Fender Design - Wheel Arch Challenge

Wheel arch gap: As per European law there must be atleast 10 mm gap between fender arch and tyre at given 5 points so that pedestrian will be safe from chipping (of small stone and mud) also car body. Below is image of wheel arch.

Steps to find gap:

with the help of sketch draw lines in 30 deg, 50 deg from center vertical line also from 150 mm above from horizontal line as per European standards. Then mark those points on fender arch with help of point, now further project those points SB, SA, SC SD, SE vertically on same level as shown in image attached below.

Now project tangent line on tyre outer circumference and sketch parallel line (to the tangent line) vertically upward to same level as done for arch point as shown in image.

From the top view measure the distance between fender arch and tyre for all points SB, SA, SC, SD, SE as shown in image.

So as we can see there's 10.0002 mm at each point so fender design passes European standard.
