    Power loss on my 2.7 4x4 2010 model is noticable on 32s.. I just regeared and the power greatly increased. 4.88 gears are a must. I have CAI, headers, catback exhaust, but the gears give it way more power than anything else.

    Larger tires will always result in power loss and mileage loss. You can't beat physics. Whether or not it's "too much" is up to you.

    Personally, I felt my 2nd gen was overly peppy at the stock wheel size. With 33s it feels just right to me.

    tc, power loss was not too bad until u go offroad rock crawlin or go up some steep hills (like up to tahoe throught the Sierras gotta down shift qhite a bit). It bogs down in mud and snow quite a bit too with 32s.

    Daystar 2.5" looks great. It rides a little stiff and doesnt flex too great tho. I got 2" block in rear.

    4.88 with 32's :eek:

    That puts you at roughly 2905 RPM at 70 MPH. For 32's I think 4.88 are very excessive! Maybe a 4.30 and 4.56 tops.

    70 MPH .81 Overdrive ratio
    4.10 ~ 2440
    4.30 ~ 2560
    4.56 ~ 2715

    Mind you as well I input 32" not what 265/75/16 usually measure out to which is about 31.5-32ish. Its also not just the diameter difference that you lose mileage and power on its the width as well. The wider the more friction which means more power needed which results in more fuel used.

    ya im just below 3K on the RPMs at 70mph with the 4.88s. Not too bad since I dont do a whole lot of highway miles - and when I do, it is fine. I'm glad I didnt go with anything less than 4.88s - it wouldnt have been worth it. Plus my next set of tires are gonna be atleast 33s so that'll help too.

    x2 on the excessive gearing!

    I'll be sticking with 265's rather than going to 285's for mpg purposes.

    265/75 16 worked great for me. A little power loss but not much. Same with fuel economy.
