/75R14 tires on 14-inch wheels as the standard size. Some trims or markets offered 15-inch wheels with wider tires (such as P205-series). Always verify the exact size on the door placard or in the owner's manual to ensure you replace with the correct specification.
