This set contains accurate resin mainwheels with staggered block tires, detailed hubs, and fine tire beading. Block tread tires were common among post war Lancasters. They are not appropriate for wartime aircraft, unless you just like the look better. This set also corrects some noticeable errors with the HK models wheels, which are wrong in cross section and the hubs are lacking both depth and detail. An easy and very noticeable upgrade for the 1:32 HK Models kits.
