Yup big difference! 33" vs 34" tires which not all setups can handle the 34" or maybe even the 33" tire (fender clearance issues).
The V10's torque peak comes at a high 3500 rpm's. Its not a low end torquer but more of a scream it to get torque motor, IMO. I call it a circle track motor lol.
The guys that are using 4.10's or 3.73's are missing a lot of easy(er) driving.
I would recommend 4.56's for 33" and larger tires. 4.88 for 35's. It is so much easier on your motor and trans to be in the right rpm range (vs under the proper rpm's).
4.10's on 33"s is OK I suppose (my previous setup).
I have 4.56's on 295/70-17 (about a 33.5" tire) and would even like 4.88's more, for the added rpm's.
I am at apprx. 2200 rpm's @ 70 mph now.
I started at 285/70-17's and 4.10's. My transmission shifted back & forth a lot when I bumped up tire size to 295/70-17 with 4.10's.
Maybe I netted a half mile per gallon increase in fuel mileage. Maybe. 10-11 mpg vs 9-10 mpg previously.
Anybody looking for fuel mileage out of a V10 van or is on a shoestring budget, is in the wrong place.
It ain't cheap.
