Lexus RX 300 Spare Tire Sizes
The Lexus RX 300 has used a 5x114mm (5 x 4.5") bolt pattern for all models from 1999 to 2003 along with a tire diameter of 28.4" tall. Using a temporary 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. Tire diameter as well as wheel diameter clearance have been taken into account for Lexus RX 300 spare tire selections. In this case, a 195/55R20 temporary spare tire is the recommendation for all applications.
