| Post subject: | Liberty off-road stats - anyone? |
Does anyone know what the following stats are for a stock liberty with a 4x4 3.7? Max climbing grade? Max side-slope? Max water fording ability? These are advertised on the H3 commercials and websites everywhere but I can’t find it on any Jeep sites (other than the Wrangler Rubicon.) |

ill see if i cant find them for you i know as a general rule for water fording is about half way up your headlights the dealership will say about 22" or 24" i think |

I think officially the fording is 20.5" with the top mounted air box I think Side Slope is in the 37 degree area +/- 2 degrees I would bet 55 degrees +/-2 degrees incline |

Might as well include approach, departure, and breakover. However, I do not know them... |

Cool, thanks. OK, here's a question, say you are on more than a 37 degree side slope AND you have traction. Anything past that and it's rool over time? Personally, I think I've always slipped the rear before I've gotten an angle that steep but I've never done it on just rock. |

The Liberty is 20.5" @ 10mph...a bit more down at 5 mph Approach.................34.6 Break Over..............21.2 Departure.................32 This is on 235/65/17s (only a 28.9" tire) Hummer OEM is 265/75/16 (which is a 31.8") Toyota FJ A.............................34 BO...........................N/A D.............................30 265/70/17...30.7" Nissan XTerra OR A.............................33.2 BO...........................24.6 D.............................29.4 265/75/16.................31.8" Jeep Liberty on very small tires does so well because of 104.3" wheelbase and shorter overall length. Just taller tires raises all those numbers up...235/75/16......29.84" will fit on stock KJ. That is almost 1" taller than the 235/65/17 used for the measurement. |

It's basically impossible to climb a slope greater than 45 degrees as a friction coefficient of 1 (or greater than 1) is required. If you meant approach angle, that is something different, but as far as a sustained grade, I'm guessing around 60%, or 30 degrees. You're not likely to have enough traction to do better than that. |

The 5mph guideline is to keep the water from going over your hood, and thus into the intake. |

Well not in that picture(the roosts just look cool), but at the end of the video I go through the same creek early in the season when it was very high, now that was fording! (and I was 16 at the time so I was a little throttle crazy once the water went over the hood) |
