Tangent Scale Models is proud to offer our 33″ “normal tread” CNC-machined brass wheelsets for those who want to replace their current wheels with wheels that roll better and look better than those from other brands. Tangent wheels are leaders in quality in HO scale. We offer them in 100 count bags and 12 count blister packages. Offered in a 1.002″ axle length, our 33″ wheels can be used in trucks from virtually any brand. 33-inch prototype wheels were used on virtually all cars between 40 and 70 tons, making them the most common wheel for steam, transition, and early diesel modeling. Try our wheels to improve the operation of your equipment!
