275/35/18 & 295/40/18 RT-615K on 68-72 A body

[Zanie]

Is anybody running this combination?
275/35/18 & 295/40/18
I’m looking to move up from my current 17s & stuff the wheel wells of my 71 Chevelle convertible.

I plan to run the 275/35/18s on a 9 inch in the front.
Ultimately I’d like to run 305/35R18 on a 10 inch in the rear (like musclecarjohn), but I can only find them in a drag radial.
I generally put 2500+ miles on my car so getting caught in the rain is unavoidable, so I’d rather not get a drag radial.
I’d like to run the Falken Azenis RT-615K because of the 200 treadwear.
I’m a little worried about the drastic difference in sidewall height with the 275/35/18 & 295/40/18

Falken makes a 315/30/18, but it’s just too short for my wheel well.



Does anybody make a 305/35R18 that’s not a drag radial?

I saw R Linke had 275/35/18 & 295/40/18 on his 70 Chevelle project, but it’s hard to get a feel for it without the body on the frame.
Any input would be great.
Thanks!
