35" tires with 8-speed & 3.21 gear ratio - is this a horrible idea? One shop said it has enough low end torque and will drop down to low rpms (ideal situation) on the highway so they said go for it. Wanted to get your opinions on this.

Thanks!

Highway will be good! City will be a little worse

Since you have an 8 speed I say go for it. I have a 4.7 with 3.55's and a 6 speed and I run 35's with no issues at all. Not near as bad of a power loss as I was expecting. Dropped about 2 mpg average going from 31.5's to the 35's.

do the math using the 8 speed tranny ratios. I think it will be fine. People without the 8 speed tranny are thinking old school.

Thanks for the replies. Rizzkid12 - can you shed some light on where I can learn more about "the math" regarding the ratios? Thanks!
