The NIBT Proving Grounds tested Tiger Ausf.B road wheels on a T-34-85 tank. Trials showed that these wheels are more reliable than those used on the T-34-85 tank.
No defects aside from the loss of the disk attachment cone at 1058 km and four cases of burst welding seams on the rims were observed during 1500 km of travel (of those 567 were on a highway with an average speed of 42.3 kph).
The destruction of rims can be avoided by casting them whole.
Considering the low lifespan of T-34-85 road wheels, I consider it reasonable to produce a batch of road wheels with internal rubber lining like on the Tiger Ausf.B and test them.
Preliminary design for such road wheels was made at factory #183. To finalize the design it is necessary to:
- Make sure that the tightness of the rubber can be adjustable.
- Reduce the weight.
