235/45/18 is closer only 1/2" in difference between front and rear. That should work.

What was your OEM tire setup? 18" or 19"

Im not sure tbh, got it as 3rd owner.. it had sport 18s on it when I got it..

I bought the 235/45/18 in fronts.. checked all tire calculators, 275/35/19 and 235/45/18 diameter/height are within 3% , i hope im right lol

 

Thanks buddy, you've been real helpful man. I was gonna do 255/40/18 at first but I just realized I think that would be a bit too wide for the fronts. 235/45/18 sounds good, I use to run 245/45/18 all around with my old setup.

 

I think if you check the driver's door, where the recommended air pressure are, it will tell you. The sticker will be either for the 18's, or the 19's, but not both.

Not 100% sure, but i think they "customize" those decals for the OE setup.

 

Either way, the 235/45/18 seems to be within 3% of the diameter of the 17s and 18s
