265/35/18 or 275/35/18

I purchased Zo6 18x9.5 replica wheels. What is a better size for them? 275/35 or 265/35 18’s? I am going with the eibach sportline drop. Also any pics would help. 👍

You should easily be able to fit a 275 tire on a 9.5" rim.

Re: 265/35/18 or 275/35/18

Both of those sizes are for 9.5" rims. The 275 has a slightly more appropriate diameter at 25.6", slightly taller than the 265's 25.3". Other than that, the tires will fit identically and probably look very similar too.

Sportlinies and 18" wheels and tires, the car may or may not look like it needs slightly more of a drop. For some reason, no two cars end-up looking the same with Sportlines. Some look of a nice drop, and some look like they need more. But with 18s, odds are it will look like it might need more of a drop, so the taller 275 tires might help fill some of the gap better than the 265s.

That looks good. What do you have for spacers?

I wonder if the difference in height when using the same springs has do to with the springs themselves being different or the car structure.

My Bird currently still has the V6/700R

in it and sits higher than my Camaro with Eibach Pro springs and a 350/T56 which has the same rims style as yours but in 17X9.5F & 18X10.5R
