Frequently Asked Questions
How do I confirm Toyo 178330 is the correct tire?
Match the full tire size, service description, load index, speed rating, load range, rim requirements, and Toyo manufacturer part number to the vehicle and wheel requirements. A similar diameter alone does not confirm compatibility.
Is Toyo 178330 sold individually?
Yes. This listing is for one new tire unless the quantity selected in the cart states otherwise. Wheels, valve stems, sensors, mounting, balancing, and disposal service are not included.
What should be checked when installing Toyo 178330?
Have the tire installed by a qualified technician. Confirm approved rim width, directional or asymmetric orientation, load capacity, cold inflation pressure, vehicle clearance, balance, and lug torque before driving.
Installation
Professional tire mounting and balancing are required. Inspect the wheel and valve system, follow Toyo's current mounting and inflation guidance, verify orientation and bead seating, check vehicle clearance, torque the wheels to the vehicle specification, and recheck cold pressure after installation.
