* Change 2 Part Black {51011u Tire 17.5mm D. x 6mm with Shallow Staggered Treads (undetermined type) to 42611 Tire 17.5mm D. x 6mm with Shallow Staggered Treads}
Comments from Submitter:
The old catalog entry for this tire combined two distinct versions. The entry has finally been split, and I am updating inventories with the correct versions. There will be counterpart changes in the future after the main parts get sorted out. The changeover occurred around 2010-2011, so all of the early sets must be the old type.
