Tire - 37 x 18 - #56891

Finally found the exact size 37 x 18 replacement I needed for my Circuit Cubes build — fits perfectly and the rubber has just the right grip for rough terrain.

Wasn't sure a single replacement tire would match the ones already on my build, but the 37 x 18 size and the tread lined up perfectly with the originals. Part #56891 is the exact number I needed, and now the whole thing rolls straight again.

Ordered this 37 x 18 tire to replace one that got lost between builds, and it fit like the original. Nice to finally find the exact part number instead of guessing at sizes. Solid rubber, no wobble on the wheel.
