i want to adjust the wheel angle then move forward depending on angle

// Function to rotate the wheel to the left
static void rotateWheelLeft() {
    if (deg < 45) {
        deg += 2.0f;
    }
}

// Function to rotate the wheel to the right
static void rotateWheelRight() {
    if (deg > -45) {
        deg -= 2.0f;
    }
}

// Function to move the wheel forward based on its rotation angle
static void moveForward() {
    GLfloat radianAngle = deg * 3.14 / 180;
    
    GLfloat forwardX = 0.1f * cos(radianAngle);
    GLfloat forwardZ = 0.1f * sin(radianAngle);

    xWheel -= forwardX;
    zWheel += forwardZ;
}

// Function to draw the bicycle
static void drawBicycle() {
    glPushMatrix();
    glTranslatef(xWheel, yWheel, zWheel);
    glRotatef(deg, 0, 1, 0);
    glTranslatef(-xWheel, -yWheel, -zWheel);

    drawOuterWheel(0.1, wheelColor);
    drawInnerWheel(0.08, wheelColor);

    glPopMatrix();
}

The wheel rotated correctly but when i move forward the wheel moves in a line
