I have some 18x10 and 18x12 wheels, and wondering what tire size is needed for them. I am guessing 275/40/18 for the front, but for the back I have no idea. Pictures would be great!

275 on the front might not be wide enough. 285 maybe.

if you were to put a 275 on the front i would do i 35 series and not a 40. I have seen 275/40/18s on the front of F-cars and they just look too meaty.

I am just not a fan when i see cars with thicker sidewalls on the front than the back

neither am I... So a 35 series would have a smaller side wall.

275/35/18

First number is treadwidth in millimeters
Second is sidewall height as a percentage of treadwidth
Thrid is wheel diameter in inches

For a 18" x 10" wheel 285/35/18(25.85") minimum, a 295/35/18(26.13") would be perfect!

A 335/30/18 is 25.91", and a 345/30/18 is 26.15" tall

For the best look keep the front tire height equal to, or shorter than the rear tire height.

I guess the bigger question is do they fit the car? . . .

295/35/18 fronts and 345/30/18 rears. would look great. I dont see how you are gonna fit it on a 4th gen but, It all depends on offset, shortened rear, etc...
