What does すねるたちで mean?


i know that たち could be the 2nd stem of たつ or could be the plural indicator,
and i sound a definition of すねる on jisho.org which said

> Ichidan verb, intransitive verb 1. to be peevish; to sulk; to pout​Usually
> written using kana alone

however in the context of the sentence, i can't make sense of it let alone
work out what it means with たち attached.

for context, the sentence is:

> すぐにすねるたちで、すねた横顔はジェームズ・ディーンに似ていた。




The 「たち」（質） is a noun and means "one's nature" "disposition" (≂
[性質]{せいしつ}/[気質]{きしつ}).

「すぐにすねるたちで、～～」 "(He) easily gets peevish/sulky..."

A few examples:

> 父は怒りっぽい **たち** だ。 My father loses his temper easily.  
>  彼女は頼まれると断れない **たち** です。 She (is the type of person who) can't refuse a
> request.
