It's a logo for a tire iron that is depicted by an "X". The "X" is made out of two tire irons that are crossing in the center. Each tire iron are double straight lines with bulbs at the end. Where they cross in the middle is a round circle not one on top of the other.
This is a Tire Iron icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,700 icons, all in the same style and quality.
