The tires I needed were.
215/40R18 (Front)
245/35R18 (Back)
I went to the store and they didn't have my exact sizes. So these are the tires the put on for me.
215/35R18 (Front)
255/35R18 (Back)
These tires are not run flats.
Is this going to be a problem for me. The guy at the store told me to stay away from pot holes because of the fronts are lower profile. I have these on the original rims and now I am really concerned about damaging the front rims.
Can someone please tell me if I am being paranoid or not?
Thanks a lot for your help!

In short you will be fine, but here are the differences.
The front are 0.9" or 22mm shorter, or 75mm sidewall instead of 86mm stock.... Stay away from those potholes!!!
[I actually run 17's with a 100mm sidewall because of all the potholes around by me]
The rears are very close to stock, 89mm sidewall instead of 86mm stock. also the wider profile may help you stay off the curbs and prevent wheel rash.
big difference is the front to rear diameter difference now, which is 28mm, or a 37 revolutions/mi. This won't be a real problem, but it is a difference.
What tires did you get??
