Optional & Alternate Sizes (U.S.)
If you’re exploring light plus-sizing, the following are commonly listed as “optional sizes” for this vehicle. Fitment depends on wheel width/offset and suspension clearances; speedometer variance should be kept minimal.
- 18″: 245/40R18 (common optional listing)
- 19″: 245/35R19 (common optional listing)
Important: Optional sizes are catalog suggestions. Before you buy, confirm wheel width/offset, brake clearance, fender clearance, and load/speed ratings. When in doubt, stick to the size printed on your current tire sidewall and your door-jamb label.
Real-World Tips
- Daily comfort vs. look: 18″ with 235/40 rides softer and shrugs off potholes better than 19″ with 235/35. If you commute on imperfect roads, the 18″ setup is friendlier.
- Winter driving: If you face snow/ice, many owners downsize width for winter grip (e.g., 225 section on an appropriate wheel). Match load index, and don’t exceed your brake clearance.
- TPMS & rotation: Keep pressures to door-jamb spec (front/rear may differ). Re-torque lugs to spec after ~50–100 miles when wheels/tires are installed.
- Brake/strut clearance: Aggressive offsets or wide rubber can rub inner fender liners on full lock or big bumps. Measure twice.
Where to Confirm Your Exact Size
- Driver-side door-jamb label: Shows OE size and recommended cold pressures.
- Owner’s manual: Tire info, rotation, and safety notes.
- Your current tire sidewall: The most reliable quick check before ordering.
