No, tigers are chordates - phylum Chordata, a different phylum than Arthropoda (the arthropods). Pretty much anything with an internal skeleton and backbone like mammals, birds, reptiles, amphibians, will be chordates. Arthropods have their skeleton on the outside (exoskeleton), like the insects or crustaceans.
The exoskeleton (carapace) is made mainly of chitin, also a component of our hair and nails!
