critical flaw in the construction
- Familiarity: I've used it several times
- Fit: True to size
There is a flaw in the construction of these tires that makes them very difficult to set up tubeless and then unreliable once you get them out on the road. See my photo. For 3 TIRES IN A ROW, a line of bubbly sealant appeared near the bead, around the full circumference of the tire, and on both sides. This happened both at installation time and then later on after just 10 miles of riding. Backcountry was kind enough to replace the first tire that showed this problem. Then it happened with the replacement. Then it happened with the other tire from the original purchase. Forget it, these tires are going back.
Why yes, I have indeed set up many other tubeless tires. Yes, I am aware that even tubeless-ready tires sometimes have imperfections that must be filled with sealant the first time the tire is installed. Yes, I tried shaking the tire and rotating it on its side. Yes, I am aware that more sealant might have helped. In fact it did. Until I rode on it. Or left it overnight in my hot garage.
I don't have time for all that. I have three other brands of tires that were far easier and far more reliable to set up tubeless (Maxxis, Surly, Teravail). And in fact my WTB Horizons also show no such problem. Could you be more patient and make WTB Byways work for you? Maybe. I have better things to do, so I replaced the Byways with the Teravail Washburns, which honestly look to have a better-designed pattern anyway.
