Regex 查找以下正则表达式模式，我发现这个\w{3,6}\/\w{1,6}[\/\s\-]\w*仍然不起作用

编写一个通用正则表达式，它可以从给定的句子中提取（）中给出的以下模式：

 a) Bridgestone Duravis M700 HD Tire LT265/75R16/10
                 (Extract : LT265/75R16/10)

 b) Michelin Energy MXV4 S8 Tire P215/55R17 93V                        (     
  (Extract : P215/55R17 93V)

 c) Bridgestone BLIZZAK DM-V2 Tire 235/55R18 (100T)                    (Extract : 235/55R18 )

 d) Goodyear Eagle F1 Asymmetric A/S 215/45ZR17/XL Tire 91W            (Extract : 215/45ZR17/XL)

 e) Bridgestone Blizzak DM-V1 Tire 275/60R18 113R BW                     (Extract : 275/60R18 113R BW)

 f) Continental ExtremeWinterContact Tire LT285/70R17/8 118Q BW           (Extract : LT285/70R17/8 118Q BW)

 g) MASTERCRAFT 285/70R17/E COURSER CXT OL TIRE                        (Extract : 285/70R17/E )

 h) Pirelli Night Dragon Motorcycle Front Tire 130/90-16 2211500           (Extract : 130/90-16 )

试试这个：

\w*\d\w*\/\w+(?:[\/-]\w+)?(?:\s(?:\d+[A-Z]\w*|[A-Z]{1,2})\b)*
