Hi, I would like to buy new rims on which the tyre sizes 205/45R17 215/45R17 225/45R17 are allowed. The 225er costs about 10€ less per tire, but in the report I have to produce the conditions K1c The wheel cover on axle 1 is to be produced by exhibiting the front apron and the fender or by mounting permanently fixed body parts in the range 30° before to 50° behind wheel center. The dimensions of the tyre (1.04 times the nominal width of the tyre) are covered in the above mentioned area. K2b The wheel cover on axle 2 is to be manufactured by exhibiting the rear apron and fender or by mounting permanently fixed body parts in the range 0° to 50° behind the centre of the wheel. The entire width of the wheel/tire combination must be, taking into account the maximum possible operating dimensions of the tyre (1.04 times the nominal width of the tyre), in the above mentioned Bereic K6g On axle 2, the fixing flap of the rear apron is to be shortened by 5 mm at the transition to the wheelhouse cut-out edge or to bend the same measure to the rear/top. K8c On axle 2, the wheelhouse cut-out edges are to be widened by 5 mm in the range 200 mm before to 100 mm behind wheel centre. Therefore, my question, pay off the 40€ less or make K6g and K8c (K1c and K2b must always) more problems. Thanks for the answers (and sorry for the long post).
