Key Features
- This listing is the 225/45ZR17 size with a 94W load and speed rating in Extra Load construction.
- The UTQG rating reflects a treadwear score of 200 along with the highest available traction (AA) and temperature (A) grades, indicating a tire tuned for maximum grip rather than long tread life.
- XL stands for Extra Load, meaning the tire is built with reinforced construction to carry a higher maximum load than a standard load tire of the same size.
- This size carries a W speed rating along with a 94 load index in Extra Load construction.
- In the 225/45ZR17 94W XL size, it pairs an aggressive directional tread pattern with a reinforced internal casing to deliver strong dry handling, traction, and high speed stability for classic and modern sports cars.
- Toyo specifically engineers the Proxes Sport R for motorsports use including autocross, time attack, endurance racing, and HPDE, and it meets the 7/32 inch tread depth specification required for many competitive racing classes.

Frequently Asked Questions
How do I confirm Toyo 178310 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 178310 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 178310?
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.
