    I'm going to have to beg to differ here. But i may be wrong haha.

    I think the height:width ratio is approaching the same idea as scrub radius but just from a different angle.

    That's because changing the height of the vehicle will subsequently change the scrub radius, which would in turn have to be corrected via wheel offset (backspacing) and wheel width resulting in widening or narrowing of the wheelbase.

    So let's say we have a ratio of 74.6:75.08 and you add a 3" lift then ideally you should be at 77.6:78.08.

    Is this right?

    The link from BBS stated: "It may not be the installation of the lift kit at all. It may be those new wheels and tires that you installed at the same time you installed the lift kit. Did you fit a wider rim with a different offset to the original specifications? If you did, then your problem may be a negative scrub radius"

    I'm not an expert here and don't want to pretend to be, I'm just a nerd that reads a lot and surfs a lot of Jeep forums. That combined with building a few Jeep has built my opinions. I've been wrong more than I've been right :D

    That said I've never read anything credible that correlates height to width. What I do read a lot is people making changes and they think they "feel" a difference, but actual testing doesn't back it up. Every change you make to your Jeep in suspension or steering is going to make it feel different, sometimes better, sometimes worse. Sometimes it might feel better but it's actually worse; like decreasing backspace and it's affect on your components. Sure it may feel a little better, but it greatly increases the wear/tear on your Jeep.

    If your Jeep is a trail only rig, who cares. Take that thing out and wheel to your heart's content. But for those of us that have to DD our Jeeps, these things are important to ride, handling and long term dependability of suspension/steering components.

    Like I said, I'm usually wrong more than I'm right :)

    Thanks @HardHat420 .
    Nice write up dude. @HardHat420 . Wish I could say I see these tires in my future. But not. My main ride every day is at highway speeds, and the little wheelin I do. Just doesn't make sense for me. But awesome write up. You sold me. :thumbsup:.

    At highway speeds this tire feels just as secure as the street tires my jk sport came with.

    Not sure why that is so but it may be due to it being a racing tire and rated at 100mph.
