Toyota Crown Signia Spare Tires
The Toyota Crown Signia used a 5x4.5" (5x114.3 mm) bolt pattern for all models from 2025 to 2025 along with tire diameters ranging from 28.7" to 29.3" tall. Using a temporary compact spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicles with larger brake calipers and anti-lock brakes or traction control systems.

In this case, a 155/85R18 temporary spare tire is the recommendation for all applications.
