Best tire size to go with?

[mikewashere]

Hi guys I'm looking for recommendations on a size tire to go with. I have a set of 18x8's with +14 offset. currently lowered about 1-1.5" on lowering springs. I'm after an aggressive look, not too meaty but not too low profile.

18x8 with +14 offset? what wheels are those ? As for size 245/35/18 gives the lowest difference in rotation(-0.51%) compared to the stock size (205/65/15). Which will result in driving 80 miles/h will be around 79,6 Miles/h.
