i dont think i have water in my tires also. i caught a flat on the bike leg during the last mile, so i have a new tire in the front. the rear seems fine too. i have never had water in my tires so i wouldnt know what to look for. i just came from a ride and the tires, chain and sprocket are fine. the GT 85 and chain lube works great. I applied it while rotating the crank backwards. wipped off any outstanding visible dirt. let it sit for wa while. took it for a short test ride aorund the block while shifting thorugh all the gears. after that it seemed fine. today i went out for a 36 mile ride and it was as smooth as can be.
