I have 245 35 19s now and want a little more side wall.

Correct me if I’m wrong but the (235) is the width tire, (35) is a ratio to make the sidewall height? So if you want more sidewall you should go to a 40.

you are right.

Why would you want to go to a narrower and taller tire on a 19?

I have PSS coil overs and they get tighter if i raise them so if i go a little narrower an a little taller i was hoping for a smother ride.

im running 235/35/19's on my 19X10 front and im dropped on bilstein PSS9's

what's the ride like for you? and where do you have the shock set at? you don't look slammed just a nice stance.

the springs have 20 threds left and im all the way stiff on 1, on hard bumps the shock bottoms out a bit. I will have to lift the car up a bit and put it to 2 just for a more comfortable ride
