Diff tires in the same/very similar sizes won't make a signficant impact on mpg.
But I notice about a 1 mpg diff from replacing my heavy RE050s with the lighter Michelin Pilot Sports. Acceleration was very slightly improved (partially from weight 2-3lbs lighter and from the slightly smaller OD of the 255-35-19 vs oem 245-40-19) )
There are much more pressing concerns about tire choice than mpg. ie. wet/dry grip, noise, braking, feel tire life etc... Those characteristics vary way more across tires than mpg will

I was wondering something similar to this post. I have the 225/245 40 19 set-up now which is OEM. I want to get the 245/35 & 255/40 set up but it's time to change out my rears even though my fronts are still look okay. Would it be okay to keep running on the 225/40 fronts but put 255/40's on the rear? How will that affect the car & driving?

so i finally got my tires replaced last saturday. i went with Falken 452s and upgraded the size up 245/35/19 (Front) and 255/40/19 (Rear) and couldn't be happier. Got them mounted, balanced and installed for 760 with tax at a shop in San Gabrial, CA.
Got a noob question for you guys.... since i have upgraded my front and rear tires to a larger size than the OEM spec, will i need an alignment done for the car? Since the tires are now larger, will that affect the camber or toe?
I'm pretty sure it doesn't, but i just wanted to ask anyways just to be safe..

So, I am looking to get Falken FK452 255/40R19s for the rear of my car.. my G35 coupe isn't lowered.. just stock height. Will I have rubbing issues?
I have Nitto Invo's on right now, but they are bald.. the fronts are at about 65%, I'll change those to Falken FK452 245/35R19s when they need replacing.
Sounds like the best size combo is 235/35R19 front and 255/40R19 rear? any advantage/disadvantage from running this size compared to the stock 225/40, 245/40 size?
