Answer 1

$str = '175/60 R15';

preg_match('!^([0-9]+)\/([0-9]+)\s(.*?)$!siu', $str,$res);
print_r($res);

$str='5,5 x 15 ET45';

preg_match('!^([0-9,.]+)\sx\s([0-9,.]+)\s(.*?)$!siu', $str,$res);
print_r($res);

Answer 2

preg_match_all('#[0-9,\.]+#i', '5,5 x 15 ET45', $m);
print_r($m);

Answer 3

Not a lot of clumsy way, but still possible:

$str = '175/60 R15';

$str2='5,5 x 15 ET45';


function myfunct($sym = [],$str = ''){


  $editString = str_replace($sym, $sym[0],$str);
  $result = explode($sym[0],$editString);

  return $result;
}

$result2 = myfunct(array("/"," "),$str);
$result3 = myfunct(array("x ", " ET"),$str2);
var_dump($result2);
var_dump($result3);
