Hi Omodos,
With the wheel on the ground and looking from the front of the car,the CV boot has to be streched out as in pic2.Pic 2 ,however is not the OE cv boot ,as it has more rings !Pic 1 is the OE cv boot but that pic must have been taken with the wheel "in the air"!
This is what my looks like with the wheel straight and on the ground


Your Cv boot should look the same!
Why are you using jubilee clips ,instead of the proper clips ,as shown in pic2?
If you use the proper clip on the inside of the boot (smaller diametre),it will give you more space and it wont tear your cv boot.
