1995 cobra upgrade to 2003 cobra wheels

I just picked up a set of 2003 chrome cobra wheels with goodyear eagle f1's tire size is 275/40/zr 18 on all four wheels I have them on my 95 cobra just wondering is there anything I should look out for will they rub with added weight in the car I'm nervous to drive the car after I put them on any help would be great thanks for your time

they only rub up front when you cut the wheel real tight they touch the lower control arms but from what i'm told you will never be turning the wheel that hard when driving i'm gonna live with it i guess because the look much better thank the saleen replicas i had on there!!!!
