While Ussuri brown bear might be included in the Siberian tiger's diet, the stripped cat usually targets cubs and females. The tiger has more kills being a full time predator but the male brown bear is too strong for it.

BART SCHLEYER, SCIENTIST AND HUNTER :


"Some older tigers would also stalk and kill brown bears, which were easier to catch than elk. Following tigers with radio locators, Bart could read these stories in the snow. The tigers usually just walked the bears down from behind. The big cats had killer instincts and usually about a hundred pound weight advantage on the bears. They would go straight for the neck and sever the spine at the base of the skull. Every once in a while the trampled snow would tell of a furious fight, which always ended with a dead bear"

[Montezuma]

Brown bears usurp tigers kills as sloth bear does to leopard and black bear does to cougar. No difference.

[Gorilla king]

Despite the fact that his diet is dominated by food of plant origin, brown bear is the largest ground-based predator before the Far East. This beast is capable to obtain practically all forms of the mammals: from the mouse-like rodents to the tiger myshevidnyh.

In the far Of east are known the cases of the selection of victims by brown bear in Amur tiger and leopard. In of the Of sikhote-Alin preserve before 35% of cases of the victim of tiger they were obtained by the brown bear as a result of their selection from owners. In this case the tigers departed based on their victim entirely, or alternately divided them with the bear.

DALE MIQUELLE-TSTP DIRECTOR

"It is clear that brown bears reap greater benefit from the presence of tigers because tigers killed animals - a source of protein food for bears. Therefore, not surprisingly, bears commonly use this source, even if it requires a direct clash with the Tigers., Tigers, it seems unable to prevent adult male brown bears away from their food."

There is an addition: I believe that tigers that have learn to hunt bears are Dale or Misha who at most killed females almost their own weight.

That's correct yeah. Also, "not all brown bears win in clashes with tiger" this is a perfect example of how wording gets misinterpreted, because by "clashes" they are talking about Dale/Misha killing bears by first ambushing them, but some females were strong enough to dislodge that ambush and fight, for example that famous 20 minute battle, but that female bear was most likely already injured by that initial ambush and still was able to fight.

IF THE TIGER’S FIRST ATTACK SUCCEEDS AND THE BEAR FALLS DOWN, THE TIGER MASTERS HIS FOE AND KILLS HIM, IF NOT, THE BEAR SLOWLY BUT SURELY, CONQUERS THE TIGER AND KILLS IT.

You got any idea from where this source is from?

No sorry, i cant remember. But its based on real scientific data.

Great! That means brown bears are a rare prey item for tigers.

That's right, all you have to do is analyze this predation chart here by The Siberian tiger project, most periods are 0%, the most was  5.4% in the period from 1992-2000, not much for 8 years. But that figure is still not very reliable because its at the bottom part which is "according to tiger's excrement" which means the tiger could have just eat the bear, it does not prove that it killed it. The most reliable is the top part which i highlighted in yellow "according to tiger's prey", and as you can see in brown bears, the most was 1.2% in the period 1992-2013.

All of the sources that I have seen of tigers killing bears are all stating: "very big bear" or "huge bear" but don't show any documents. When the do, the bear looks quite small. Every source says "adult bear" but no "adult male". I have yet to see one that did.
