I battled the tire-shifting valvestem cutting crap for a year. What my problem was that the tires I was using liked to slide in the rim, no matter what psi. After X amount of stoplight takeoffs, the stem would be at a nasty angle, and would eventually get cut. The heavier tube I used, the worse the problem got.
After I switched tire brands, no more problems. I've been using Slime for 20 years and will always use it.
It's gotten me home more times than I know! I've seen it hold air in a tire with cut valve stems 4x in the last year.
Edit: I don't patch tubes, either. 2 reasons: Slime makes it unnecessary, and Slime makes it near impossible.
