Cadillac ELR Spare Tire Sizes
The Cadillac ELR has used a 5x115mm bolt pattern for all models from 2014 to 2016 along with a tire diameter of 27.7" 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 Cadillac ELR spare tire selections. In this case, a 145/60R20 temporary spare tire is the recommendation for all applications.
