When your tires and gears were stock, you were turning around 2000rpm @ 70 MPH in 6th right?

Wouldn't every one like to get to the same spot with the 35" tires?

Isn't 2800 - 3000rpm what you would be turning in 5th gear using stock gears?

Sorry for all the ?'s Still trying to nail down my gear choice!

It just seams like 4.88 gears humming 3000 rpm in top gear is just burning gas.

So based on the chart, 6 speed 35 tires a good daily driver would be 4.56 turning 2575 rpm. Assuming all my driving is highway and city with no off road, would this gear set be able to pull those 35's around?
