It looks as though the tiger would win in most cases. Tigers have an advantage in terms of speed and skill, particularly on land. Polar bears are exceedingly powerful and much larger than tigers. Still, the polar bear is built to hunt and thrive in the arctic.
However, the polar bear would likely win the battle in a head-to-head fight featuring two fully grown males. Their larger mass, stronger bite force, and greater stamina would allow them to outlast the smaller, weaker tiger.
Adult polar bears have no natural predators, though walruses and wolves can kill them. Longevity in the wild is 25 to 30 years, but in captivity several polar bears have lived to more than 35 years old. Humans probably cause most polar bear deaths, by hunting and by destroying problem animals near settlements.
