Another input, I use Dawn, on the inside of my new tires, keeps them from losing air thru the sidewalls, you can test it by using soapy water on them, after airing them up, then ck an untreated one. Glasses fogging, is usually caused by breathing thru your mouth, rather than your nose, you probably don't realize it, but put your helmet on, and try it. The other methods work, but you can't apply it on the track, so learning to breath properly, is a simple fix. Bob!
