Will these 17 inch tires fit my car?

Ok I have a 95' honda civic and when I bought the car the tires the previous owner put on were 205 40 17. If I were to purchase 215 45 17 from someone selling them cheap would they fit my car.

The 215-45-R17 are much larger tires, so you check your wheel wells for how much clearance you still have, but I think your pushing your luck on going even larger.

Your '95 Civic can indeed accommodate a 17 inch tire and rim package. However, the proper size tire would be 205/40-17 as the previous owner had installed. A 215/45-17 tire would be both too wide and too tall.
