I took them back to Hobby People to exchange for another 2 sets but they had hairline cracks in those two sets as well. These are not mold lines. The cracks are at different places surrounding the inside hub.

Has anyone else noticed this in their wheels and or had a problem cracking hubs when running? I don't feel like mounting these and wasting a set of brand new tires.
