I'm going to be buying a new set of wheels soon in the stated size, but I'm not sure what size tires I should get. I see people recommending 225/45/17 or 235/45/17. Also, shouldn't the tires in the front be skinnier than the ones in the back? What size should go up there? Thank you!

W00t! Something I can actually answer!!! So, the first number XXX/45/17 is the width of the tire in millimeters.
215 = 8.46457 inches
225 = 8.85827 inches
235 = 9.25197 inches

Notice how much further out those will stick out on past your rims? If you are running 7.5" rims all around, I'd go with 225/45/17. I have 236/45/17 tires on the wife G and the lip of the tire sticks out so far past the rim it looks funny. The only good thing I saw from running a tire that wide is that it is now nearly impossible for her to curb check a rim.

I currently run 215/45's up front and 225/45's on the rear of my daily driver. The 215/45 is a perfect size for a 7.5" wide wheel in the front; it has just a little side-wall stretch and looks the best on the car. The 225/45 is about as wide as you want to go on the rear. Any wider and it starts to look goofy.

Also depends on the year of the car.
88's suspension allows for different wheels

I have an 86 GT.
And thanks guys, makes sense now! I'll end up doing 215 in the front and 225 in the rear.
+ for all
