    I might get a set of 38.5x14.50r15 TSL SX's for my truck. I have a 4" lift front and rear and slight trimming on the front fenders. Will I have trouble running this combo? Also what gears are recommended for a truck that sees some street? Thanks.

    Rene runs 4" of lift and 39.5s, so you can fit 38.5s with no problems.

    Yeah, ~4-5" of lift and 39.5's on 15 x 10's.

    This pic shows how much trimming I did (notice the side marker for reference). I do still run inner fenders, barely. Really the biggest help was to move the front diff forwards some. I moved mine 1.25" by redrilling the perches and spring plates.

    I run 4.56's, but have the 6.2 diesel and no overdrive. With an overdrive tranny I'd run 5.13's. Without overdrive I'd run 4.56's.

    HTH.

    ```

    How much upwar wheel travel do you guys with 4" or less have without the tires hitting anything, or is that a problem? Just seems like it wouldn't have much articulation. Any pics flexed?
