Contemplating putting the Honda Accord 2014 sport wheels on our 2.4 TSX for summer use and using the stock wheels for a winter setup. I ran them through a calculator comparison tool. The size/offset sounds like it will be OK, but I am also concerned about the weight. Weight will increase by roughly 22% according to the calculator. I am wondering how much that will hurt MPG, handling, acceleration and braking. Keeping in mind the Accord sport V6 has significantly more HP/TQ than the 2.4 TSX.

It will feel different, that's for sure. The car will definitely feel a bit more sluggish getting up to speed with the added weight. I can't comment on handling or braking, because I changed my wheel and suspension setup when my car was fairly new. Handling got much better for me because I installed coilovers, and the factory brakes are known to suck, which I'm only starting to notice now as I've put in more miles.

MPG wise I'm not too sure as this depends on weight as well as contact surface area of your new tires. It'll likely go down, but I'm guessing not by much. I'm averaging 9.7L/100km (~24 MPG), and I have 18x9.5 VMR V710s on 235/40 Hankook Ventus V12 tires, doing about 50/50 highway/city. I consider that to be fairly good considering how these wheels are pretty heavy (plus mine are 9.5" wide) and the amount of city driving I do. YMMV.

I'm definitely gonna be getting some lighter wheels next time around lol. It makes a pretty big difference in acceleration to say the least.

 

Thanks for your input. I decided to pass on the Accord sport wheels because I found a good deal on stock TSX wheels.
