  • Why don't we show the price?

    When a manufacturer implements a Minimum Advertised Price (MAP) policy, they create limits on the list price that retailers are allowed to advertise their products for. In line with our efforts to continually provide the lowest possible price, we've made it easier for you to inquire about our Exclusive Pricing on these MAP items.

  • Shipping Policy

    Free Ground Shipping
    Free FedEx ground shipping on all orders over $100. Free shipping to 48 Continental United States only. Orders under $100 will incur a FedEx ground shipping charge of $9.95.

    $9.95 Per Wheel/$25 Per Tire
    Each wheel will incur a $9.95 per wheel fee and each tire will incur a $25 per tire fee up to $129. You will be charged a maximum of $129 regardless of how many wheels and/or tires you purchase.

    $129 Truck Freight
    Oversized parts will incur a $129 truck freight charge that FedEx cannot provide standard ground shipping on.
