Getting the right tires starts with knowing your size. Use the Nexen Tire USA Tire Finder to shop by tire size, year, make, and model — and get matched to performance, all-season, winter, and touring tires built for your exact vehicle.
Every tire has a standardized size code printed on its sidewall. Once you know how to decode it, finding a replacement is straightforward.
A typical tire size looks like this: 225/65R17 102H
Here’s what each segment means:
Your tire size appears in three places:
Always cross-reference your door jamb sticker with your current tires to confirm no modifications have been made.
Installing the wrong tire size isn’t just inconvenient — it can affect your safety and vehicle performance.
Tires outside the manufacturer’s specification can throw off your vehicle’s speedometer readings, compromise braking distances, and interfere with stability control and ABS systems.
An incorrect aspect ratio or width changes the contact patch with the road, leading to uneven tread wear and reduced fuel economy over time.
Many vehicles use Tire Pressure Monitoring Systems (TPMS) calibrated to a specific tire size. Wrong sizing can trigger false warnings or disable the system entirely.
The Nexen Tire Finder lets you search three ways:
Check the sidewall of any current tire, the sticker inside your driver’s door jamb, or your vehicle owner’s manual.
It’s the sidewall height expressed as a percentage of the tire’s width. A 65 means the sidewall is 65% as tall as the tire is wide.
Minor plus-sizing is common, but always consult a local tire shop. Significant size changes can affect speedometer accuracy, TPMS function, and handling.
Yes. The speed rating indicates the maximum sustained speed the tire is designed to handle. Never install a tire with a lower speed rating than your vehicle requires.
Load index applies to passenger and light truck tires and refers to a numeric code for max weight. Load range (C, D, E) applies to heavier-duty tires and reflects ply strength.
In most cases, yes. Mixing sizes — especially on AWD or 4WD vehicles — can damage the drivetrain. Staggered fitments (wider rear tires) are factory-approved exceptions on some performance vehicles.
Use the vehicle search in the Nexen Tire Finder and select your exact year, make, model, and trim for confirmed-fit results.
“R” stands for radial construction, meaning the internal cords run perpendicular to the direction of travel. Nearly all modern consumer tires are radial.
No. Mixing tire types creates unpredictable handling, especially in emergency maneuvers. Always install matched sets — at minimum, matching pairs on the same axle.
Most manufacturers recommend replacement every 6 years regardless of tread depth, or when tread wears to 2/32″. Use the penny test or check the tread wear indicators built into the grooves.
