Re: Seriously... 4 Cylinder Question

I also have a 4Banger, and also bought it in FL (Miami), but has since found a new home in Panama (Central America, not FL). I bought it with 31's and stock gearing, and even in FL (like stated above), I had to downshift to 4th to go up overpasses and when driving against the wind.

Then I regeared to 4.88's, and it was AWESOME with 31's; I could put it on 5th, activate the cruise control (I put one on mine), and would not need to downshift even when going up an overpass against the wind. Then I switched to 33's, and it was a little better than the 4.10 and 31's, but not great (I still have to downshift on grades and when running against the wind). If you dont mind loosing fifth, you will be fine.

Moral is, if you regear properly, it will do fine regardless of tire size. Ideally, for 33's, you'll want 5.13 (but to go any lower than 4.88, you need to change your axles, as neither the D35 nor the D30 will go any higher).
