Default Changing wheel size

Anyone know what size tires to go with to give the factory height when changing to 18" rims? I have a 90 with the factory P275/40/17.
I would like to go to 18" in the front with the factory height/width and want to go with 18" in the rear with the 315/35/17 look only on 18". I have been to a few tire shops and have got a few different answers, go figure. Thanks for the help...

You can go 275/40ZR18 all around. I've seen a 90 with C6 wheels. It looked Ok.

What you want to do is go on the Tire Racks site,pull up a brand of tire and pull up specs.

You can go 275/35/18 up front and 315/30/18 out back. These are the closest you're going to come to matching the 17s overall diameter. You can also do a 295/35/18 out back, but obviously it wont be as wide.
