BarracudaCast BR32118 - 1/32 BarracudaCast Corsair Hellcat Wheels - Plain Tread 

from the manufacturer:

This set consists of a pair of super detailed resin wheels with 8 slot cast hub and untreaded tires as fitted to some F6Fs and F4Us during WWII. The front hubcap is molded separately to permit the inner hub detail to be properly represented. The rear hub is designed to fit the Tamiya Corsair kit, but inserts are included to allow fitting these to all Corsair and Hellcat kits.
