Last updated: July 2026
| Trim | Tire size | Pressure (cold) |
|---|---|---|
| LE / XLE | 235/60R17 | 36 psi |
| XSE / Limited / Platinum | 235/55R18 | 36 psi |
These are the factory-approved sizes for the 4th gen (hybrid only) Sienna. The size on your specific vehicle is printed on the driver's door-jamb placard — trims within the same year can wear different wheels, so match by trim, not just year. Reading the size: in 265/70R16, 265 is the tread width in millimeters, 70 is the sidewall height as a percentage of that width, R means radial construction, and 16 is the wheel diameter in inches.
