If you have stock 16" rims with 28" bias ply or 30" radials, and don't like how the engine struggles in first gear with the 3.55 gears, you can dial it in for more acceptable driveability by going to 15" with less than 28" tall tires (as HRL suggested).
I had to do just the opposite with a 235 with a 4.64 rear gears, 28" tires, and a T-5 transmission.
That combination made 1st gear an almost useless granny gear. I went to taller 30.5" radial tires and that dialed everything back in. It made 1st gear very useable and it also resulted in the ability of going 70MPH without the engine screaming in 5th gear.
