Honestly, your fronts and your rears are equally crappy so while you probably won't experience any imbalance F/R due to the tires, you could do a LOT better. Next time you replace the tires (i'd recommend replacing all 4 at once in this case), get some better rubber.

 

Those nexens are super crappy. They're like the default cheapo "performance look" tire that shops put on spinner rims for the donk crowd. The dealer I bought my S from put a pair on the front before selling the car. Swapped them for Star Specs and later RS-3's and both are good tires.

 

Honda did the same to me.

Luckily, they're not too different.

Bridgestone re750 in the front and s02 in the rear.
They also put 225 all around.

They just replaced the rears so Im guessing they assumed it was the same as the fronts.

 

i like for my fronts to be a little better tire than the rears

makes for a funner drive and allows me to overpower the rears in a way that is conducive to my enjoyment of the car

 

I had Michelin Pilot sport A/S's on the front of mine and Kumho's on the rear. Swapped them all out immediately for one brand.

 

The problem is you only have an issue when you will need the best handling. If someone pulls out in front of you and the front tires have more grip than the rears you do a 360 and hope you don't hit anything. Driving in a straight line you would never notice anything different.
If I can help with the tires when you are ready let me know.
