A vehicle wheel includes a rim, an inflatable tire, a grounding tire, and a safety unit. The rim includes two tire engagement portions spaced from each other in a longitudinal direction. The inflatable tire is mounted around the rim and includes an inner annular bottom wall and two inner annular sidewalls respectively on left and right sides of the inner annular bottom wall. Each inner annular sidewall includes an inner side having a lip pressing against one of the tire engagement portions of the rim. The grounding tire is mounted around the inflatable tire and includes an outer annular bottom wall capable of rolling contact with the ground. The safety unit is sandwiched between the inflatable tire and the grounding tire to couple the inflatable tire and the grounding tire together, permitting synchronously rotation of the inflatable tire and the grounding tire while increasing the anti-slipping effect.
