Tire for preventing irregular tread wear

A tire configured for preventing irregular tread wear, the tire comprising:

• a groove formed on a tread;
• a first sidewall and a second sidewall, both of which forming the groove;
• a reinforcing rib coupled to the first sidewall, and protruding toward the groove from the first sidewall;
• a hidden groove formed in a first portion of the second sidewall which is opposite to the first sidewall;
• and
• a remaining tread part protruding toward the groove from a side surface of the hidden groove, the remaining tread part being a second portion of the second sidewall,
• wherein the hidden groove forms a channel for fluid flow,
• wherein the reinforcing rib has a cross-sectional shape having two parallel straight lines including a first straight line and a second straight line which are directly connected to each other by two opposite curved lines including a first curved line and a second curved line when viewed from an outer peripheral surface of the tire, such that the reinforcing rib has two plan surfaces parallel to each other and two curved surfaces formed on both sides thereof, and
• wherein the first straight line is in contact with the first sidewall and is longer than the second straight line which is parallel to the first sidewall, the first curved line extends directly from a first end of the second straight line to a first end of the first straight line, and the second curved line extends directly from a second end of the second straight line to a second end of the first straight line.
