1. A wheel-hub-connection-free tire traction device comprising:
- two or more opposing tire grips, each grip including plural arms extending radially from a central brace region of the grip, each arm being configured at its distal end to extend around the perimeter of a tire and to confront the same along a tire tread confronting region of the arm and partway around the inside corner of the tire tread;
a connecting mechanism for rigidly connecting the two or more opposing grips to one another such that a perimeter of a tire is securely grippable between the plural arms, the connecting mechanism including one or more first capture members extending from or within one or another of the grips, the connecting mechanism further including one or more second capture members extending within or from the other or the one of the grips, the first and second capture members being configured to engage one another to rigidly connect the two or more opposing grips together.

Abstract
A clamshell tire traction device having two or more grip portions operatively couple-able by a fastening mechanism is described. The device grips the peripheral tread region of the tire without requiring any contact or connection with the wheel or its hub. The grips are equipped with spaced-apart radial cleat-bearing arms that extend around the tread region and toward the interior of the tire. The fastening mechanism includes a tensioning mechanism that is easily and quickly operated manually by a pivotal lever and includes a release mechanism operable by a depressible pushbutton.

16. A tire traction device comprising:
-
opposing tire brace halves collectively configurable as a tire brace, each brace half including plural arms extending radially therefrom, the arms numbered and configured and spaced apart from one another to substantially embrace the peripheral tire-tread region of a vehicle'"'"'s tire, each arm mounting an array of plural traction-promoting cleats extending outwardly therefrom for frictional engagement with a tire support surface; a fastening mechanism between the opposing brace halves, the fastening mechanism manually operable to affix the opposing brace halves together into a brace assembly, wherein the brace assembly and the plural arms extending therefrom are configured and dimensioned to grip the tire along the peripheral tire-tread region of the tire to promote traction between the tire and the tire support surface during rotation of a wheel mounting the tire without contact between the tire traction device and the wheel. - View Dependent Claims (17, 18, 19)
