I own a 2014 Honda Accord Coupe ex-l 3.5L v-6 and put on a set of 25mm wheel spacers on the rear and the sides are not even. My passanger side wheel comes out farther than my driver side. I jacked back up and removed wheels and checked spacers and everything looks normal. Drives fine but have no idea why one looks so much bigger.

That is strange... Are they factory wheels?

 

tires aren't even the same size. Was it that hard to realize that, OP?

 

Now that I look closely, you're right- it looks like one is wider than the other....

OP, did you check the tire sizes?

 

What are your wheels specs? Did you roll your fenders? Don't you experience any rubbing with 25mm added? Are you going to go wider with the front?
