This set contains new, more accurate diamond tread tires that directly replace the tires in the Tamiya kit. The problem with the soft vinyl tires in the kit is that the seams are very difficult to remove, and they tend to attract dirt and dust. These seamless resin parts have superb tread detail, and are both sandable and paintable. Four styles are available, and you can even mix and match them, as was common practice on the real aircraft. For modelers building a P-51A,B,C,D or K from Hasegawa, Trumpeter, Dragon, Hobbycraft or Monogram, you will need our resin wheel hubs 32034 as well.
