widest tires on 18 inch rims

hey guys, i wanted to see what the widest tire i can fit in the front with 18 inch wheels, i heard that 245/40 are the widest i can fit. if anyone has any info i would appreciate it, thanx

Depends how wide the wheel is. Most take 245. SS wheels are suppose to use 245s but I have heard and seen pictures of people putting slightly wider tires on, it causes a little rubbing when turning sharp.
