35s and what gears?

i know i cant go any bigger than 4.88s in the front.
i have 4.10s now. i want to run either 4.56 or 4.88 but i want the same final ratio as i had with stock 30.8(somewhere in there) and 4.10s.

i pull a trailer and its usually pretty heavy.. 3.5k lbs or more. yet at the same time i go on long trips and drive some highway. i have 53K miles and counting.

so im a little concered about gas mileage... but at the same time i think if i regear... i should still get respectable gas mileage.



this is out in the dark something ive never really understood... but if i can create the same final drive ratio as with stock setup wouldnt i get simular gas mileage?


idk im just looking for opinions..

Isn't there a way to calculate what gears you shold come up with? I remember reading about it somewhere but I can't for the life of me think where right now. I'll look around for it. I'd say go with 4.56 though. Something about 4.88 just seems pretty extreme to me.

(new size / old size) x current ratio= projected ratio. then round to nearest size.


IE (35/31)x4.10=4.6290. nearest ratio, 4.56...

With your auto tranny 4.56's should be plenty. I have a hard time getting it rolling from a stop at the bottom of a hill and with a load. You would have an easier time with your auto tranny. So with my stick shift and me planning on towing often I am going for 4.88's. Really I think if I had an auto tranny and was not going to tow often I think 4.10s would be plenty with a 4.0L.

As Gil pointed out, the 4.56's with the 35's will bring your engine RPMs at any given speed back to near stock. However, your fuel economy will be noticeably reduced by the aero and rolling drag of the larger/wider tires and by their extra weight. The lift is a negative, too.

but at the same time wont it help out my acceleration which will allow the engine to work a lot less, and would help gas milage, or is this just something that i think would work but its not. lol
