Default Tire height for 1/4 mile. How big can I go?

Ok, currently running 28 inch drags, and have ran 325 50 15 drag radials as well. Car has fully adjustable suspension, and stock ride height. It has also been "cut, hammered, and beat" to fit the 325 50 15s.
I plan on running the 1/4 mile but by my math, I am going to be turning her hard due tot he 3.73 gears and no o/d.
What is the biggest (Tallest) tire folks have installed without having to do anything extreme? (15 inch wheel, non narrowed rear end)

I don't believe you can fit more that a 28" tire without trimming the lower wheel wells. I run 28x10.5 ET Drags and it's very close to the front lower wheel opening and rubbing the bumper a little.

28'' without some trimming. I had 4.10 gears with a 28'' tire at one point and I let it rub the rear part where the bumper cover turns into the wheel well to clearance itself. I have gone back to a smaller tire and 3.42 gears and was going through traps right around 6100 last season.

The 28 is about as tall as you are gonna get, you "might" be able to get away with teh 295/60 radial that is 30 inches tall, but the bumper cover is gonna need come cutting for sure.

Better bet would be to just change the rear geat to a 3.55 and then not have to worry about it.

Probably make it easier to leave on more power and be faster too.
