Selecting the correct 2015 Chrysler 200 tire size keeps your sedan handling predictably, braking safely, and riding smoothly. Factory engineers designed the suspension of this midsize car around specific dimensions, load ratings, and speed indexes. If you install rubber that deviates too far from these benchmarks, you'll notice accelerated tread wear, altered speedometer readings, and a harsher ride quality.
Whether you're replacing worn-out touring rubber or searching for an alternative seasonal setup, this guide covers exact factory specs, safe aftermarket tolerances, and essential maintenance steps.
Factory Tire Sizes and Trim Levels
Chrysler offered the 2015 model with two primary factory wheel diameters depending on whether your car rolled off the line as an LX, Limited, 200S, or 200C. The base and mid-level configurations typically featured 17-inch wheels, while sportier trims received larger 18-inch alloys. A rare 19-inch package was also available on specific appearance-group trims.
- 17-Inch Wheels: The standard factory size is P225/50R17. This configuration prioritizes ride comfort, impact absorption over rough potholes, and balanced fuel economy.
- 18-Inch Wheels: Sportier trims utilize P225/45R18 tires. The lower profile reduces sidewall flex, sharpening steering response during cornering.
- 19-Inch Wheels: Select models equipped with the factory sport suspension run P235/40R19 tires, offering maximum lateral grip at the expense of a firmer ride.
Sticking to these factory dimensions ensures your anti-lock brakes, electronic stability control, and traction systems function precisely as intended by the manufacturer. Observers at Bloomberg have shared their thoughts on this matter.
Decoding the Sidewall Data
Understanding what is printed on the side of your tire helps prevent costly purchasing mistakes. Every standard tire code follows a structured format that communicates its physical dimensions and construction type.
Take the common factory size P225/50R17 as an example:
- P: Stands for Passenger, indicating the tire is engineered for passenger cars rather than heavy-duty light trucks.
- 225: Represents the nominal section width in millimeters, measured from sidewall to sidewall at the widest point.
- 50: The aspect ratio, showing that the sidewall height is 50% of the tire's total section width.
- R: Designates Radial internal construction, where fabric cords run perpendicular to the bead, improving tread life and high-speed stability.
- 17: Specifies the wheel rim diameter in inches that the tire is designed to mount onto safely.
Load Index and Speed Rating Requirements
Beyond physical dimensions, replacement tires must support the weight and performance capabilities of the vehicle. You will find these two characters—such as 91V or 94W—printed immediately after the main size string.
- Load Index: A numeric code representing maximum weight capacity per tire at maximum safe inflation pressure. A rating of 91 supports up to 1,356 pounds, while a 94 rating handles 1,477 pounds. Always match or exceed the factory load index. Dropping below the original rating risks structural failure under heavy loads.
- Speed Rating: A letter code indicating the maximum sustainable speed. Most 2015 models came with V-rated tires (safe up to 149 mph), while sportier trims featured W-rated rubber (up to 168 mph). Never install tires with a lower speed rating than factory specifications.
For official tire safety standards and federal compliance guidelines, consult the National Highway Traffic Safety Administration.
Aftermarket Upsizing and Tolerances
Many owners consider switching to wider tires or larger wheels for a more aggressive stance. However, altering dimensions requires careful math to avoid mechanical interference.
When calculating alternative sizes, keep the overall outer diameter within a 3% variance of the original factory height. If your new setup exceeds this threshold, your speedometer will display incorrect speeds, and your transmission shift points can become erratic.
Furthermore, check inner wheel well clearance. Installing overly wide tires on stock rims can cause the rubber to rub against the MacPherson strut housing up front or the inner fender liner during tight turns and suspension compression.
Seasonal Tire Selection
Your local climate dictates which rubber compound performs best. Driving on summer tires in freezing temperatures leads to dangerous loss of traction, while winter tires wear rapidly on scorching summer asphalt.
- All-Season Touring: Ideal for temperate climates. They provide quiet operation, reliable wet-weather braking, and long tread life, typically lasting between 50,000 to 60,000 miles.
- Dedicated Winter Tires: Recommended if you regularly navigate unplowed roads or temperatures below 45 degrees Fahrenheit. Soft rubber compounds and aggressive sipes bite into snow and ice far better than standard all-seasons.
- High-Performance Summer Tires: Best suited for warm environments, offering sticky rubber compounds that maximize cornering grip on dry and wet pavement.

Maintenance and Longevity Best Practices
Maximizing the lifespan of your tires requires consistent upkeep and disciplined driving habits.
- Maintain Correct Air Pressure: Check your tire pressure monthly using a reliable gauge. The correct cold inflation pressure for your specific build is listed on the placard located on the driver-side door jamb. Under-inflated tires generate excessive heat and wear out outer shoulders quickly.
- Rotate Every 6,000 Miles: Front-wheel-drive sedans wear front tires much faster due to steering and power delivery duties. Regular rotation evens out wear patterns across all four corners.
- Inspect Tread Depth: Use a tread depth gauge or the traditional penny test. Replace your tires immediately when tread depth drops to 2/32 of an inch to prevent hydroplaning during heavy rain.
Frequently Asked Questions
Can I put different tire sizes on the front and rear?
No. The 2015 Chrysler 200 is a front-wheel-drive vehicle that relies on a uniform square tire setup. Mixing sizes front-to-back disrupts the anti-lock braking system and electronic stability control sensors.
What is the correct tire pressure for a 2015 Chrysler 200?
Most factory setups require 35 PSI for both front and rear tires under cold conditions. Always verify the exact number printed on your driver’s door placard, as door specs vary depending on factory wheel size options.
Will 18-inch wheels fit on a model that came with 17-inch wheels?
Yes, you can swap wheel sizes provided you adjust the tire profile accordingly. For example, moving from a 17-inch wheel to an 18-inch wheel requires dropping your aspect ratio from 50 to 45 to keep the overall wheel diameter nearly identical.
How often should I balance and align my tires?
Get a wheel alignment whenever you notice uneven tread wear, a steering wheel that pulls to one side, or after hitting a severe pothole. Balance your tires whenever you purchase replacements or if you feel steering wheel vibrations at highway speeds.
