yeh front will be close to the UCA, bloody close, generally i say 235/45 with a +30 offset is the furthest in id go, 225/45 will protrude 5mm less in, and about 4mm lower, but u have 8mm more offset pulling the tyre in further. so it will definitely be close, and probably come down to the tyre model and individual car as to whether it actually scrubs or not, but nothing a spacer a few mm thick cant fix.
my bet is that it will clear, but no guarantees on that one.
