    Default Tire spring load

    When using the Tire Pro from Boydbilt, how do you correlate that measurement to your spring load?

    How do you equate the Boyds measurement to the on-track stiffness? Is that "blow up effect' of the centrifugal force during spinning a simple preload? Or, does that tension on the nylon actually impact the on-track rate?

    I'm thinking the same people that buy this machine will be the ones complaining about not being able to afford to keep up with the big teams while Throwing money in all the wrong directions. Smh

    You are speaking my language.

    If I was manufacturing tires, I'd probably consider it. But then, I'd have something much more elaborate from MTS or Instron. For now, I'll keep looking for "build at home" ways to improve the cars until that's completely illegal.

    Is it not a device to get a little closer to consistent setups?

    Depending on tire variations batch to batch, maybe. If you can buy hundreds and sell the ones you don't think test right. I don't see many people having a legit use for this as far as bang for buck.

    I'd say the ranges in 1 single tire could be huge just depending on where you check it. The things aren't even round.

    In the test they published, on 4 tires, the spring load was 60-130 lbs difference!

    In my thinking, what kinda difference does it take for a good driver to feel!

    I change tires all the time and car doesn't go to hell.

    Take your shorter RR spring from Raceknowhow, your special matched set from the tire smasher, and I expect to see you running upfront at the World 100 this year!

    If that is all they was off, then they got a really good matched set of tires.

    Says the one who makes thinks an 8” spring gives you more sidebite lololol. But hey, when all else fails, make rearend jokes…… 👍🏻

    I'm curious what the machine says between a new tire and one with 100 laps on it, an molested one, and a sipped only one, and a cut one.
    Then I want to find a dirt track that's consistence enough from night to night, lap to lap for it to matter.
    Then I want too see Davenport or the like do an A-B-A blind testing.

    Without that, it's just marketing noise.
    Not much difference then this spring rebound/histeria theory. In the dirt modified world, lots of those guys are replacing spring every 10 nights with $150/each springs because they feel the rebound goes away but can't be tested for.
    Like tires, tires are bigger springs than the springs are.

    My question is how is compressing a tire vertically on a flat surface while stationary even remotely relevant to any condition seen on the car lol
