Primo Orion Everyday Wheelchair Tires - Black - 24" x 1-3/8"

Astounding tires.
I usually buy standard Gray everyday tires and they last about 9 months these days.
Within a week the mold seam in the middle is worn away and the tread is beginning to wear.
My new bike came with these Primo Orion Black tires.
THEY DON'T WEAR, or at least not very fast.
I've been running them for over three months and the center mold mark is still present.
The price is only slightly higher and I rate these as a Best Buy in tires.
