My front rims are 18x10+13 with a 235/40 nankang which has no noticeable stretch since these tires seem to run on the wider side. I have a proper alignment where the front has been set to 1.2*-1.4* of negative camber, and has about a finger gap, and my rim is flush with the fender. Only fender mods is that they were rolled flat.


And by doing some simple calculations from the hub(rim mounting point) to the outer flange of the rim. Let's just call this the "front spacing" since it the exact opposite of what backspacing is,

Anyway, going by this "front spacing" measurement my rim sticks out 127mm (about 5") from the hub to the outer flange, where as your rim sits 103mm(about 4") from hub to the outer flange. So essentially my front rims stick out 1" more than your rims do, so logically you should be able to fit those rims with a 235/40 no problem or maybe even a 245/40 if you run the -1* of camber.

My "fitment" may not be what you're looking for, but the proof is in the numbers as to where your wheel should be sitting with tires on it.


pic of my fronts for reference-

the first two pics show the ride height in the front with stock wheels and tires
the other pics are showing the new wheel clearances with the car lowered

I'm sorry, did you say your car has no noticeable stretch and is flush? I guess people's definition of those two words are starting to change. You have noticeable stretch and you are way past flush to the poking side. Take a picture looking straight down and that will tell whether it is "flush" or not.

That looks great to me. If you run a 235 tire, you should be ok.

Yeah the back needs to be dropped a little more. I like the gap in the front though.

The only reason I haven't dropped the back yet is because there is some slight rubbing going on. The fenders need to be rolled just a little
