A 235/45 R18 passenger tyre has a load index of 94 (standard load) or 98 (extra load/reinforced).

A 235/45 R18 passenger tyre with a load index of 102 or 103 doesn't exist, nor is there such thing as a 235/45 R18C commercial tyre.

The correct fitment is 255/45 R18 103Y XL.

The load index (and hence load capacity) of a 245/45 R18 100Y XL or 235/45 R18 98Y XL tyre is too low.

Load index has priority over rolling circumference, in terms of safety, roadworthiness & liability.
