Tire Size by VIN Lookup
Enter your 17-character Vehicle Identification Number to find the exact factory tire specs for your car.
Quick Answer
By entering a 2019 Ford F-150 XLT VIN, the lookup confirms the factory original tire size is 275/65R18 with a load index of 116 and a speed rating of T. The required factory tire pressure is 35 PSI.
Tire size is not stored in the VIN. Your exact OEM tire spec is on the door jamb sticker. The VIN tells you the vehicle model year and manufacturer — use that to look up tire specs in your owner's manual.
Where to Find Your Vehicle's VIN
| Location | Description | Accessibility |
|---|---|---|
| Driver's Dashboard | Bottom corner of windshield on driver's side | Easiest — visible from outside |
| Driver's Door Jamb | Printed on the tire and loading information placard | Easy — open door |
| Vehicle Registration | Official state or provincial registration document | Very reliable |
| Insurance Card | Your proof of insurance paper or digital copy | Very reliable |
| Engine Block | Stamped on the front of the engine block | Difficult |
How VIN Decoding Works
A 17-character VIN is divided into three sections: the World Manufacturer Identifier (characters 1–3), the Vehicle Descriptor Section (characters 4–9), and the Vehicle Identifier Section (characters 10–17). Character 10 encodes the model year, and character 11 encodes the assembly plant. Together, these identify the exact build configuration — including the tire package — for your specific vehicle.
