Tallest tire fitment on rear of Scamp

As you can see I barely have 1/8th inch on either side of the tire but I should be able to clearance the fender lip and trim a little bit. In the pictures above the car is sitting about an inch higher than it needs to because the 275/60-15 is about an inch higher than my current 245/40-18's So once everthing is mounted I can lower the car onto the tire and tuck about another inch into the fender well behind the skirt below are pictures of my current 245/40-18 and the clearance differences compared to the 275/60-15 above.
