I installed with larger letters to outside on my black walls. I had a bad experience with the tubes that had radial molded on the valve stem. Not the tires fault.
If you don't mind me asking, what was your bad experience with the tubes that had radial molded on the valve stem?
The tubes had rectangular blemishes and leaked from the blemish. I didn’t notice them when I mounted them, but after a short period of time they failed to hold air. Another one of the 5 started to lose air after thousands of miles. When I broke the bead on the tire, the tube was shredded from both sides of the valve stem. Nothing on the rim, tire, that would have caused the failure that I could see. Eventually all tubes have been changed.
