    Wheel Bolt Pattern and Set Back

    Morning All,

    I have Z9 with the custom American Racing wheel upgrades, those chrome Torq Thrust II I believe. Looking to change them to a smaller diameter wheel as two wheels are bent and I've already replaced one that was destroyed on highway (pot hole on I71). Looking for options as I don't want to keep replacing these rims at $200+, looking to see what will fit the trailer and explore changing out all 5 wheels/tires. These seem too soft of a wheel for a boat trailer, ideally if I can find a more rigid 17" option that will take the existing tires, that would be fantastic as the tires are new.

    The wheel bolt pattern is 5x4.5" (5x114.3mm). I'm running the upgraded 18" wheels on mine and they are 18x9 +10mm offset. Haven't had any issues with bent wheels though.
