new member's question about wheels

Hi, I am new to this forum but have been lurking on here for a few weeks. I have a quick question. I have a 1996 Mustang GT Convertible and I was wondering if I would be able to put 18x10.5 rims on the back and 18x9 rims on the front. Also would 295 tires fit the back and 275 tires fit the front without any modifications? Thanks in advance.

Someone please help me.

I know there are other topics close to this one, but my question regarded the tires scrubbing on the fender shields, does anyone know if the will clear?
