WTBVenture TCS Light 650b Gravel Tire(Return to Product Page)

I really like the ride & traction. They are great. However, the sidewalls leak sealant. I've had these mounted for 10 days with OrangeSeal Endurance. The beads are totally sealed, but both tires keep leaking small amounts of sealant through invisible holes in the sidewalls. I wash down my bike and tires after almost every ride, then put it away in my basement. The next day, when I get ready to ride, I notice at least a half dozen pinhead size spots of sealant on the outside of the sidewalls on each tire. Touching them turns my fingertip orange (OrangeSeal). I though the main advantage of the 120tpi & the SG2 concept was to eliminate sidewall leakage??? It apparently doesn't work with OrangeSeal? Before I bought these tires, I ran Panaracer GravelKing SK tires -- they did not leak sealant. I may decide to go back to to the SK.
