I'm considering mounting an extra set of wheels I have from one of my cars onto another, but I'm not sure if it's economically feasible to do so. Spare Wheels: 18x8.5 5x114.3 +38 - Flat seat lug holes. OEM Wheel size of destination car: 17x7.5 5x112 +45 As I understand it, the most popular options for this scenario include: - Wheel adapters (potentially expensive?). - Wobble bolts (Will not work with flat-seat lug holes). - Re-drilling holes (Affects wheel durability). Adapters and re-drilling seem to be my only options; are there any others that I have missed?
