What size tires do I need for a 2008 Ford Taurus?

The correct tire size depends on the exact Taurus model and wheel package you have. For the 2008 Taurus lineup, the Taurus X crossover was the model offered that year, and tire sizes typically fall around 17-inch or 18-inch wheel options. The safest approach is to check the driver’s door placard or the owner’s manual for the precise OEM size for your vehicle, since trims and optional wheels varied.

In this article, you’ll learn how to confirm the right size for your car, what sizes are commonly found on that year, and practical guidance for replacing tires. We’ll cover where to look for the official size, how to interpret the sidewall codes, and important considerations when selecting replacements.

How to confirm the correct tire size

To be certain of the exact size for your 2008 Taurus, start with the vehicle’s official documentation and markings on the car itself. Tire size is standardized and printed on the door jamb placard, the tire sidewall, and in the owner’s manual. The VIN can also be used by a Ford dealer or tire shop to pull up the exact OEM specification for your vehicle’s trim and wheel package.

Where to find the official size on your vehicle

Look on the driver’s door jamb placard for a line labeled “TIRE SIZE.” It will show the front and rear recommended sizes. If the placard is missing or unreadable, check the owner’s manual or contact a Ford dealer with your VIN to confirm the exact size and the correct load/speed ratings.

Understanding the sidewall code

A typical tire size code might read as P235/65R17 or P245/60R18. The first number (235 or 245) is the tire width in millimeters. The second number (65 or 60) is the aspect ratio (the height of the sidewall as a percentage of the width). The “R” denotes radial construction, and the last number (17 or 18) is the wheel diameter in inches. Always match both the diameter and the overall rolling circumference to maintain accurate speedometer readings and traction control function.

Common tire sizes you may see for the 2008 Taurus X

Below are sizes commonly associated with 2008 Taurus X models depending on wheel size. Use the placard in your vehicle to confirm the exact OEM size for your trim and wheel combination.

• P235/65R17 — fits vehicles with 17-inch wheels (a common base/mid-trim configuration)


• P245/60R18 — fits vehicles with 18-inch wheels (typical on higher trims or premium wheels)

These sizes reflect typical factory configurations for the 2008 Taurus X, but there were variations based on options and regional specifications. Always verify with your vehicle’s documentation or a Ford dealer using your VIN.

Replacement and compatibility tips

When replacing tires on a 2008 Taurus, it’s important to choose a size that matches the OEM diameter and to consider the tire’s type, load rating, and speed rating. If you replace only two tires, or switch to a different size, you may affect the car’s handling, ABS functioning, and speedometer accuracy. The goal is to maintain even tread wear and consistent performance across all four corners.

• Always use tires that match the OEM diameter to keep speedometer, traction control, and ABS systems accurate. If you choose a different size, you may need a recalibration or reprogramming in some cases.


• Prefer replacing tires in sets of four to maintain balanced handling and traction. If you must mix tires, do so only with carefully matched sizes and tread types as recommended by a tire professional.


• Check the load index and speed rating on the door placard or owner’s manual. Choose tires that meet or exceed the OEM ratings suitable for your vehicle’s weight and typical driving conditions.


• Consider climate and driving conditions when selecting tires (all-season, winter, or performance tires). The Taurus X’s use case may influence your choice beyond just size.


• Inspect tread depth and tire age. Tires older than 6–10 years should be replaced regardless of tread, and always ensure proper mounting and balancing by a professional.

By aligning your replacement choices with the OEM size and the driving needs of your Taurus, you’ll preserve intended handling, safety, and fuel efficiency.

Summary

To determine the right tires for a 2008 Ford Taurus (primarily the Taurus X that year), locate the exact OEM size on the door placard or in the owner’s manual and confirm with your VIN if needed. Common sizes for 17-inch and 18-inch wheels are typically around P235/65R17 and P245/60R18, respectively, but variations exist based on trim and options. Always match diameter, load rating, and speed rating, and consider replacing all four tires to maintain balanced handling and safety.
