You said you want wide,,,a 45F & 40 rear will work w/30mm less width on the front & if you can find the mfg. who makes them.(example 255/45/18 & 285/40/18) & if they are the same series/35,40,45.....a 20mm width differential will work & only will be 1/2" shorter in front.
it's just harder finding wider section width tires (285,295,305,315etc..) in a 40series all season.
Michelin A/S 3+ offer's a 255/45 & 285/40,,,but not sure if that's wide enough for you & they are 27" tall...you mentioned you were lowered.

What is the biggest size I could fit in the front you seem to know a lot and I am not sure about anything I have stock 18s rims and tires I am thinking 255/45 front and 275/40 rear or will the 285/40 rear fit?
