Tsuraichi

Tsuraichi means, “Matching the face position”, and it is the flat condition with no difference between two faces.

The car lovers diverted this word, and they call the Tsuraichi as the best matching of the horizontal width of the car (tire house) and the outside surface of the tire, and the Japanese people aims to finish up the car by related to this Tsuraichi.

There are two meanings in this.
① The appearance is good.
② The stability of the car increases by increasing the tire contact surface (tread) sideways.  

Then, to finish the Tsurachi, first an ear (Flap in the inner side of the fender) in the fender is folded. In Japan this is said as cutting the finger nail.

Normally this is folded using a special tool, but I do it by hitting with a hammer while preventing the paint from cracking and heating with the heater gun.
 
If you do like this, then it will get like this. 

There is another method called as stretching the tire.

This is done by combining the narrow tire with the wide tire.

By this, the outer diameter of the tire will enter the inner side diagonally, and we can get the gap with the tire house.

Hence, the tire and the body will not interfere when bounding even if you finish it like this.
A car finished by this method.

This is my AE86

It also looks like that the tire is protruding out, but if you see from the top,

 it is precisely Truraichi~~~
