Looking for a 1/25 Goodyear tire

I am looking to trade for a particular 1/25 Goodyear tire.  This tire is a "typical" rear drag slick, but this tire comes in (2) half-pieces that the modeler has to glue together to make one complete tire.  The tire half-pieces are made of a slightly-harder plastic than typical kit tires, (but not as hard of plastic as the usual kit styrene).

I think these tires might have come from a 1/25 Johan drag car kit, but I'm not certain of this.  The tire-halves have the following lettering on their sidewalls:

Large: GOODYEAR lettering

Across from the Goodyear lettering, they have small lettering that reads: BLUE STREAK

To the right of the Goodyear lettering, they have small lettering that reads:  8:00/8:20-15

To the left of the Goodyear lettering, they have small lettering that reads:  REAR  FRONT

I'm only looking for one of these tires, (2 half-pieces), as I already have one complete tire as shown in the picture below.
