PROGRIP 312600 Cargo Tie Down Standard Duty Ratchet with Black Handle: Small Grip and S-Hooks, 16' x 1"

is this a pair of ratchet straps?

does this strap have zero hooks or a single hook on the ratchet side?

Could I use this to strap a tire down onto my cargo rack?

Do these have a chemical smell? I bought some from another brand that had an intense chemical smell especially in the sun.
