tire sizes for front and back

[cycler]

Hey guys I need some help here. I have a 2012 M37x. I ordered my lowering springs and will install them in about a week once they arrive. Im also thinking about getting new wheel and tires for the car. Can I go staggered and what is the largest tire width I can go for the front and back. I was thinking maybe going 275 rear and 245-255 front. Or should I go 265 rear and stick with 245 in the front?

Depends on wheel set up... A little stretch is nice with the 235 front 265 rear. Flush is nice with 245 front 285 rear. But yours is the"x" so I really don't know if staggered is the way to go?? Maybe some experts can help on here Lol!!
