According to Mark Sirota's tire_size program: Specification Sidewall Radius Diameter Circumference Revs/Mile Difference 235/45-17 4.2in 12.7in 25.3in 79.6in 796 0.0% 215/60-15 5.1in 12.6in 25.2in 79.0in 802 -0.7% So, the spare has just about the same rolling circumference as the regular tire; it should be OK. If the 15" wheel physically fits on the car (clears brakes, struts, etc.), then you are fine. -- Andrew L.
