With the info you gave me, I can tell you that the tread width is the same between the two cars, no problem there. Very very likely the offset will be the same between the two cars, no problem there. The problem that I do see is that the Accord wheel is 1" taller than the Civic wheel. You need the tire height of your new wheel setup to be the same height as what came off of your car. Use this calculator: http://www.miata.net/garage/tirecalcold.htmlBased on my research the 17s on the Civic are 235/45/17. The Accord Sport wheels my buddy is running are 235/45/18. Considering the offsets are within the Civic's parameters, what is the potential cause of the 1 inch difference?
Obviously the ride will be slightly more rough, but aside from that ... Possible rubbing? Unnecessary stress to suspension,etc?

Generally traction control systems read wheel speed from all 4 wheels, compares them and determines if a wheel is spinning. Since all 4 wheels will be same diameter, the TCS won't know the difference.3.4% difference in diameter/circumference. That's not much difference but I wonder how sensitive the traction control system is and if it'll be affected by just 3.4% change.
For which model?Tirerack has the 2016 Civic wheel offset at +42.
I see so the LX and Touring wheels have different offsets (+42 and +45). Did you notice if Tirerack have offsets for each trim level's wheels?LX steels at +42. This looks like the same offset used on the last couple of civic generations, as well as the RSX.
And the extra 5mm offset gained from doing that would also make the wheels a bit more flush with the fenders, giving a sportier look (look how tucked the stock wheel offset is in the OP's second photo).My belief is that Civics of all the trim levels have the same offset- +42. The wheels themselves are offset +45- close enough for horseshoes.
Accord Sport wheels (and, I believe all Accord wheels from the last dozen years) are +55. The bolt pattern is the same as a Civic so they look like they should fit. If you really like the Accord Sport rims you can add spacers. A 15mm spacer would bring the offset to +40- close enough for horseshoes.
