Forgive me guys but i don't have a lot of time to research this and i thought someone here could give me a quick answer. The car is my son's( just picked up 2 weeks ago-- we've been looking at CT's for a while and he finally found one to pull the trigger on) and he is in Vermont for the weekend and not available but had indicated that he wanted snows for the winter. I found a set but am not sure if they will fit. They are 235/45/17s. I went to look at them nut did not check the offset. They are original Toyota/Lexus rims and came off a IS 250.I messaged the seller to check the offset but , as yet, haven't heard back. Any help is appreciated.
