Multi Parameter search with custom post type category and tag

Ok i manged to create the solution by finding that LIKE condition can be used in meta query. so here is the final code..

$args=array(
  'post_type' => 'tyre',
  'post_status' => 'publish',
  'tax_query' => array(
        array(
            'taxonomy' => 'tyre-category',
            'field' => 'ID', //can be set to ID
            'tag' => 'ID', //can be set to ID
            'terms' => $catid //if field is ID you can reference by cat/term number
        )
        ),
        'meta_query' => array(
        'relation' => 'AND',
        array(
            'key' => 'size',
            'value' => $size,
            'compare' => 'LIKE'
        ),
        array(
            'key' => 'terrain',
            'value' => $terrain,
            'compare' => '='
        )
    )
);

Hope it will be useful for someone 🙂
